Uncle Sam and I (and you) are now invested in Tesla Motors. What? That’s right, according to gas2.org, every tax paying American citizen is helping keep one of the slickest green automobiles alive. Tesla Motors announced the $465 million loan from the U.S. Department of Energy in June 2009, and the deal is now official. “This loan will allow us to further accelerate the production of affordable, fuel-efficient electric vehicles,” said Tesla CEO Elon Musk. Production is scheduled to begin by 2011.
