Well we've all heard about the future of hydrogen cars (remember Arnold's hummer) and that fuel-cell motorcycle that was supposed to be available last year. But now a company called Valeswood Environmental Technology Developement has unveiled a hydrogen bicycle. The bike is supposedly available in the UK for around 700 pounds, but I haven't been able to find it for sale online. Tony Bosworth from Treehugger.com had this to say about it, "We all know pedal power can make you fitter but if you opt for this hydrogen-powered bike you could also be making the planet a lot fitter too." Umm, wait, isn't riding a bicycle that doesn't use any fuel even better for the planet? And didn't we conclude that hydrogen is dangerous?
