Venture Capitalism To the Rescue
theodp writes "Al Gore, Bill Joy, and a Norwegian cutie — a TH!NK open electric car — grace the cover of the latest NYT Magazine, which asks: Can the venture capitalists at Kleiner Perkins reduce our dependence on oil, help stop global warming, and make a lot of money at the same time? While Kleiner Perkins — which funded Genentech, Netscape, Google and others — has a number of other green-tech bets, a partner says its goal is 'to make a lot of money for our investors,' not to save the environment."
EEStor is another interesting electric-car-related Kleiner Perkins investment http://www.businessweek.com/the_thread/dealflow/archives/2005/09/kleiner_perkins_1.html. They have patented technology for super capacitors with over ten times the energy density of lead acid batteries. Being capacitors without electrochemistry, the power density (charge/discharge rates) is also very high.
The trick is that they use a doped barium titanate dielectric with a very high permittivity structured as a sub-micron grain composite interspersed with thin Aluminum oxide and glass layers to lower the breakdown voltage. http://peswiki.com/index.php/Directory:EEStor. The big gain over normal capacitors happens because the energy content of a capacitor goes as the voltage square, and the overall relative permittivity exceeds 10000.
The internal combustion engine is obsolete.
