Are you guys nuts? An invention like this, with improvements, has the potential to remove the need to charge anything in the first place! All electronic devices would "self-charge" by grabbing power directly from the environment. Essentially, its a minaturized version of those Seiko kinetic watches that never need to be wound up or have their batteries replaced (cause they don't have one)]]>Apr 11th 2007 2:48AMhttp://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/http://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/Apr 11th 2007 3:34AMhttp://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/http://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/
Given the size of the devices, a device could derive energy in a number of ways. Don't know why you are suddenly singling out blood flow as the only mechanical source of energy.

Secondly, they are not talking about mechanical hearts here. The amount of energy needed to power something as large as a human heart is clearly enormous, and something that may not be practical for an implanted generators. But can these generators power an artificial ear? How about an implant that helps control epileptic seizures or Parkinson's tremors? Or a pacemaker that only occasionally sends out electric signals to keep a heart beating regularly?

No need to automatically come up with an impractical example for using this technology is all I'm saying.]]>Apr 11th 2007 3:46AMhttp://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/http://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/
If you want to talk about mechanical energy sources, you will never get "perpetual motion" in a living person b/c we are always putting energy into the system (food). These devices could be implanted intramuscularly, where they harvest energy from myofibril contraction. This process is (largely ) ATP driven, and as long as you are still eating, you aren't getting energy generation.

See glycolysis and the TCA cycle.]]>Apr 11th 2007 9:40AMhttp://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/http://www.engadget.com/2007/04/11/georgia-tech-researchers-develop-environmentally-powered-nanogen/Thanks.
