The Helios Concept was the winner in the Best Use of Technology category at the Interior Motives Design Awards 2008.
It was designed by Kim Gu-Han from Universität Duisburg-Essen – Germany.
The Helios is an electric off-road vehicle use powered by solar energy.
To increase the surface area of the photovoltaic panels, when not in motion the upper surface of the car transform into a large "fan" with four wings to store more energy or to serve as an energy station.
This transformable design was inspired by natural evolution – some animals have developed a stretchable skin to absorb more sunlight.
