Assuming this story is true, it's fascinating and could be a preview of our future. Apparently, the Chinese have made an electric car (for $5500 no less) that is completely solar powered. The solar panels on the roof require 30 hours of sunlight to fully charge the car, giving it a range of 150 km. Of course, you'll need a few days to actually get 30 hours of sun, but keep in mind that this works out to an hour of full sun buying you 5 km of power. This is free car power.
Add a plug-in option, build the panels into the car body and keep updating the solar panels and electric motors as they get more efficient and this could be the future of short distance urban driving.
