Vincent Callebaut’s Lilypad City
Belgian architect Vincent Callebaut is an award-winning designer with varied projects. This one, entitled The Lilypad, is nothing short of amazing. It’s an eco-city, floating on water, with the ability to accommodate upwards of 50,000 people. If built as designed, this structure (which uses most, if not all, available environmental technologies) would sustainably produce more power than it would consume.
