London's New Buses Run on Hydrogen
London’s famous red buses are going green. The city has introduced eight buses that are powered by hydrogen. The vehicles have fuel cells, batteries that produce electricity and emit only water vapor.
The new buses have cost the London city council over $ 30 million. There is one fuel station in the city where the buses can be recharged. By introducing these new buses, London plans to reduce its carbon footprint as the 2012 Olympics approach.
If the project is successful there are even plans of turning London’s famous taxis into green vehicles as well.
