It has become a new age all together and the green revolution seems to be taking over inch by inch. A decade back, it was hard to even generate little power using alternative sources of energy and here you have cars, which run on solar power. A few automobile companies have spent a lot of their earnings in research and development to build cars, which can optimally run on the road, not by using petrol or diesel but wind. This is an achievement by itself and has taken quite a lot of work and talent behind to see that it is a success.
The technology is such that the solar powers are absorbed by the solar panels, very artistically camouflaged on the car exterior. Once absorbed, transformed and stored into a rechargeable batteries. In this case, even while the sun is not out, the car would run on the charged up battery.
