This is the second time of talking about this interesting topic this month, because my electric car gave me a suprise yesterday. I had a short trip by driving my car yeasterday. The place we visited only has one road to get which meandera in a montain. I thought that it will be a challenge for an electric car, but as a consequence, we got the destination very easily. When I check the dash board, it showed that it just spent 1.0 litre gas per 100 kilometres (actually my car is a hybird car). It was a big suprise! When my car went downslope, it would be charged by the gravity, when it went a upslope, the electricity would powered my car. The computer systerm in my car is really good at using any power both from gas and nature. You know that when you step the brake pedal in a moving gas powered car, the extra energy from burning gas will be spread into air , even causes air pollution. But for a hybird car, the energy will be collected and stored in the battery. The efficiency of using the extra energy for a hybird car can be around 40%, But for a gas powered car, all the extra energy wastes.So, who is better?
