Solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels or heating up the kitchen. The first solar cooker we know of was invented by Horace de Saussure, a Swiss naturalist experimenting as early as 1767 Box Cookers - This type of cooker has been the advantage of slow, even cooking of large quantities of food. Variations include slanting the face toward the sun and the number of reflectors. With box cookers, the food will cook more quickly if it is divided into several smaller pots instead of having it all in one large pot. Solar cooking is not only fun but it's a great educational tool. Solar Box Cookers, constructed using cardboard, newspaper, aluminum foil, and a piece of glass will typically cook at temperatures between 225 - 275 F. Panel Cookers - In this design, various flat panels concentrate the sun's rays onto a pot inside a plastic bag or under a glass bowl. The advantage of this design is that they can be built in an hour or so for next to nothing. Panel Cookers require only one box, aluminum foil, a jar and an oven bag, and can be constructed in less than an hour. Parabolic Cookers - These are usually concave disks that focus the light onto the bottom of a pot. The advantage is that foods cook about as fast as on a conventional stove. The disadvantage is that they are complicated to make, they must be focused often to follow the sun, and they can cause burns and eye injury if not used correctly.

A good first food to try is a small quantity of rice, since it is fairly easy to cook and looks very different cooked than it does raw. Chicken or fish is also very easy to cook. There's no need to rotate the oven though it will improve cooking times

A solar cooker is like a hot box, in which we can cook our food without any cooking gas or kerosene, electricity, coal or wood.

THE SOLAR CONSTANT IS THE NUMBER USED TO DESCRIBE THE AMOUNT OF SOLAR RADIATION THAT REACHES THE EARTH FROM THE SUN. IT IS ROUGHLY 1400 w/M2. FROM THE DIAGRAM TO THE RIGHT YOU CAN SEE HOW THE SHAPE OF THE EARTH AND ATMOSPHERIC CONDITIONS LIMIT THE MAXIMUM SOLAR RADIATION AVERAGE TO AROUND 250 W/M2 (WITH HIGHS AROUND 900 W/M2- SEE PREVIOUS PAGE). THIS SPECIFIC ENERGY INPUT IS CRITICAL FOR PLANTS AND ANIMAL HEALTH. AND AS WE KNOW FROM BURNING BUGS WITH MAGNIFYING GLASSES, IF THIS INPUT IS
MAGNIFIED JUST 10X IT IS ENOUGH TO COOK PLANT AND ANIMAL FLESH. SOLAR COOKING IS THE RELATIONSHIP BETWEEEN THESE TWO VALUES, BETWEEN THOSE WHO LIVE IN THE SUN AND THOSE WHO ARE COOKED IN THE SUN.

A solar cooker, or solar oven, is a device which concentrates sunlight for use as a heat source. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide to help reduce fuel costs for low-income people, reduce air pollution and slow deforestation and desertification, caused by use of firewood for cooking. Solar cookers are a form of outdoor cooking and are often used in situations where minimal fuel consumption is important, or the danger of accidental fires is high.

historical practice
COLLASUS/COOLSURF/SOLAR COOKING
Carry over cooking refers to the phenomenon that food retains heat and continues to cook even after being removed from the source of heat. The larger and denser the object being heated the greater the amount of carry over cooking. After being removed from the heat source (oven, barbecue grill, etc.) the internal temperature can continue to increase. This means that when cooking large roasts or turkeys, for instance, the roast meat should be rested before serving to allow heat to distribute from the warmer outside to the cooler middle, also allowing juices to distribute throughout the meat.

This is a rather unique method of obtaining fire. At first thought it sounds just as implausible as the “fire from water” method. But after some thought, it becomes obvious how to proceed. However, there are many issues to overcome in actually getting a fire using this method! It’s not as easy as it might seem.

etc... ABOUT COLLASUS we are a collective of young architects, planners, sculptors, painters, web designers, graphic designers, photographers and farmers. We are interested in projects that propose solutions for the future we want to live in. The ethos of the collective is two fold: to seek sustainability in every sense of the term and to explore the nature of collaboration. ABOUT COol_surf Cool_surf is the diagramming of the flux of information in contemporary media. The objective of coolsurf is to make ‘sense’ of and catalogue the endless array of information and images that we encounter in surfing the web. Cool_Surf is created by the process of making simple “screen captures” and organizing them in a book format that creates a set of logical connections between the websites one visits. Cool_Surf is made into a book format to re-contextualise, catalogue, map and issue this information. Some of the most useful subjects for Cool_Surf are those that will be valuable as resources for people without access to the Internet. look for more diy farm coolsurfs: 2 oil 3 composting 4 DIY waste management 5 recycling plastics
