Peter Harper In Undercurrents No 3, Bjorn Eriksson and I, with a lot o f help from our friends, compiled a 'guide to sources and contacts' in alternative technology. I t served its purpose, but dated quickly, and a new one is long overdue. The trouble is that so much has happened since the paleolithic days o f 1972 that if we tried to cover everything in the same depth as we did then, we'd fill u p a whole issue and more. The only alternative is to break the material up and print it bit by bit-presumably in the usual categories: 'food', 'shelter', and so on.

And that is what we're going to do.

BUT there's one snag: it'll take a long time to get round to some subjects that happen to come low on the list. So this first instalment will be a general selection over the whole field so that people can get started.

Before I start I should say that I don't really 'know' what alternative technology 'is', so my selection is pretty arbitrary. The last list covered what Bjorn and I happened t o be interested in at the time, with odd suggestions from other people wanting a plug for their own favourites. I continue this venerable pattern. Don't think I've read all the books because I haven't.

Neither have I met all the people. I've tried to pick people and publications through which (I estimate) anyone can most quickly get to grips with the 'subject' as 1 see it.

I have taken a fairly 'traditional' approach to the scope o f alternative technology. I don't know whether this is good or bad. Basically it's just me again. There are many things conspicuously absent that might be in there i f I had taken a somewhat different interpretation. To name but n of them: scrap technology (both in heavy industry and among hippy coprophiles), government uublications. extension services. university research (with a few exceptions) DIY facilities and manuals, workshop textbooks, tool suppliers, the Science Museum, community action and people's services, land trusts, moiotov cocktail factories, the commune movement, women's garages, honest farmers, builders, water diviners. technicians of the sacred. . . Maybe

some of these will have their hour in future instalments.

Those who are new to all this might find i t difficult to know where to start.

I've tried to organise the material in each section into a 'basic' part which would probably be best t o start on, and an 'additional' part if you get bored with the first lot. Within each part I've tried to arrange the items In order not necessarily o f quality (a hairy thing to do anyway), but o f accessibility and o f relevance to the centre-of-concern of what I'm calling 'traditional' AT, whatever that may be other than a feeling in the water. For foreign or otherwise difficult-to-get material, I've tried to indicate where it can most easily be obtained, usually by means of Cryptic Letters, to which the key follows: FB = Freak Bookshops: indicates that the item can be found rather generally in movement bookshops, a list of which can be obtained on request from Rising Free.

SB = Straight Bookshops: overground publisher and distributor, so item might be found in WH Smiths etc or sometimes in more trendy or specialised booksellers.

USA legislation. (There is no equivalent UK legislation, and British roads a r e the world's most crowded.)

Stimulated by photochemical smog problems of the west coast cities, the Federal Clean Air Act was amended in 1970 to set in advance increasingly stringent levels for permitted exhaust pollution. Table 2 shows the Californian standards for 1974 and 1975. together with the current best levels of emission for an average V8 engine running on petrol and on propane. and indicates that vropane is far and away the cleanest fuel available.

Even this is not the whole story, for some hydrocarbons a r e more dangerous in the atmosphere than others, although USA legislation lumps them all together.

also present.

What happens when it is burnt?

Because such a large number of differing hydrocarbons occur in i s substantially impossible to in r the right amount of oxygen, and to c the correct combustion conditions, to burn all the compounds comp The emission from a petrol e therefore contains u (HC), carbon monox incomplete oxidation, sulphur oxides (SO) from impurities, nitrogen oxides (NO) resulting from oxidation of atmospheric nitrogen inside the engine, and solid particles. See table l Ăƒ When these substances are in the atmosphere, what happens?

Photochemical smog is formed when hydrocarbons and nitric oxide combine and recombine in a chain of 13 reactions,

There i s considerable doubt that the planet can cope with continued, increasing burning of fossil fuels. An increased level of carbon dioxide in the atmosphere may lead to the build up of a 'greenhouse' effect, whereby radiation i s reflected back to earth instead of escaping to space, the earth heats up and the polar

ice caps begin to melt. (One estimate i s that if all fossil fuels were burnt, then 0 there would be an average 9 C r i s e in world temperature, a 50 feet r i s e in sealevel and a vastly increased carbon dioxide level in the atmosphere).

Only 2% of oil extracted i s currently used a s raw material for the entire chemical, pharmaceutical and plastics manufacturing industries. We h u m 98% of an irreplaceable resource.

Our proposal, that greater use of Liquefied Petroleum Gas should he made, must be seen in this perspective. It too i s produced from oil, and to hurn it rather than use it over great time for the real good of mankind, i s certainly not to b e advocated.

However, if you must power your 20th century personal mobility module with 350 million year old decomposed vegetables, then do it a s cleanly a s you can with paraffin gas. A far better way, though, is to generate and use your own methane - a naturally regenerated resource.

Paraffin gases as an alternative Because the paraffin gases a r e of simple chemical formulae, it i s relatively easy to hurn them completely, a t best producing water vapour and carbon dioxide only. (hi practice, this isn't wholly achievable.)

No additives a r e required.

What a r e the paraffin gases?

The paraffin gases all have the same basic chemical formula CnHn+$.

Because butane and propane a r e relatively easily compressed to liquid to b e transported, they a r e known as Liquefied petroleum Gas. (LPG), since they a r e obtained from oil.

Methane i s not an LPG, because with a boiling point of -159 F (-162 C) it requires refrigeration and pressure storage of considerable sophistication t o b e maintained a s a liquid, though it can be partially compressed for use.

Methane i s sewage gas ....INorth Sea Gas!..

Natural gas. It i s both a fossil fuel and a constantly generated fuel.

Its main drawback i s this: without expensive, energy-consuming refrigeration and compression, and heavyweight storage tanks, it cannot b e easily transported. (However the process i s used, and Algerian methane is imported to UK in refrigerated tankers.) A c a r with an inflatable methane bag at fairly low pressure can c a r r y conveniently only about enough gas for 50 miles. (This may be a criterion for spacing communities in a biotechnic society!)

The immediate effect of requiring an increased output of LPG and l e s s gasoline would be an increased output of diesel oil.

But with changes to refining equipment this does not have to be the case. With sufficient expenditure it i s now possible to'split up the crud^ oil in virtually any desired way.

You can now s e e that there a r e two alternatives for action. The palliative solution, using LPG a s a clean fuel derived from oil that could be put to better uses, i s the one open to you if you a r e city bound.

The Biotechnic solution only works if yon live i n a rural environment with lots of natural waste available, and which will yield gas at a steady rate limited by the size of the input (excrement, mainly) to your degcstors. (Techniques are, however, being developed t o enable even urban dwellers to generate substantial quantities of methane, by feeding digeste r s with special inputs' such a s algae, sugar beet, and other organic material with high photosynthetic conversion efficiency. We'll have more information in up-coming issues of UNDERCURRENTS.) What happens t o the engine running on paraffin gas pollution reduction.

From table 3 it can b e seen that the ideal air/fuel ratio for propane, by weight, i s 15.7:1, For petrol it's 14.8-1.

Therefore, if llb. of the ideal Propane/ air mixture i s burnt. 1280 btu a r e produced. (Propane has 21600 btu/lb.)

And if lib. of the ideal petrol/air

-

Page 28

mixture i s burnt, 1280 btu a r e again produced. (Petrol has 20200 btu/lh.)

The figure for butane i s 1290 btu.

As a consequence of its volatility, methane needs no pre-heating, and can b e efficiently introduced into the engine using the simplest technology. It i s an excellent fuel. having a low flame speed and high octane rating.

Propane and butane, separately and a s various mixtures is available commercially for a wide variety of uses. Oil is currently cracked to yield large amounts of petrol, small amounts of LPG and relatively small amounts of fuels heavier than gasoline. (Such a s diesel oil.)

So from a llb. charge of mixed fuel and air, very much the same amount of power can b e extracted. But of course the LPG/air mix has a smaller mass of fuel. That's good. But it is also l e s s dense, s o there i s some difficulty getting the same weight of charge into the cylinders a s one would using petrol.

Because of this, a power reduction of about 6 4 % is to b e expected. There's nothing to worry about here - y o u ' r e simply using l e s s fuel, and most modern c a r s a r e overpowered anyway.

The inlet valves will run at a slightly higher temperature, but exhause temperatures a r e slightly lower, because the engine i s running with l e s s power. It is said, (particularly by the lead manufaciurers) that lead deposits prevent 'sink' a form of valve wear caused by hard particles of iron oxide embedded on the surface of the valves and seating.

- This

TABLE 3

Pl-hSICAL PR3PERllES

i s dubious, sad valve wear is unlikely to be significantly changed,

The deposition of carbon in the cylinders i s reduced dramatically, and the deposition of lead ceases. Wear to pistons and cylinders is greatly reduced. Oil dilution by combustion products is dramatically lowered. An oil change will last 15000 miles.

In short, if LPG were t o sell at the same price a s petrol, the savings gained through lower maintenance costs and reduction of oil consumption would repay the cost of conversion.

All- LPG containers must have a 'Class I Certificate'. (Home office report on L P containers.) This means they must be fixed in position, b e tested to withstand specified pressure, and have certain fittings and safety devices. It i s not legal to use gas bottles in a vehicle.

The 'Motor Vehicles Construction and Use Act' requires all pipework carrying gas above 15lh/sq. in. pressure to be solid drawn steel, having metal to metal joints. This i s wildly over cautious, an; will be revised soon to allow the use of copper pipe o r bundy tube (brake-line type flexible tube). Since a methane system operates at low pressure, it is outside the scope of the regulations.

But enterprising private motorists woulc b e very hard to trap, and bottled gas is a little cheaper than petrol. And the furore associated with the prosecution 01 a man who refuses to pollute a s he drive would be a delightfully embarassing ever for any selfconscious regime.

Exactly where and how to draw off water-power depends upon ambient conditions and a total energy plan for the area.

The conception of riparian rights (shares in the use of a river) should be extended to include all the communities of the biosphere. Other available sources of renewable energy might appear less tempting in terms of "free" fuel and low labour costs, but in the case of water-power the full cycle of ecological effects is long and full account must be taken even in small-scale projects. An installation which is capable of directly driving several machines simultaneously or alternatively may be more useful than one which crudely converts all of its energy into electricity at high loss.

"Isohyetal" or rainfall contour maps can be used to determine quantities and probabilities of flow. Records of surface water run-off where available are more reliable.

The observed states of water ecology in a stream may also give clues, if we knew just how to read them and could establish a reliable yardstick. (Just such an ecological yardstick has already been developed to give astonishingly accurate information about prevailing wind directions and forces. Five progressive types of deformation of trees are checked by Griggs in Putnam's 'Power from the Wind' 1949). The existence of certain types of planaria, minnow, trout, and roach, etc. together with a knowledge of water purity, temperature and sediment might yield useful information about "stream history" indicating depth and velocity of flow year-round. The roots of trees such as the willow which extend out into the water leave an automatic record of force and depth of flow.

More conventional means of measuring stream flow are given

by Eaniffl. The "bucket method" of measuring flow rate is suitable for y l l streams (<1ft 3/sec.) Medium-sized streams (>1ft /see.) require a "wier" method similar to that described in James Leffel Co. literature and reproduced in UC 2. For larger streams there is an aooroxmate but apparently quite adequatenfloating stick method", as used by Leonardo, whose practice it was to walk along the river bank wheeling an "odometer" and singing musical scales up and down to measure time: The available gross quantity of power depends equally upon flow-rate and head (theoretically P=F x E) but this takes no account of losses in pipework or channel, wheel or turbine, etc. Head is the height of a body of water. An idea of the importance of this factor may be got by puncturing a series of holes up the aide of a can. filling it with water, and observing the behaviour of the jets as it empties. A sophisticated method of measuring on-site head is to sum a succession of measurements made with a surveyor's level and scale, but a carpenter's level or a

Page 31

UNDERCURRENT

Chinese meniscus level and scale would be sufficiently accurate. (The meniscus level ia a bamboo tube floated on the surface of a rice-cup full of water. The tube is used for sighting along). All measurements of flow should of course be made in the season of least flow if a guarantee of "firm" power is desired. Sites on rain-fed streams have an amiual flow pattern phased with seasonal precipitation, but those on glacier-fed streams have maximum flow during melt period. Maximum "finn" power is obtainable from run-of-river type schemes, which rely upon good supplies of running water and eliminate the need for a dam. The least reliable source of water-power is from tidal mills unmodified by pumped storage. In the golden age of tne corn-mill the dependability of water-power was prefered, whenever possible,to the "inconstant" wind. Days of calm or storm could immobilise a windmill, but a well -regulated and well-sited water-mill could depend even in times of drought on a useful head of water. In areas of tne globe such as Europe where mean annual rainfall almost never varies by more than a factor of 1:2, and monthly means are not much more, good sites are not rare, particularly if you are not in competition for the 6 6 or so of remaining unexploited potential at large-scale sites. qchemes are divisible into those without storage and those n t n . There is broad differentiation a m o w t atoram schemes between those using moderate head and large catchment area (e.g. by a wier at the exit to a shallow pond) and those ussng higher head and snaller catchment area (e.g. by temporarily arresting a mountain torrent).

The most successful schemes are modest. If the intake to the headrace represents quite a small proportion of flow borrowed, not only is a "firmw supply better guaranteed, but the stream is less likely to resent your intrusion.

Flood waters overtopping the dam would often be fatal.

Floods must be allowed to flow via a spillway over, under, through or around the dam. A wide spillway crest or vier provides the usual solution. Fast flowing water or water under great pressure is a formidable and destructive

-

adversary. It can disintegrate a dam, push it bodily forwards, tip it over, or gradually undermine it by seepi or erosion at the base.

where there is a naturally high fall of water. The bucket or "float" is designed so ee to retain water until its 'work" is done. Breastshot wheels, like overshot, turn by weight, but in the opposite sense of rotation. The underihot w eel uses heads of la5 loft. and flow rates of 10-100ft./sec. and gives an efficiency between 6675%. The developed undershot or impulse-wheel (a turbine) has an efficiency of 80?&-90^ or more. and is used for high heads and low flow rates. Size and weight per hp is small, Construction of a Nichell (Banki) type turbine is possible with welding equipment and a small machine works such as those used to rçpai farm machinery. With turbines two different principles are involved impulse and reaction.

Impulse turbines use high-pressure jet(a) directed at the buckets. Head of water is converted into kinetic energy.

There is much scope for variation of design and number of jets and buckets to extract maximum efficiency. Reaction turbines uae two sets of curved vanes, one stationary and the other free to rotate. Water leaving the guide vanes supplie~energy to the runner, partly by pressure and part in kinetic form. A totally submerged horizontal wheel would be the logical extension of the principle of the Nichell (Banki) type turbine in which water passes twice through the runner before discharge. A horizontal wheel might work on the principle of the "panemone" ( s e e fig.

5 in John Wood's article in UC 5 ) , and would presumably be relatively large, and rotate slowly but with high torque and be suitable for use in rather sluggish streams.

Pile-driven planks are used to prevent seepage. A timber d m is capable of forming its own spillway over the crest.

Concrete and masonry dams must be built down to a solid footing to prevent leakage and shifting. Spillways present few problems. Tensioned tarpaulins have been used recently in Russia to provide cheap and easily re-locatable water-power from small-scale sources. Adequate

This power is most useful for slow-speed applications, though DC generation is possible. Gearing and belting (with inherent friction loss) is required to run most machinery. Suitable applications include flour-mills, agricultural machinery, pumping for drainage or water-supply, forge-hammer, blast-furnace bellows, fulling of cloth, sawing timber, domestic equipment, and processes mch &B paper making and manufacture of explosives.

Constant speed-regulation is barely practical, so water-wheels are used primarily to drive machinery which can take larffe fluctautions in rotational speed. A water -wheel, became of its rugged design requires much less attention than a turbine. It is self-cleansing. andunlike a turbine does not need to be protected from debris.

The horizontal wheel of the Norae-inill is capable of a rather inefficient 0.5hp sufficient however to replace a moody donkey with a "tireless" machine. Vertical wheels are of three main types overshot, breast and undershot.

The terms refer to the point at which water flow actuates the wheel. The first two use weight of water falling into buckets, while the third is driven by the force of the current, as is a turbine. The overs ot wheel uses heads of 10-50ft. and flow rates of 1-50ft /sec. and gives an

Gearing with wood engaging in iron reduces wear on slowspeed machinery. The two different materials "marry" better together, quieter and smoother running being also obtained. In the traditional European water-mill the primary gear-wheel was of water-resistent oak, and the other gears would be of hardwoods such as apple, hornbeam, beech or oak. Paired gears were not placed in exact ratio t.3 one another but differed by + one wandering tooth. This wae another trick for reducing wear. Wooden cogs or teeth were either dowel sections with rounded ends engaging in a "lantern" wheel, or beveled chips of wood wedged in place between a pair of iron hoops. Gears would be engaged or disengaged to drive machinew according tc the flow of water and the demand for power.

E-LEC-T-RIC-ITY

! ,

An electric water-power installation can produce either DC or AC current. DC current is just as @ad as AC for producing electric light, running a radio, etc, but for most existing household and agricultural machinery which was built for the national grid an expensive replacement of all motors is necessary, DC current does not require regulation of the turbine or wheel, but banks of storag* batteries will be necessary. In producing AC the flow of water must be constantly controlled by some kind of cybernetic device, which is characteristically expensive.

Flow regulation requires governors and complex valve shut-off devices ocsting more than turbine and generator combined.

assumption, of peop c linkerin& vk I n tcchnuloeici.il ,itcrndl,&esthere d r ~two ' main blocs -those that think the system is bound for physical collapse; -those that think the system i s evil.

Of course there's noreason why you can't think both, and that bias on my part will be evident throughout. But basically, there are those who worry about environment and resources, and those who worry about alienation and exploitation.

For convenience, let me create two Procrustean categories to reflect these emphases: Ecological Alternative Technology (EAT) and Radical Alternative Technology (RAT). I'm going to argue that both approaches have failed in theory and practice because they have neglected a large part of our lives and our technology, namely, basic production, which requires not so much alternative technology as alternative organisation, therefore alternative economics, therefore alternative social expectations and institutions, therefore alternative politics, hearts, minds and eventually back round to wherever we started (to be sung to the tune o f 'Dialectics Blues').

Let me go into this a bit more. Our technology can be divided into two parts. To oversimplify, there is the domestic technology of the things we consume directly: fires and boilers for heating, lamps for lighting, stoves for cooking, cars for travelling, televisions for watching Monty Python, and so on; and there is the technology of the means needed to produce all these: steel mills, mines, assembly plants, research laboratories, transmitters and so on.

There i s a continuous range of things in between, of course, but crudely speaking, there's the technoloyy.ofconsumption (TC) and the technologyof-production (TP). ' A T ' o f all kinds has focussed very heavily on the former, although we spend at least half our waking lives on the latter.

The reasons ton this imbalance are interesting. An obvious one is that part of the purpose o f small-scale self-reliant technology in both EAT and RAT camps has been twcut out the TP as a separate category and blend i t with TC. Another reason is that small-scale types of A 1 do not lend themselves to a separate TP as i t has developed: the very reason for taking TP out of the home and into the factory was to achieve economies of scale by concentrating into big units; Related to this is that modern TP is very complex indeed and most AT freaks wouldn't know how to even begin creating technical alternatives, apart from closing the whole lot down. And another reason is that most AT folk are middle class, a large proportion of them superannuated students (and I speak as one myself) whose only experience is TC as far as they are concerned that i s what lechnology is: they've never experienced the inside o f d factory. Over and over again, Page 36

(Check this out: make

case) but unless complete self-suf is achieved. the ouestion o f oroducti i s one which must be answered unless you think there's nothing wrong with the 'Adrian' syndrome).

All this is certainly true among the eco-freaks, but paradoxically often true also o f the radicals. In Stefan Szczelkun's latest (and mind-blowing) Survival Scrapbook on energy it says: 'Criteria for selecting information: "1 That it should be able to be used and controlled, on all levels, by individuals and small communities.

Small scale. Decentralised.

2. Able to be used maintained and constructed by amateurs. Specialist knowhow demystified.

3. Makes use of local or commonly available resources whenever possible.

4. Poetic rather than banally convenient.

5. O f use to those who actively confront the inadequacy o f our present state'.

Actually, that's the finest RAT list I've ever seen. Notice there's not a word about ecology. But, except for a hint in No 5, neither is there a word about the reorganisation of production of insulation materials, thermoelectric Jevices, solar fridges, generators, water pipes, gas heaters, air drills, heat pumps, steam engines, all o f which are found in the pages o f the book.

Now comes a rather nasty difficulty. it's relatively easy to create consumption-alternatives because we have fairly direct control over the technology o f consumption (although few o f us may exercise it). Creating alternatives in the sphere of production i s not so easy because it's such asocial thing, far beyond the control of most individuals (which is largely what's wrong with i t anyway) and it therefore requires massscale political action to change. Must we then wait till After the Revoluti That is indeed a possible strat and frequently hawked in the Street on Saturday afternoons, personally 1 think it's like waiti Godot, or the apocalypse, or th issue of Undercurrents. (You're ir again!-Ed).

problem is, how to get our fingers i n th crack. My thesis which I shall expand ir the next article (this is getting ridiculoi is that 'premature' attempts to create alternative social, economic and technii organisation for production can contribute in a significant way t o the achievement o f political conditions tha will finally allow them to be fully implemented. This is by no means the only part of the strategy, but I think i t s a vital one.

Next problem. What kind o f alterna live society/economy/technology do we want? I've already argued that at least in the sphere o f technology the 1c of agreement on what we want i s rathe poor, and that we will have to sort ou. least roughly where we're going. And of course the same i s true of economy and society, for much the same reason' I find it helpful to divide the problem up into a theoretical bit (what do we ideally want?) and a practical bit (whx do we do now). This article mainly concentrates on the theoretical stuff because I think it clears the head (well sometimes). Once again for space reasons I defer the living .,trategy to the nexi: issue.

To illustrate some of the possibiliti, I shall use the three paradigm societies imagined by the Goodmans in their celebrated Communitas, written in 1947. Each of the three different type is perfectly rational and just. They could be socialist societies in which arbitrary privilege and ccor.umic competition had disappeared

NDERCURRENTSI6

I have corrupted the Goodmans' ree types by casting them in the form o f some diagrams of my own. They ce the whole issue to three quesh o w long do y o u work? how able is work? And how enjoyable -working? I assume that each is equally rational, that is, the o a enjoyment is the same for each.

Type I putsa high value on consumption. The 16 hour waking day is divided

in half: 8 hours work, 8 hours

At least this much can be said for type 111: a quarter of your time, however distributed over your day, week, year, life, would be enough to keep You alive. The rest o f the time you would be free to do type I1 work or even type I work, as long as you didn't annoy every one with your noxious emissions or whatever.

This seems t o be an attractive scheme. Question is, what are necessities? How much time should be spent in providing them? How much can be managed locally, region ally, nationally? To illustrate some o f the alternatives, we need to compare some possible 'AT* societies at different scales. Obviously there is going to be a profound difference between neoprimitive alternative technology societies which take all the slogans about self-sulficicncy literally, and more sophisticdted ones that mdy have the same slogans but don't really mean it. *

output would still be very low: not many goodies. I n fact work is justa as enjoyable as leisure, as i f you we doing a hobby all the time, and the distinction i s virtually 10s

The trouble about type II i s that not every body fancies it, to say the least, and a single system o f that type wouldn't allow people much choice.

as near as anyone: 'Soft technology is by no means novel; man has used it for thousands of years without realising it, without defining it, because that is all he knew.

What has made soft technology significant is the 'hard' technology weighing us down and drowning us in the industrial society'. . . .we should make a distinction between: soft technology used by the 'fringe types', technology which i s not very original technically speaking, but which is 'soft' because o f the way they u w it; and t0f1 technology with in the esldblithed culture wh1i.h !\ill become (technically) very sophisticated but not at all 'soft' because it is meant only to extend current technology'.

It i s certainly true that soft technology means giving up some facilities, even comfort to a certain extent'.

This is essentially anon-industrial technology. I n his view, any technical alternatives which do exploit recent advances risk 'falling into the trap o f perfectionism, and reinventing (without realising it) the very universe we wish to flee'.

I call thisvariety of ATsimple AT (SAT). Ivan Illich's writings often seem to point in this direction although they don't go quite so far. Illich seems to share with Arreteau a sense o f the aesthetic or spiritual advantages o f the simple life-his phrase i s 'a conscious politics of austerityp-an idea with some very beautiful precedents:

People would be essentially free ganise their own economic life patterns, individually or i n groups. J o b rotation (mental-manual, industrialagricultural, urban-rural) would probably be more feasible in case B. Whatever the balance of 'centralised' industrial production to local production (1 0:90, 5 0 3 0 or whatever) i t is important to consider what should be produced and how. Currently nearly everything is made 'centrally' and distributed nationally.

All kids would play with as they grow up, and they would the mechanical basis of the local munity's technology.

Where have we got to? I've tried to show that 'AT' is :concept without a clear meaning: There are lots of people going in different directions but thinking they're marching shoulder to shoulder.

The technical realisation of the typical AT' ideals is problematic even in their n terms. And in terms of wider radical als, typical 'AT' activity does not p the struggle for a more humane and Ifilling society. I would like to see the mphasis shifted or at least the centre of ravity, from technique (gadgets) t o rganisation; from ecological considerans t o social(ist) ones; from consumption t o production. I've even thought - of aslogan: FROM THE TECHNOLOGY OF CONSUMPTION TOTHE ORGANISATION OF PRODUCTION I don't want to imply that there's no technical work to be done. There's plenty, and what we've done is not wasted. But it must be integrated into the rest o f the (?) strategy-politics, economics, social organisation, life, love, poetry ., Somebody wrote to me after the last article 'it's not necessary to talk about t it will be like: (it won't be anyway)' mpathise, but I think ranging shots useful i f only as a first check that here we're going is really worth it, and to rouse the juices of the imagination.

But o f course all that Utopian theoretical bullshit has used up the space again and I haven't got round t o what I was really supposed to talk about: Utopianism as a dialectic-smashing strategy-the art of behaving as if the revolution has already happened, and getting away with it.

Geoff Watts looks at tumours and human ecology ALTERNATIVE CANCER RESEARCH nothing to do with wind pumps, water power, solar energy or recycling technology You can't do i t in your kitchen-let alone the back garden-and most o f the people working on it would probably refute the term 'alternative'.

They would see it as nothing more than a logical step forward And so it is-hut an especially important one.

The poor results o f most early attempts to hack tumours out with the scalpel, or batter them into submission with X-rays, forced clinicians and bioiogists to face up to their total ignorance of cancer. They began to wonder how the process started, and what i f anything cause'd i t As more bits and pieces o f information emerged, interest and enthusiasm grew. The cancer research epic was launched Efforts have been fruitful (superficially, at least) and the l i s t of known carcinogens continues t o grow This list, however, has been viewed largely as a register o f 'things'. things which cause cancer. Now a whole new stream o f thought i s beginning for the first time to be taken seriously. the notion that at least some be influenced by the suf mind, might perhaps even be a direct result of it In other words, cancer as a reflection o f the way we live.

There'-, nothing new about the notion of psychosomatic illness. we've been connecting stress and ulcersfor years But such ideas have never been popular with the cancer researchers.

Indeed, they're hardly widespread nowbut they are beginning to become respectable.

The Faith Courtauld Research Unit at King's College Hospital Medical School i s a case in point The unit i s now in its third year of a study aimed at unravelling the psychobiology o f breast cancer. The staff are trying to construct a complete picture of a series o f women suffering from the disease. not just their physical, but their mental condition as well. In the words of one of the group, 'We want to find out exactly how the patient's biology, especially her hormones and immune responses, interact with psychology i n the origin and development u f her illness. kor example, could stress be playing a part in its origin' is

T h e division between mind and body must be broken', the group iii5ist. '11'5 quite possible that psychosocia! factors contribute to cancer, but up till now Ihdt possibility has been largely ignored'.

The various enthusiasts for research in this field have even come together in an organisationwith the rather mouthy name of the European Working Group for Psychsomatic Cancer Research. EUPSYCA for short. This worthy body held i t s second seminar last October (on 'psychobiologic, psychosomatic and sociosomatic aspects of neoplastic disease') in an appropriately obscure region of Slovenia.

meteorological stresses on cancer', 'Schizophrenia and malignancy' or 'Rorschach (ink blot test) investigaiions in ovarian and cervix cancer patients'.

Then again there was 'Sponr~neous paintings as an expression of the total personality with specific reference to malignant tumours'and 'The role o f aggression i n neoplastic disease'. You see, it all plays a part-from art to the stale of the weather.

The psychobiologists obviousiy appreciate that they may yet be in for a rough ride at the hands of their lcbs open-minded colleagues: witness one 01 the conference sessions pompously ! $ 8 : accurately-entitled 'Profes'Ă&#x201A;ÂĽ.ion.~ and popular resistance againsi the p-A-J.,:! matic cancer concept'.

the Art

It i s in the nature of sf that i t comnents either overtly or by implication on our present world, and the course that it may take i n the future. I feel s f is not concern ed mainly with science, i t i s concerned with entertainment, social comment and people. Even the classic 'hard' sf o f writers such as Asimov is not read f i t s scientific content, but for othe reasons: Asimov's famous Founda trilogy i s a rewrite of Spengler on galactic scale. His other books are cellent detective stoires, put togeth with science that is inconsistent an as gadgetry for the characters to exploit.

Leaving aside a lot o f sf-far futures, 'space opera' and so on-I want to con sider mainly the near future' how dc authors see the patterns of society altciing m the next few hundred years? What resolutions o f the problems that face us today are envisaged? Population, pollution, resource use, atomic warfare, violence and many other themes are reflected, changed, and distorted in the mirrors of sf, the mirrors of the possible futures. And what role does science play i n all this? To many writers, science i s a tool to allow their characters room to act i n new situations, to extrapolate human behaviour in imagined futures Take Bug jack Barron by Norman Spinrad. Here i s a novel where the protagonist i s made immortal by a process whose nature he does not know, but which is under control of a megalomaniac millionaire. As the nature of the process unfolds and he finds out how he was made immortal (a nasty operation involving lingering death for a child) so the moral conflict becomes apparent, and the new choices and situations available throw the relationship between the characters into high relief.

However, this calculated use of small amounts of scientific extrapolation to create a new and valid situation is not the only way science i s used in sf At another extreme o f sf (and there are seveiitl) lies the use of science as a gadget-provider in games of interstellar cops and robbers, or more often, as with Poul Anderson's last few novels, interstellar capitalism and colonialisin with the 'good' guys trading with and ripping off everyone they meet.

Usually in this type of book it is only the supposed benefits o f capitalism that are allowed to appear.

Which brings me to another point. who do sf authors portray in their work?

The two extremes are 1 ) a small group of people. in powerful positions, in their world, having adventures unrelated to the rest of the world; and 2) people related to, and put in the perspective of. the total society portrayed. The important question is whether or not the author's creation is self-consistent In the socially unrelated category I put much of Hemlein, Anderson and Frank Herbert (eg Dune) and most space-opera man-saves-the-universe stories In the second group are those which do present a total view o f the author's world, where the characters can be seen i n relation to society, rather than in chauvinistic isolation. This is not to say that valid and telling s f cannot be written without relation to the whole of the human society at that time, but that many authors deliberately ignore issues that are central to the working o f the vision they are trying to capture.

Many short stories, eg The Cold Equations

by Tom Godwin, deal with a type o f situation that could arise anytime, and bring out the human reactions to the situation; other stories and novels such as Robert Heinlein's Starship Troopers present the reader with characters whose world is a fait accompli, and consider the adventures of one group from one class without relating this to the rest of the society portrayed It i s worth discussing Heinlein for a while, as he i s one of the most influential of the old guard o f sf writers, has written a book, Stranger in a Strange Land, that has >old more copies than any other sf novel, and writes from a right-wing if not fascist viewpoint. 'Starship Troopers' won a Hugo award as the best sf novel of 1959 It portrays an earth fighting against an external enemy 'the Bugs' who cannot be communicated with. The worlds under earth's influence, where not under a benevolent martial law, are run on a democratic capitalist system, with voting limited to those who have served in the armed forces for two years. Flogging and hanging are civil punishments and glorious death is rife in the army. This fascist set up i s justified, in the words of

the hero's tutor in Moral Philosophy ' . . because it works'. Now the hero is an upper middle class lad (house, swimming pool, father's firm, shares etc) who joins the army and likes it. He trains, fights, talks, and gives his view o f militarism as not onlv a necessary, . . but also a desirable way o f life. Militarism is justified also by 'the Bugs'-the main reason for there being a huge army. A friend o f mine on readine this book said he could now see what attracted people to fascism.

To return to the original point: at no time in this book doesHeinleinrelate to the whole o f society-action revolves around the army, the training camp, and an upper-middle class household and friends. To me this i s a distortion of his possible future. Having set up the situation he loads his characters to give a picture in which the values o f fascism seem natural: no space i s given to any who might have disagreed with the system, the social implications o f capitalism are ignored, and the highest aim of science is given as provision o f better weapons.

From the distortions o f Heinlein let me turn to those who have at least attempted to present a total picture of a future society and relate their characters to it.

Much of the best in sf results from the author's skill in setting up a possible future world and following its rules to produce relevant human situations, rather than the gadget surprise-ending story. That is, the restrictions of the future society are seen to be operating on the characters.

One set of near-future novels are the post-atomic war stories. Here a change so dramatic has happened that the resulting situations have varied enormously.

Classics include The Chrysalids by John Wyndham, the film Dr Strangelove and A Canticle for Leibowlz by Walter Miller.

This last i s particularly interesting. After the war most knowledge has been lost. science is in disrepute, and a few monks carry on the traditions of knowledge against the general trend; eventually science is brought back into use. This book considers in detail many of the moral issues resulting from the use of scienceand the mystifications surrounding it. , More interesting still are works considering the near future where there has been no cataclysmic disaster. These deserve a fuller discussion, but to mention some briefly: Make Room! Make Room! by Harry Harrison. Here science i s seen as impotent against the massive rise in population; all life has become narrow, enclosed and basic. Now filmed as Soylent Green.

UNDERCURRENT! Stand on Zanzibar by John Brunner.

The title comes from the estimate that in the year 201 0, to give each person in the world 1 sq ft of space, an area the size o f the island of Zanzibar would be needed. The book features the computer Shalmaneser, the nearest man has got to artificial consciousness, and gives a horrifying view o f a future military brainwashing technique used to make a man an efficient killer. The treatment of these and other themes in this very long book (% million words) brings out perhaps the most total picture yet attempted o f a near future: the effects of pollution, mystification o f science, specialisation, military abuse of science, capitalism, and especially overpopulation are related to characters at many levels of this vision of 40 years ahead.

Camp Concentration by Tom Disch.

A variant of syphilis is discovered which increases human intelligence at an increasing rate after infection, but causes gradual breakdown and death of the very intelligent subject after some nine months. I n a military confrontation situation the army trol and infects some conscien objectors and military criminals. debates on the nature o f science and the way science drastically affects this future society make the book well worth reading.

I n short, some of the best science fiction not only considers in a tangential but radical way^the moral issues raised by science inour present society, but also by extrapolation probes many situations that have not yet occurred but which do have some bearing on the way we think of science.

WINDMILLS -continued from page 22 To make things easier, cut out a template from strong cardboard That way you are more likely to obtain 3 very similar blades. (the best tool to use for carving the blades i s a spoke shave I t should only take you a couple of days to come up with a fine set of blades).

For the haft piece, the ends of the boards will be doubled on either side by glueing on a layer o f wood, and then carving and filing, and smoothing down to get a dia o f 54 to 60mm according to the dia of the blade support tubes M, brazed onto the cylinder of the wheel hub as mentioned previously (see fig 5).

With the three blades now well smoothed and even, you must now give

boiling water, removing and tightening the blade in avice, then making a small press with two slats or brackets, upon which i s placed sufficient weight for the warping to be measured with a protractor Adlust the position o f the wood so as to not make a larger angle, and let the bldde dry in this position (see fig 5).

Next release the blade carefully, and aoolv 3 coats of cellulose or oil based varnish.

The cylindrically shaped base o f each blade is then set and tightened into the tubes M with small bolls, i t nlav also be advisable to make a few holes for screw fixing to prevent the blades from slipping.

The blades arc wedged at an angle of 220 with the flat surface of the cylinder as in fig 4. This angle can be altered; the smaller it is the faster the propellor rotation speed but i t is also more difficult for i t to turn. A larger angle gives the opposite results. But 22O is a good average.

The dvnamo to be used is a 6 or 12 volt car dynamo (can you still get 6v dynamos? I t may be necessary ro rewind the dynamo to reduce rotational resist~

ance and also to provide 6 volts necessary; a modern car alternator ate successfully in this set up, you cot also try running an electric motor in reverse) with circuit breaker, but chec that they are in working order.

I t will be turned by a friction rolle (fig 1 & 4) fitted to its axle and supp* i d by the interior of the brake cylind of the wheel hub. The friction roller i made o f a series o f leather discs, tiqhl ed by bolts that span the length of th roller, between two steel washers.

The dynamo is fixed by a flat iron tightening ring S (see fig 4) on a nut. i lock nut, on the end of t h ~ bolt and . tube P designed for this (fig 1 ).

The ring S is placed i n such a way that the friction roller constantly anc tightly presses against the brake cylir keeping the dynamo activated by the rotation o f the propeller.

To maintain permanent sup o f power, a storage battery and con panel are used. This consists of a 6 c volt battery o f high capacity (100-1 amplh), or a bank of several batten in parallel, and placed in the house workshop to be supplied.

TOWARDS THE END of his immense book Total Man (Allen Lane), St Gooch has an interesting confess throws new light on the whole thin 'When Imyself experienced the mediumistic trance for the first time subjective concomitants were, in this order, a wind rushing through the he0 a sense of being engulfed by somethin with awareness dwindling rapidly to a pinpoint, followed by unconsciousness.

The onset of the condition was very sudden, giving the impression ofsome (damming) barrier having been broken through '.

Apart from this tantalising fragment, / e learn nothing more of Stan Gooch's ni'r'innal exnerience of 'tne dark side of r..-...-...7~~the mind'. But it it enough to account for his obsessional interest in the subconscious. I t must be a weird experience to have yourself 'taken over' by something alien.

to have yourself 'taken over' by something alien the new are significant. The new brain is abqve, and this is why we speak of 'higher things', o f gods dwelling in heaven or Olympus; the old brain is below, hence devils i n hell (the underworld), dwarfs who live in underground caves, and so on. In what he admits to be a wild piece of speculation, he even suggests that the old brain may have been able to somehow see the new brain stretched out above it, and so derived the idea of heaven as a starry firmament.

A very large part of the book-about 90%-is given to setting out the different realms of the old brain and the new, and assigning all kinds o f phenomena to one realm or the other. For example, he sees communism as essentially a product of the cerebellum (old brain), with i t s emphasis on human sympathy, on forces from 'below', while fascism

I actually read through most of Stan Gooch's book in a single day, continua ly amazed and delighted by his skill i n the handling of ideas. He brings in so many weird and unexpected illustrations that you can almost enjoy it purely as imaginative literature. Just as a piece o f intellectual trapeze-work, i t is quite stunning.

But how far does it hold water7 I have now read it twice (I reviewed it for another magazine when it first came out), and I'm s t i l l by no means sure.

I'd better disclose personal bias here.

I am also inclined to divide man into two parts; but not the 'Self and 'Ego'.

I'd suggest that the main problem of most living creatures-especially manis that they are too 'automated'. I am able to type this review without even thinking about my fingers because the typing is done by a kind of robot inside me. T, the active, willing 'me', has only to worry about Stan Gooch'b book, and how to outline i t s arguments to my readers; my robot does the typingfor me. The trouble is that this robot takes over many of the things I don't want him to do for me. I can eat, drink, take exercise, even make love, 'automatically', but I don't get as much fun out o f these functions as I do when 'the real me' performs them. But whether I like i t o r not, the robot does a great deal o f my living for me. I am inclined to see the basic psychological

based on myth and symbol, and on powers of the mind that are unrecognise by ordinary consciousness. 1 accepte Graves' view and developed i t at so length in a book called The Occult.

Gooch's book is also based on this I although he speaks o f 'Knowledge I a 'Knowledge II' instead of solar and lunar knowledge. The antinomy is erected into a vast theoretical structure that is full o f originality, and the fact that Stan Gooch argues from psychology and biology as much as from mythology and poetry gives his book a scientific dimension that Graves lacks. Like Graves-and Jung-he suggests that the I Ching i s a good example of a lunar knowledge system. And at this point, the reader waits for the argument to take o f f into realms o f parapsychology and occultism -where it is obviously headed sooner or later (perhaps in volume two). But it changes its mind and turns back, just at the point where you feel the revelations are about to occur. There's a feeling of

an interrupted orgasm.

Still, apart from that, it's a remar achievement, probably the most interes ing work of non-fiction published in 19' I was naturally curious about its author; so when I was asked to writ about the book, I was glad to take opportunity to meet Stan Gooch. I quite sure what to expect. The nam conjures up a large, clumsy individu with horn-rimmed glasses, a Yorksh accent and gaps between his teeth. T reality was less jarring, i f less unusual; a smallish man with a dark beard, dress in casual jeans and sweater, with a with drawn manner. The accent was Londor insofar as i t was anything-he was b in Bermondsey, which also produce Tommy Steele, Henry Cooper, M Bygraves and Michael Caine; like t Stan Gooch is working class. He told his childhood had been shy and 'extrer ly neurotic'; he read obsessively-'I'd read every book in the local library by the age of 11 '-and later developed a duodenal ulcer and migraine. He endec school with a surge of brfUiance, collec ing just about every prize, then spent several years drifting from job t o jobincluding schoolteaching in Birminghai and a year as a scrap iron merchant.

Something was trying to get out, but h wasn't sure what. Not surprisingly, he had a nervous breakdown, and, at anol point, became a spiritualist medium, 11 was while he was reading for a teachin diploma that he came across the work of Karen Horney, and suddenly made the dizzying discovery of depth psychogy. He became a senior research psychologist, explored half a dozen more dead-ends-including an unsucce ful marriage-and finally started to write novels and poetry.

the neuro-physiological approach gives it a down-to-earth feeling which I find lacking i n lung. The dozens o f references to animal behaviour relate it to the work o f Lorenz, Desmond Morris and Robert Ardrey. Germaine Greer, Shulamith Firestone and co should be delighted with all he has to say about woman: that she is basically a different kind o f creature from man-almost a different species-and ought to firmly reject the temptation to imitate man in his own fields. The political implications should please the left wing which, like Woman, has i t s roots in the 'old brain' and the old knowledge. At the same time, Mr Gooch is far too much the outsider to be bound by any ideological loyalties.

I n the final chapter, he makes it clear that he i s not interested in the conflict o f old brain versus new brain, Knowledge I versus Knowledge I, but in transcending both of them. His basic argument is that if man can take the Self fully into partnership, most of his present binds and blockages will disappear-along with the psychotic civilisation-and h will develop a range of powers beyon anything he can at present imagine. I is this evolutionary flavour that give book i t s urgency, so that even wh the argument seems weakest, ther still an underlying sense of overal vision. If Stan Gooch is right, the book is very important indeed; an even if he is half-wrong, he is still of the most exciting and original thinkers to appear in many years.

Total Man by Stan Gooch, Allen Lane, London (1 972) £4.50 The British paperback o f Total Man probably won't appear until the end o f this year. £ 50 i s rather out o f the reach of Undercurrents readers, but the American paperback version can be obtained from Compendium Books, 240 Camden Hieh . Street. London W1 8 0 s .

Stan Gooch's second book Personality and Evolution (Wildwood House) has now appeared. Within a few weeks of publication it was chosen as one of the Sunday Times books of the year by Jacquetta Hawkes Although savagely attacked by the psychology Estabhshment, the book has generated enough interest to merit a full-length interview from the magazine WorldMedicine and an invitation to the author TO speak at the world conference o f the Health For The New Age Trust (see p8 this issue).

Can plants read thoughts? Can they transmute the elements? A book published i n the USA late in 1973, The Secret Life ofpiants, claims they can. Jamie McCullough is himself engaged i n research on the stranger capabilities o f plants, and he talked about the book to Tony Durham.

They 're not scientists?

Absolutely not. There's no sort o f critical faculty at all I mean the thing's full o f illustrations. They could afford to illustrate it But there's not one drawing o f one plant.

What are these illustrations?

They're just, you know, a sort o f art nouveau chapter headings.

It's quite a beautifully produced book really.

It is, yeah. It's nice art nouveau, sort o f dreamy illustrations, to go with the chapter headings. They could afford to illustrate it, they obviously didn't have any problem about that, but there's m e THC

The whole thing goes on about/plants can do such-and-such' but there's probably only about ten different plants mentioned by name in the entire book.

Isn't there an audience which would actually like a book like that and would hate the scientific details?

I think it's h i t the best-seller lists in the States, so obviously there is. It's your Life magazine, do-you-believe it-ordon't-you sort o f Reader's Digest how-1found-God-through-the-plants sort of thing.

What strikes me Is that books of this kind-I felt rather the same about 'Psychic Research behind the iron Curtain3-i felt that it's a b i t like a tit magazine, inasmuch as it indicates without revealing.

Exactly the same psychology, right.

And 1 suppose in that way it's splendid.. more t i t s per square yard than . , you know! Club International o f the psychic world..

But what about the serious audience?

The audience who would love the scicntific details reads the technical journals, and this wouldn't be allowed to come out there. It's one o f the heresies. So the only way thiscan get around i s in this rather garbled way. The fact that they've put it out will bring it to maybe 50 people who'll start experimenting. It's definite plus and it's good that they , -ate it at all.

Is that a bibliography at the end there?

It could be the most useful thing in the book.

SURVIVAL SCRAPBOOK 5 sets out to centralised and non-destructive generation and uses o f Energy.

It's very pleasing to see all or most of the threads of Alternative Energy Technology drawn together in a single work, and the book i s an effort of considerable merit and scope. But it is marred by two faults: poorexploitution of the format, and frequent superficiality.

To deal with the less serious fault first; the book's format seems to have emerged from very confused thinking. Enormous amounts o f paper, perhaps half the volume's total, are simply wasted not, for instance, accept any plea 'poetic' justification for the inclusion of a small picture of a man standing on what looks like an oval carpet in the middle of a blank page, followed by two more pages completely blank. In all, ten of the book's 126 A4 size pages are completely blank. The rationale for this is that the space can be used for 'quick additions' (notes) by the reader, an idea which is largely rendered redundant by the fact that the whole volume is also punched for filing in a ring-binder, with a non-numerical indexing system to facilitate additions and extensions.

Throughout the book, the actual information density i s strikingly low.

Most of the text is hand-lettered, though several different typewriter faces are also used occasionally and there are Page 48

from Raoul Vaneigen I like a great deal, but I question the need to set them out on their own on two A4 pages with about 200 words on each.

All these idiosyncracies for me add up to a major access problem-a subtle alienating effect which encourages skimming from one pretty picture to the next.

Neither i s it exclusively format shortcomings which evoke this response. One of the criteria for the selection o f information, stated on the opening page, i s that i t should be 'poetic rather than banally convenient'. This unfortunate phrase provides considerable insight into the philosophy of the book. Most, though not all, sections lack the depth and precision that technical readers tend to expect. Of course this can be countered by saying that the 'Survival' series is not intended for technical readers, but i t is surely intended forpractical readers, and few of the articles contain enough 'meat' to get a project o f f the ground without iirther reading. Those who are content merely to daydream about AT may find a great deal in the 'Scrapbook' to whet their appetites, but i n most cases practica1 action would require recourse to some o f the books listed in the excellent bibliography. Ă&#x201A;ÂŁ1.5 however seems a high price to pay even for a first-rate book list. I f this criticism seems harsh,

consider the ins parabolic sunlight-reflector below: 'Plywood knife edges of parabolic curvature are use (sic) to shape wet sand in a box by rotating them aboui a central pivot. Wet plaster is then carefully poured into the sand moulc A hollow plaster mould is made In this way. Removed from the sand i t smoothed until perfect. This mould is then used to make a glassfibre (grp dish into which may be stuck small mirrors or 'orange peel sections o f metalised plastic '.

This i s accompanied by a diagram w h i d (at least to me) i s totally baffling. However the prize for obscurity must go to a single rhetorical (?) question accompa ing a picture o f a working elephant in the 'Animal Power' section: 'Cruelty a critical conceptual confusi In short, the 'Energy' scrapbook trie! to cover too much territory in too few words and the author underestimates th sheer difficulty of writing a clear exposition that anyone can understand.

Balanced against this, of course, is the terrific range o f topics that are touched on and the size o f the mass audience thr it is going to reach. The annoying thing is that with so much space available many of the worst difficulties could ha^ been overcome and we might have had a standard 'soft energy' textbook of lasting value and importance.

Abacus, A-bomb...

Part-works have, in the last ten years, become very much part of British blishing, and Marshall Cavendish i s e o t their most experienced producers. nd Alive was probably the most ccessful such publication so far, and successor How I t Works has a very ofessional feel.

The work takes the paedia of 'invention, chnology', proceeding alphabetically that parts one and two (the traditiondoublesize first issue rip off) get as as Alkaline Earth Metals. Science, course, cannot be treated i n this way ithout plentiful lack o f cohesion, and a way of learning science How It i s pretty much a non-starter. e real interest in How I t Works for mmon freaks must be as a guide to ual things to make or do, and the l i s t contents shows plenty o f useful devicfrom the abacus on out. But here ain the magazine meets identity oblems, this time concerning the tual amount of detail given A fine ample of this is the very second item the book, A-bomb. (And let's in passing, hope that entries by alphabetical order o f abbreviation will be discontinued). This consists of an 0-level Physics coverage of nuclear fission, a lot of history of the bomb and a magnificent photograph of the remains of Nagasaki, but only a few hundred words, less than a third o f the total, on the actual working of the device, 5 0 that yone really wanting to understand, t alone make a bomb would hardly be nearer after reading the feature than re. Even i f the entire bomb feature merely astunt for the press, as i t s r ificial placing in the first issue would gest, it all bodes badly for How It rk's chances as a 'make it' guide. Later in the first two issues things improved, wever, with very informative features n aircraft engines, radio antennae and en accumulators.

It remains t o be seen, then, how useful How It Works will be asa guide to making things, But what competition does it have for the amateur wanting to put a few useful devices together?

Surprisingly little, would seem t o be the answer. The main opposition is the Universal Encyclopaedia of Machines, at about one-twentieth the price, from Paladin. Of course, it's a good deal smaller but wins hands down for directness ani general usefulness. It lacks the quite splendid photographs of How I t Works, but this is probably more than compensated for by the lack of the latter's quite ghastly taste in twee pastel shades for the line diagrams; one colour would have been much preferable.

The content of How It Works is difficult to assess, stuck very badly between detail and background coverage, and between technology and the need to compete with i t s rival A l l About Science, which has now been running nearly a year. Although a book on general science, or on technology, or an early inventions would tell you more about any specific item, it may well be that the finished product will be far more interesting than any or all of these.

The best idea, i n fact, is probably to wait until the last part has appeared, when a series o f books o f bits may well appear, culled from the encyclopaedia.

This could be by far the cheapest and most useful way of getting what you want o f the book unpolluted by biographies of Tycho Brahe or flight control plans of Heathrow.

The amount of energy that can be crammed into a given volume of ice before it explodes spontaneously is limited by the small tensile strength of pure ice. Dreadco scientists have found that they can make safer-or alternatively more powerful-forms of ice explosive by incorporating short-staple carbon fibres as reinforcement.

Studies of the physics of the explosive process revealed that a shock wave travels

IMy cryoballistic friend Daedalus notes with interest the report (Novosti Information Service, 13.3.73) that Russian scientists in the Antarctic have discovered an explosive form of ice which is saturated with bubbles of compressed air. A similar material was prepared some time ago at Dreadco's laboratories, and tested in several applications where conventional explosives were unsuitable in view of the heat and poisonous gases they generate. Small charges inserted into the roots of rotten teeth were used for instant and almost painless extractions, The Dreadco explosive can also be used for extinguishing oil gushers, with far more reliable effect than dynamite. Daedalus points out that the cooling effect of the ice is relatively unimportant cornpared with the Joule-Thomson cooling which occurs when the micro-bubbles of air are explosively-and hence adiabatic-
