For years I’ve wanted to find a way to power a small battery (particularly for a heart pacemaker) without having to change the battery or to plug in.
It appears that Nokia is coming close to doing just that with some of their cell phones. If it works, this would be a great breakthrough (and I can stop dreaming about being that great inventor who saves the world!!).
