Buses Go Green: Fuel Cells Pave the Way for Zero-Emission Transportation
Traffic volume is expected to double by 2010, so making buses more environmentally friendly is crucial. The main ways to do this are by using better energy conversion techniques and developing non-fossil fuel sources. Technologies like diesel engines, natural gas engines, electric buses, wheel-hub drives, hybrid drives, and fuel cells are being explored to achieve this goal. Fuel cells are seen as the future of bus transportation.
