If you watch this video footage, from GigaOM TV’s latest episode of Green Overdrive, you might be surprised to see who’s driving the neon green electric race car soaring around the track at the Mazda Raceway. It’s Tim Collins, 70-year-old investment banker, and founder of Kleenspeed, a startup that’s using electric race cars to test technology that will eventually be used for a passenger car. The company, founded in 2007, works out of NASA Ames Research Center in Mountain View Calif., and won the time trials at the raceway earlier this month, breaking last year’s record. Check out Green Overdrive, because if it’s green we’ll drive it.
