Martin Eberhard of Tesla Motors gave an excellent talk tonight at vlab. These electric cars are the future. He should put up his slides comparing the various ways to power a car and their efficiency. It's *very* convincing. I remember visiting the tesla website several months back and seeing a cool new gadget, but what was missing was the punch that Martin gave tonight (that these electric cars are *so* much more efficient than all the alternatives). Another nice tidbit is that lithium ion batteries have improved in efficiency by 8% each year for the last 20 years and there's no reason to see this trend stop in the next 10 years. (another data point for the technological singularity)
