Researchers Power a Security Camera With Wi-Fi Signals

Kristine Lofgren writes: Nikola Tesla dreamed of a world full of free, wireless power. While he never accomplished that dream during his lifetime, researchers at the University of Washington are doing their part to make it a reality with a breakthrough in wi-fi powered electronics. Dubbed PoWi-Fi, the team led by Vamsi Talla were able to recharge and maintain consistent low-level power over a number of different devices at distances of up to 28 feet.

Cameras actually used to work like that! Of course, they used chemicals instead of electricity and each 'sensor' only worked for one image...
