A non-polluting hydrogen-powered automobile developed over 14 yews may welk he the vehicle that its inventor Gus Ehrenberg, an engineering graduate from the California Institute of Technology and now an octogenarian, dreamt of.

The automobile has potential use as a family vehicle with a range of more than 240 kin on the hydrogen energy equivalent of 3.79 litre (I gallon) of gasoline (Hydrogen Today, Vol 6, No 1).

The vehicle uses a series-wound electric motor for each wheel which permits generation of electricity during braking or down-hill motion. The energy can then be stored in a flywheel and used for acceleration or up-hill climbs. A fuel cell can be used for primary electricity production.
