Kim Gu-Han of Universitat Dulsburg-Essen, Germany, wants to build a solar-powered car that can charge itself entirely from the sun. The problem is the limited space for photovoltaic panels on a car’s roof. The Helios overcomes that limitation by acting like a frill-neck lizard. When stationary, the off-road vehicle can unfurl a large set of photovoltaic cells to produce enough energy to run the car, with excess energy for home power. The Helios won Best Use of Technology category at the Interior Motives Design Awards 2008.
