BUILDING THE CITY OF THE FUTURE
By 2020, the world population will be 9 billion and 75 per cent of us will live in cities, many of which are creaking under the strain. The perfect metropolis remains science fiction – but innovative designs are transforming urban living. Ianthe Butt tracks down the best. Illustrations by Patrick Morgan
LIMA WATER-PRODUCING BILLBOARDS The desert city of Lima is one of the driest in the world (second only to Cairo). Annual precipitation is less than 2cm, but the atmospheric humidity averages 83 per cent. Peru’s University of Engineering and Technology and ad agency Mayo Draftfcb have created the world’s first advertising billboard, which condenses moisture in the air into drinking water. The billboard houses an internal reverse osmosis filtration system: air passes through a filter on the side of the billboard and into a condenser, producing water, which is then purified and collected in a tank with taps. draftfcb.com
COPENHAGEN INSTANT CYCLE LANES Separating cycle lanes with a kerb – or at a different level to the road – decreases accidents and encourages cycling. Many cities, however, are still reluctant to invest in costly permanent cycle tracks. Enter the Copenhagenize Flow. These pre-fabricated recycled tiles click together to create an inexpensive, easyto-implement and effective temporary cycle track system. Up to a kilometre can be laid in a day by a small team, at a tenth of the cost of a permanent structure. copenhagenize.eu

THE NETHERLANDS AUTO-DIMMING STREETLAMPS
MELBOURNE DIGITALLY CONNECTED URBAN FORESTS
Why do streetlamps burn so brightly when no one is there to see them? This question is one Tvilight BV addresses with its dimmable streetlamps. Containing a wireless sensor module, during off-peak hours, lamps dim to a lower level. When a car, pedestrian or cyclist nears the lamp, the brightness increases to its maximum level. Light pollution is reduced, up to 80 per cent of energy is saved and carbon dioxide emissions are lower. The antithesis of a dim idea. tvilight.com
One proposed solution to drought and rising temperatures in Melbourne is to increase the city’s green canopy coverage from 20 per cent to 40 per cent by 2040. It is hoped that this increase will lower summertime temperatures by 4ºC. ‘There is an online interactive map of all trees in the city,’ says Carlo Ratti, director of the Massachusetts Institute of Technology’s Senseable City Lab. We’d love to see more cities branching out with green initiatives. melbourneurbanforestvisual.com.au
BERLIN CARSHARING WITH ELECTRIC, FOLDABLE CARS Carsharing allows cities to keep up with public transit demands, while helping to combat congestion and pollution, says Boyd Cohen, urban and climate strategist. ‘Twelve to 20 cars are taken off the roads for every vehicle added to a carsharing system.’ Berlin is already home to eight carsharing companies, and now national rail company Deutsche Bahn is piloting its own carsharing programme with Hiriko’s folding electronic cars. ‘These occupy much less valuable space when parked,’ says Cohen. hiriko.com
NEW YORK THE LANDFILL SOLAR ENERGY SITE Michael Bloomberg, the former Mayor of New York City, is set to convert 47 acres of landfill in Freshkills Park on Staten Island into the city’s largest solar-energy facility. It’s great to see a site like this being transformed into a showcase for urban renewal and sustainability. Once completed, it will produce up to 10 megawatts of power, enough for 2,000 homes. Operated by SunEdison, the site will increase New York’s renewable energy capacity by 50 per cent.
