Why Warren Buffett is investing in electric car company BYD - Apr. 13, 2009

Tony Karrer Delicious EVdriven

MidAmericans David Sokol, BYDs Wang, and company advisor Li Lu flew with Sokol from Detroit to Omaha so that Wang could meet Buffett in person. By about 2000, BYD had become one of the worlds largest manufacturers of cellphone batteries. The E6 will hit the Chinese market later this year. Electric cars will be one answer.
