As solar power has matured as a technology, companies have started applying it to more than just houses. Acting as an energy platform for our transport was an obvious application.
Solar: Will It Ever Power Our Vehicles
As an active technology, one of the first uses for solar power was on NASA spacecraft. Although not used for propelling the crafts, interested parties immediately started thinking about using solar power for getting us around in our daily lives. Alas, there were so many problems with the technology, including efficiency issues, that the idea never really gained much footing. With the massive popularity of hybrid vehicles, companies and research institutes are revisiting the idea.
Vehicles getting all of their energy from the sun are not a viable option at this time or for the near future. The problem is you simply cant produce enough energy to meet the power needs. Until technology is developed to make the sunlight conversion process much more efficient, there really is not an answer to the problem. This technological advance, however, may not be far away.
