I’ve long thought that solar panels need to be used all over in order to alleviate strain on an energy grid, and now that seems to be happening. Solatec has created a kit that you can put on a Toyota Prius to charge it while the car is sitting in the sun.
It can improve the milage up to 10% according to Toyota. The company is still testing the product, but I hope to see solar panels integrated into all cars.
