Solar Panels and Cars.

I think that when they have the technology, they should make one of those shades you put in your car windshield when you park in the sun on a hot day a solar panel, so it would help keep your car cool and help power the car at the same time. But it would have to be unplug-able so you could take it out of your windshield when you were driving.

Just a thought,
