Lots of Progress on Electric Cars


Lighter Cars and Electrification will Reduce Oil Demand

Toyota and others are working on 600kg cars instead of 1000kg. Cheaper titanium, more carbon fiber and other materials.

Steel accounts for about three-quarters of the average car weight in Japan of around 1,350 kg (2,976 lbs). Using carbon fiber to replace steel in key parts could cut vehicle weight by up to 40%, to slightly above an average 800 kg (1,800 lbs). This could improve fuel efficiency and reduce carbon dioxide by approximately 30% per car.

China's BYD has started selling its plugin hybrid electric car in
China for US$21,000.

EEStor's ultracapacitor patent details. They are supposed to be having commercial rollout in 2009.

A lot of better battery and ultracapacitor tech...sufficient for many planned needs for storage it is a matter of cost and scaling up for sufficient industrial impact.
