This has already been discussed here. The company received it's initial government funding during the Bush administration. Supporting the development and manufacture of advanced batteries suitable for the automotive industry has been a bipartisan endeavor. It's too bad this company failed because the US is rapidly falling behind in this market.

I am surprised Romney did not bring this up since it happened on the day of the debate. Your stimulus dollars hard at work.
