As much talk about Google building driverless cars, I am more impressed by the idea of solar roadways. The video may be a little silly, but the ideas are fantastic.
The information that it enables, the future savings it offers, the positive impact on the environment, could be enormous. Of course the cost to rebuild every road in America would be enormous and take a lifetime to complete. But ultimately it would make driverless cars a much more realistic next step. So sit back and enjoy.
