Even though using public transportation within a city greatly reduces the overall amount of pollution, this doesn't stop people from demanding cleaner and more efficient means. A new kind of bus being launched in Britain may be able to provide the perfect solution to such demands, as well as bring a halt to the reliance on diesel.
The bus uses the same Mercedes-Benz diesel engine is received from the factory, which is then modified to run on the cleaner burning Bio-methane. Even with the modifications the engine is still able to run on diesel fuel, which it will do about 25% of the time.
The other 75% of the time, the engine will be producing about 50% less tailpipe emissions as compared to its diesel burning cycle. This, combined with the relatively cheap fuel, has raised quite a few eyebrows at the University of East Anglia's (UEA) Low Carbon Innovation Center (LCIC). A substantial portion of the funding for the project came from the LCIC, which has been monitoring the amount of pollution in Norwich since 2005.
The technology will likely be expanded to other cities as soon as the first fleet test is complete.Science Daily
