While attention has been focused on developing pollution-free hydrogen-powered cars, Intelligent Energy and some others have turned instead to two-wheeled transportation. The firm, which is relocating to Los Angeles from London, says the motorcycle’s fuel cell develops the equivalent of eight horsepower, good for speeds up to 50 miles an hour. The cycle has a range of about 100 miles on a tank of fuel. Currently, a hydrogen fill-up would cost about $3, says the cycle’s project director, Andy Eggleston. Link.
