www.chinabuses.org: As the Shanghai 2010 World Expo approaching, Shanghai government unveils new environmental-friendly buses. The buses are powered by 360 ultra-capacitors and are charged at bus stops with equipment attached to the roof of each vehicle. Each charge takes only 30 seconds and can power the bus for 3 to 8 kilometers. Experts say the buses don't have any emissions.

The new electric buses represent the city's first step to upgrade buses that either cause air pollution or damage the image of Shanghai. Ma Xingfa, an official of the Shanghai Science and Technology Commission says "The new trolley bus is a win-win solution for new transport." According to the plan, the science commission has teamed up with a total of eight high-tech and transport companies to develop new buses. Each bus costs about 800,000 yuan.
