Nanoscale Batteries

"Startup A123Systems Inc. on Wednesday (Nov. 2) unveiled a line of nanoscale, Lithium-based batteries said to deliver up to ten times longer battery life and five times the power gains." InformationWeek

Just imagine having smaller batteries that last longer and can power larger more power hungry devices. My PDA could last weeks potential with the wireless on. My laptop would be lighter and last longer. My MP3 player could be smaller. They could even more easily begin the development or implementation of small probes, robots, pace makers, or other health related technologies to improve our lives. Though this could put a hamper on RadioShack's battery sales.
