buses the best way to clean up a city's air? Londoners
might someday have some kind of answer to that question because the city government is investing a lot of money in hydrogen-powered vehicles, with the iconic red double-decker buses some of the first to be run on the new technology. The first three hydrogen buses are on the RV1 route, according to the Guardian UK
, and look just like standard buses except for a sticker noting the power source. Oh, and they sound, "barely louder than a milk float" according to the paper. A dozen buses will soon be converted and become the cities hydrogen test fleet. If all goes well, the entire fleet could switch in about ten years.
More details and a debate on whether this conversion is actually a good idea at the link.
