P R E V I E W C L I P: An alphabet of new terminology has evolved over the past decade to describe the gasoline inventions fueling the next generation of land and ocean travel. DNGVs (dedicated natural gas vehicles) are already on the road, along with vehicles with Flexible-Fuel tank design for blended fuels. HEVs (hybrid electric vehicle) utilize two different energy sources for efficiency. The invention of the fuel cell, an electrochemical engine, has revolutionized our concept of how we can ecologically and economically travel in the near future. http://www.ssrvideo.com/
