Solar Electric Cars

I live in California, where there are many sunny days every year. During the summer, when the sun is out, many drivers seek out the shade. But what if cars had solar panels... sitting in the sun, while your at work... or shopping... means your cars batteries were getting charged. Or on those hour long drives, your battery was getting charged as you sit on the highway in traffic. This would also be possible in many parts of the US and world.

We are not too far from being at a point where this might be possible. Today we have reliable hybrid technology, gasoline-electric... all we need to do is add the solar to the equation. Solar panels to the top of the car... connected to the battery... providing a constant charge. For a time until battery technology improves, we would keep the gasoline component for reliability.

I haven't read much about any car makers exploring the use of solar. I hope they are... solar is clean and unlimited.
