Solar-Powered Toyota

Steve Lapp, Canadian and energy efficient car collector, has thrown together a solor-powered Toyota Prius. His design has improved the fuel economy by 10%, which is almost two times better than Honda and the redesigned Civic engine. Lapp is predicting another increase of at least 10% with the 270 watts. The unfortunate feature is the cost of design. Solar panels are expensive and it would take driving the car at least 500,000 miles before just the solar panel s paid themselves off. Good luck trying to get the car to last that long.
