Chinese claim to have developed an oxygen emitting green car concept

Chinese automaker SAIC have developed a new green car, called the ‘Leaf Concept’ to be showcased in the upcoming Beijing Motor Show. This car is supposed to be powered by using a solar panel placed on its roof and in-wheel turbines using wind energy. Although, there is no information as to how it will happen, but SAIC claims that the solar panel will also emit oxygen in the process. However, physicists seem to have major concerns regarding the practical usability of this car. According to them the size of the solar roof panel is not big enough to generate sufficient power for the car. They also say that according to the law of conservation of energy, the in-wheel turbines will create more drag than the power they produce.

Although the idea is very environment friendly, it would have been more useful had it been equally practical.
