I kind of like the reference to electric truck posted by syzygys. I quote : " More than half of the truck's cost is the battery, in part because A123 basically hand builds each one now, and Terblanche expects that cost to come down dramatically. A123 is building a battery factory in Michigan with the help of a $249 million manufacturing grant from the Department of Energy. When that gets up and running, as early as later this year, Navistar expects battery prices to fall and, with it, the cost of the truck." Which is what I have been saying all along. We can expect evs to be exactly the same as computers, flat screen TVs, and all other electrical goods. They will begin expensive, and over time, will become cheaper and better. The time scale I project is 10 to 20 years. At the end of that time, evs will quite likely outnumber petrol and diesel vehicles on the road.
