The first-place winner of architecture magazine eVolo's 2010 Skyscraper Competition, LO2P consists of a ring of greenhouses surrounding a giant turbine and particle collector. The building, made from recycled cars, would suck pollutants out of Delhi's increasingly filthy skies and spit out waste products to be turned into biofuels. It is the vision of French firm Atelier CMJN.
Stupefaction Factor: 6. This would be just like one of those infomercial home air purifiers, except instead of inhaling all of your cat's dander, it would produce breathable air for the residents of one of the world's most polluted cities.
Fantasy Factor: 8. There are plenty of systems already in existence that use plants to purify air and water. None of those systems require an enormous whirling blade operating 24/7 in the middle of a massive population center.
