This whole idea of spreading the energy from one source out to as many things possible has always fascinated me. I suppose this goes back to the things I've learned as a child, like leaving your oven open after you've cooked something so the oven can be a heat source for the room as it cools down.
But who would have thought the energy from walking could also be used to charge a cell phone?
I first read about this on
BBC News.
They say the adapted knee brace called Knee Dynamo can generate enough energy to power a mobile phone for 30 minutes from
one minute of walking.
It looks real clunky now, but after some time with development, it could not be detected on your leg. In the article, they mentioned t
he first to benefit could be amputees who are being fitted with increasingly sophisticated prosthetics.
So, there's medical research behind it, I'm sure. But appealing to a mass market would be great. Then my Blackberry would never get a low battery now if I have my Knee Dynamos on.
