Gasoline is not dead car companies just need to try harder might be time for manufacturer subsidies. <a href="http://www.FliteRecord.com" rel="nofollow">www.FliteRecord.com</a>Eric WilliamsTue, 29 Jul 2008 12:59:16 -0000http://ecotechdaily.com/2008/05/24/high-tech-horsepower-makes-up-for-shrinking-engines/#comment-1171906That's really cool. When I was in mechanical engineering student in college I designed turbocharger that was coupled to an electric motor through a centrifugal clutch for faster spin up. Of course, that was in Texas in the 80's and gas was about 65 cents / gallon so I wasn't really motivated by economy. I was going for negligible turbo lag. The clutch mechanism was a real pain (and probably not really feasible because of the rpm involved). It never occurred to me to just use a second compressor in serial...Jim S.Sat, 24 May 2008 12:08:25 -0000
