Finally, putting Tesla's inventions into mainstream.
Nokia powering up self-charging cell phone
No more telling Mom you can't talk because your cell phone is "about to die"--it soon could be charging itself as you speak.
The Nokia Research Centre in Cambridge, England, is working on a prototype system that would eliminate the traditional cell phone charger.
The system collects energy from ambient radio waves emitted by antennas, TV masts, Wi-Fi transmitters, and the like. This might all sound uber-scientific, but we've been using this technology for years. Have you ever exited a store, only to hear the beep, beep, beep of an accusing alarm system? Many retailers use radio frequency identification to prevent theft and track inventory. Like RFID tags, the Nokia phones would catch radio waves across a range of frequencies, harnessing them for power.
Nokia's goal is to get cell phones to harvest about 50 milliwatts of power. Currently the prototypes are able to harvest up to 5 milliwatts, but at least 20 milliwatts is needed to keep phones running in standby mode indefinitely without the need for a recharge, the U.K.'s Guardian reports in an article on Nokia's research.
We're not quite sure what features 50 milliwatts could power: music playing? 3G Internet browsing? As consumers increase their business- and entertainment-related dependency on cell phones, Nokia might have to adjust its 50-milliwatt goal. For a more functional lifestyle device, the phone would need to be paired with a solar-paneled case, or even an occasional wired charge.
The Nokia Research Centre has said the technology will take three to five years to develop. Though this would presumably be the first time electromagnetic radiation is applied to a mainstream consumer product, wireless charging has already hit the market. This month, Palm introduced a wireless charger, the Touchstone, for its much-anticipated Palm Pre.
The Touchstone uses a method referred to as inductive charging. The electric toothbrush is one of the most common devices that applies this technology.

That's not Tesla Tech. That's collecting stray EM radiation from other man made signals. This is a common accusation and misconception held by those that have no understanding of radiant energy as related to conventional electro-magnetic theory. There were none of those things around in Tesla's time for him to collect stray radiation from. Duh. Even if there were, the amount of power available is small.
Tesla's work was to harvest energy directly from the fabric of space-time (vacuum) by collecting the greater environmental reaction to a transient pulse that he supplied. Current electronics products cannot directly use radiant energy even if those devices were to be changed to collect the energy. A capacitor or battery must be used to store and convert it to conventional current electricity.
I am getting so tired of Tesla's name being slung around as a catch word for sales on products that really only barely brush the surface of what Tesla's work really was. I guess the more shit products that bear his name, the harder it is to find his work instead of work in his name only.

Oh, thats right. But I was excited there atleast getting somewhere. It beats burning fuel.
