Hydrogen IC Engine

DaimlerChrysler, GM, Honda, and Toyota are in the process of placing both IC and fuel cell units into the hands of ordinary drivers to gain experience and to collect data. Their prototype units cost about 1 million each. The manufacturers aim for a pilot commercialization phase by 2010-2012 at a unit cost of 250,000. They expect full production by 2013 at a unit cost of 50,000, and this cost will drop as the volume of production increases. 

Hydrogen buses operate in Montreal and Bavaria, an H2-powered passenger ship sails in Italy, and the 2008 Olympics in Beijing featured hydrogen vehicles. Russia has flown a jet, fueled partly by hydrogen. In the United States, the Defense Advanced Research Project Agency (DARPA), NASA, and the Air Force are jointly developing an Earth-orbit airplane fueled by 

Two teams (in Turin and Madrid) are converting two light planes so that they can use hybrid fuel cell-battery electric engines.
