Now this is a smart idea for those people who feel that their hybrid car lifestyle just isn't good enough for the environment.
The SEV solar module for 2004-2006 Toyota Prius cars generates 215 watts of power which the makers claim provides up to an extra 20 miles of gas-free travel a day and a 29% better fuel economy overall.
They claim it will pay for itself in 2 to 3 years, but only if you take liberties with a Federal energy tax credit by buying it at the same time as a residential solar system and conveniently include the price in with your residential system.
