Now That's Some Leg Room In early October, London's Trafalgar
Square was host to the Microcab, an ultralight hydrogen-powered
taxi designed for inner cities. The futuristic vehicle seats
four, has a maximum speed of 30 mph, and gets about 150 miles to
the gallon of hydrogen. Its only emission is water vapor, and,
unlike hybrid cars, it's powered entirely by a fuel cell. "With
the scare over oil shortages and rising fuel costs, it's
definitely a question of when, not if, we need to find
alternative fuels," says John Jostins, the inventor of the
Microcab. He hopes to launch Microcab programs around the U.K.
