Solar headlights on the electric Audi

Members of the Georgia Tech Solar Jackets replaced the engine of an Audi TT with a solar electric drivetrain that offers a mileage 70 miles and retains the TT’s all-wheel drive. They call the car a solar-assist electric vehicle. The top of the car is covered with sheets of thin-film photovoltaic laminate covers. The solar array provides 12 volts of power to the windows, stereo, power brakes, steering and lighting. Any leftovers are stored in the car’s 120-volt battery pack. When you open the gas cap, you can pull out the cord and charge it using any outlet of your house. The team hopes to double the car’s range to 140 miles after installing a Lithium-ion battery later this summer.
