RE: New engine drastically improves driving range and cuts emissions.
While that video was uploaded to YouTube back in October 2009, the researchers have completed their prototype, unveiled it at an ARPA-E conference last week, and have already been awarded the $2.5 million funding.
@marvinlee: Herrman and Nguyen's article awkwardly restated the researchers' claim concerning weight: "The generator ... will replace nearly 1,000 lbs. of engine, transmission, cooling system, emissions, and fluids " (see project's PDF on arpa-e.energy.gov site).
