Here is an interesting project:
"The Nimbus by Eduardo Galvanis has four driving modes for four different kinds of trips: the energy saver for city driving, standard mode, faster cruise and four-wheel drive. Its electrical engine works parallel to a micro combustion generator to recharge its own lithium-ion batteries, and part of the exterior is covered in solar cells. A regenerative brake mechanism enables the car to capture and convert kinetic energy for additional power."
