Sunlight into electrical energy, so that car pulled up. This car is the Solar Car. Solar cells based on semiconductor materials used in different, often divided into the silicon cells, CdS cells, GaAs cells, among which is the most commonly used silicon solar cells. Because he does not use fossil fuels, so this car is very environmentally friendly.
* Fuel cell vehicles is the hydrogen and methanol fuel, generate electricity through chemical reactions, relying on motor vehicles. The battery power is through chemical reaction of hydrogen and oxygen directly into electrical energy. This chemical reaction does not produce harmful products, it is pollution-free automobile fuel cell vehicles.
* Car is to use air power as an energy carrier of air needed to move their cars when the compressed air released from the drive to start the motor driving the car.
应该是了

4楼的回答貌似是自己写的,不过第三段应该是
Air powered cars use air power as an energy carrier, the compressed air are released inorder to start the engine when starting.

Solar energy, that will become car started up. This car is a solar car. Solar battery according to different, often divided semiconductor silicon, cadmium sulphide batteries, gallium arsenide batteries etc, which are the most commonly used is silicon solar cells. Because he doesn't use of fossil fuels, so this kind of car is environmental protection.
Fuel-cell cars refers to hydrogen and methanol fuel, through chemical reaction to produce electricity, rely on motor drive car. The battery power is through the chemistry of the hydrogen and oxygen, directly into electricity. The chemical reaction process not harmful products, thus fuel-cell vehicles is pollution-free cars.
Air force air as the car is using energy carrier, need to start the car will be released when compressed air start the motor drive cars.
