More than half of General Motors' 2009 patent filings were for green tech

Over the years, General Motors has not often been seen as a forward-thinking company when it comes to green technologies. Sure, the Chevrolet Chevette was one of the first American cars to crack the 30 miles per gallon mark (the diesel model got north of 50 mpg). True, the EV-1 experiment showed some promising results (or, depending on who you ask, helped kill the electric car).

Inventor may have $12 billion dollar claim against GM

Twelve years ago, Jack Evans (founder and namesake of Evans Cooling) went to court with the claim that General Motors stole his design for a reverse-flow cooling system, a setup that was later put into production in GM's LT1 series of small-block V8s - and a design that was protected by Evan's patents. Such a cooling system sends cold water from the radiator directly to the heads and then to the block, which is opposite of a conventional arrangement. While it potentially offers a incre
