I personally wouldn't count on the "Big Three" actually implementing any of these new technologies in the near future. Of course building a new alternative energy infrastructure would put millions of now unemployed people to work, but why rebuild when your not done wrecking everything.
If the "Big Three auto manufacturers aren't building alternative energy vehicles with the money they're getting from Congress, then what are they doing with it?
I wouldn't be waiting around for alt energy infrastructure and smart electric grids, and I wouldn't wait around for the "Big Three" to actually build a viable automobile that runs solely on electric power. The "Evil Three" go hand in hand with the big oil bankers.
I would however, take a serious look at smaller companies that have developed some very exciting alternative energy technology. Wheego Electric Cars, a division of RTEV, is officially launching its U.S. dealer network. The first car will be the Wheego Whip, which is most certainly not a smart fortwo, and the plan is to find 50 dealers in America who want to sell them.
Wheego has an exciting line of electric cars that I'd like to see on the roads very soon. The following article has more info on these great electric cars:
