"First Solar Power Car - July 2004 marked the 20th anniversary since Greg Johanson and Joel Davidson set The First Guinness World Record for a 100% solar powered car. In 1984 the solar electric vehicle was retired and taken apart, but the solar array is still producing electricity for an off-grid home. To transport the solar electric vehicle, we modified a boat trailer by extending the frame 5 feet (1.5 m) and adding a plywood deck to which Sunrunner was strapped. Also on the deck were 16 golf cart type deep cycle batteries and a 2500 watt inverter. The combined solar vehicle array and trailer provided approximately 5 kWh/day of electricity with 16 kWh battery storage for loads up to 2.5 kW. The batteries and the inverter were not a part of the solar powered car, but were used for demonstrations. During 1984 and 1985, we had an open invitation to race any other solar powered car on land or in the air, but no one accepted our challenge. By 1986, a few other people had gotten into the fun of solar power car activities. Peter Rubie had an aborted attempt at a cross-country run. Art Boyt made a cross-country run, although his vehicle used battery storage. In Europe, Mercedes Benz spent a lot of money to build a racer. The solar electric car craze had caught on."  We doing a really  a good job coming with good invention but American people need to keep buying to transition to solar power. So keep on buying and buying Solar energy. If want to have a future we need to start now!
