Oh, you mean, braking.]]>Feb 8th 2008 9:04AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/
I think it's a brilliant idea. Gives you some extra exercise, and possibly decreases the shock on your knee itself while you're at it. ]]>Feb 8th 2008 10:05AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 11:45AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/

Well for the little I know about phisics spending 1 watt to harvest 1 watt is as close to perfection as you can get without calling upon other God's blessings such as solar energy and such and if they can make it small enough to disappear under the clothes well, I'd rather getting free energy anytime I need it by doing a little more fitness in secrecy than having it only in bright sunlight and dragging around one of those weird looking solarcell bags or stuff like that ;P]]>Feb 8th 2008 9:42AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/
Now assuming you're reset stride is 1 second, then 1 Watt would create 1 Joule of energy. (the math is difficult in this one) So say an average person takes 2000 steps a day. (Anyone with pedometer experience have any better numbers, I really have no idea) that's 2 KJ of energy that either would have been wasted or helped with your corpulence.]]>Feb 8th 2008 10:41AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 12:01PMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 9:56AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/

The human body's natural bioelectrical power plant is far far more efficient than anything human technology has ever made. To convert power from that, with perfect efficiency, is amazing.

But hey, who am I to challenge your writers. I'm sure you know best - and that we should be working on breaking that whole trivial conservation-of-energy thing. Or we can just keep dumping alkali metals into our landfills. Yeah, that sounds like a better idea.]]>Feb 8th 2008 10:23AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 11:19AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 11:52AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 10:26AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 10:34AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/A much wearable solution might come from an "inertia only device" accomodated in the shoes or in a pocket of the throusers... It would be far less effective than actively collecting the labor from the articulation but again, I'd prefer a little something that I would wear than a no-matter-how-powerful alternative that I would let home most of the times.]]>Feb 8th 2008 11:06AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 11:38AMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/

Kick = voltage = electrical charge = impulses sent to kick... Nice little feedback loop that might yield a small overall extra electricity, and you get a workout... :-P]]>Mar 21st 2008 1:59PMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/Feb 8th 2008 3:15PMhttp://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://www.engadget.com/2008/02/08/electricity-generating-knee-brace-fails-the-american-dream/http://fas.sfu.ca/newsitems/energy-harvester]]>Feb 9th 2008 4:35PM
