It's better but no the best. An Electric motor efficiency is in the mid 90's% so you can't ask for much better there. Transmission losses seem to top out around 15%, so again you can't ask for much improvement there. Batteries in the new generation electric cars are no longer lead acid. They are either li-ion or ni-MH. Huge advances have been made in li-ion eliminating the overheating/fire issues and both are very safe and pretty much harmless now Wind can not solve all of our problems as the wind is not always blowing. It has to be coupled with another system. <br><br>Doing research first is usually quite helpfulanonymousFri, 06 Jul 2007 21:30:57 -0000
