Honda hydrogen cars hit the road

The first time I read about the potential to build a hydrogen powered car, one that was to emit water vapour as its exhaust fume, I was ecstatic. Obviously, we were only a decade or so away from the flying Delorian, and you all know what that means... hoverboards!Seriously though, it was a beautiful image, to have a car that runs normally and the only mark you leave on the environment is water.
