The ideal situation would be to have a network of high-power electric charging stations, which would allow you to juice up your electric vehicle on the road much as people fuel up their gas guzzlers today. Ceder and Kang estimate that an 180-kilowatt power source could give a full charge to the typical plug-in car's 15-kilowatt-hour battery in five minutes.For school buses, with dedicated, regular runs, this probably wouldn't be as much of a problem. According to Scientific American story on the same report, the batteries would also be cheaper. This, coupled with increased production, would likely drive down vehicle costs. [On a side note, for willing to dirty their hands with the coments from the peanut gallery, comments below on the MSNBC story have a fascinating discussion of the real "greeness" of hybrid technology.]
