Nokia hopes to one-up Touchstone, harness wireless power for "ambient" phone charging


Like a page torn right out of the government's top secret files on Nikola Tesla, a Nokia research team is working on a wireless energy harvesting mechanism, which sucks up all that cancer-giving RF floating through the air and turns it into electrical current. Their goal is about to capture about 50 milliwatts of power for "ambient charging" -- which would at least be enough to top off the battery while the phone is off. Unfortunately, right now their current prototypes are only pulling down 3 to 5 milliwatts, and many in the industry are convinced it can't be done (don't worry, Nokia, that's just The Man, keeping you down). To be honest, we're not totally sure were comfortable with the thought that there's enough RF floating around to make this even theoretically possible, but as we slowly come to grips with our own mortality, we imagine we'd gladly pay an extra $70 or so for the privilege of never having to charge our phone again. Nokia itself isn't over promising: they plan on supplementing this juice with solar power, and thinks it'll be three or four years until it makes its way into a handset -- probably around the time your existing iPhone contract dries up.
