A former director of engineering at Ford Motor Company says there is no need to wait for clean power. His Hydrogen Engine Center introduced the first hydrogen-fueled combustion engine for industrial uses in 2004. The company’s niche right now includes airport ground vehicles, forklifts and the like. (American Airlines alone has 9,500 vehicles likely to be converted to alternative fuels over the next decade.) His engines can "run on a number of fuels including hydrogen, ethanol, natural gas, propane or digester gas from landfills," the AP reports. We will be breathing cleaner air in the future thanks to the enthusiasm of Ted Hollinger and his team.
