walking energy generator Let's face it: every time your cellphone battery runs empty you feel amputated and you quickly run back to your house to connect to a powering-adapter. Bionic Power Inc. is now developing a knee-brace that can be used to charge small devices; the 5-watt electricity output from one knee generator is enough to power 10 cellphones at once.

    Crappy, yes. It looks like they've just invented the pacemaker. And in order to be worn, it must be nihilised and sexified first. But this device makes me wonder: if the knee can be used to harvest biomechanical energy, what of the shoes or the arms? And what about sitting after one gets tired? I can imagine a bench in the park that could generate energy when people sit down on it... and perhaps a whole range of clothes taking care of powering devices we carry with us. By the way – the article at http://NewsScientistTech.com links to another project (the bouncy backpack) capable of generating power from walking (it looks crappy too) :)

  • When I first saw it I thought it was a crap product, since I am glad that I just got rid of the dynamo on my bike and I surely don't want to make walking more difficult in order to power my cellphone! But while watching the movie I learned the researchers had already though of this and generate the energy during the braking phase of a walk. It uses the energy your body wastes! How is that for being 'green' ?
