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, Another Kleiner Perkins investment

[Eukariote]

EEStor is another interesting electric-car-related Kleiner Perkins investment http://www.businessweek.com/the_thread/dealflow/archives/2005/09/kleiner_perkins_1.html [businessweek.com]. 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 [peswiki.com]. 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The internal combustion engine is obsolete.

Ugly

Why do people insist on making electric cars ugly as hell?

By independent accounts they have been realized. Lockheed Martin for example has taken out a license and confirmed the performance claims that EEStor makes http://gm-volt.com/2008/01/10/lockheed-martin-signs-agreement-with-eestor/ [gm-volt.com]. When the technology will make it to the market is still a bit of an open question. In 2009, supposedly. But given the big vested interests in the oil industry, I would not be surprised if it will be delayed.
