Bit of "social interest" investing on the part of Uncle Sam
Unlikely that there will be any breakthroughs here.
Betting on "nubie" companies with virtually no experience in volume manufacturing or distribution
A Long Bet on Electric Cars - BusinessWeek:
"Not every government investment is a sure bet. The question is how much risk taxpayers should shoulder. The feds have put $465 million into Tesla, but it has raised only $300 million and change in private capital. And the U.S. has invested five times as much in Fisker as private investors. Rogers says Fisker must raise more money to tap the credit line, but debt will still account for 70% of the company's funding. So the risk, and burden if these companies fail, will mostly rest with U.S. taxpayers."
