Wireless Power Recharging Nears Fruition

Posted by timothy on from the lead-codpiece-is-all-that-prevents-it-now dept.

AlexanderT writes "Mobileread.com is reporting that wireless power recharging of mobile devices may become commercially available by the end of this year. Various recently filed patents by Cambridge UK-based Splashpower Ltd. indicate how close the company is in realizing this technology."

  1. Electric Toothbrushes by n0dalus · · Score: 3, Insightful

    I've had my electric toothbrush that charges without contact for years. It's not very special. It's just a magnetic field that works like the two parts of a transformer.

    I'm trying to figure out which person you're referring to, the documentary bit seems to point at tesla, but the other part points at edison...
    The sort of fake documentary I mean is the ones that talk about the boat ramps on Easter Island as proof that they are roads leading to a sunken continent. There's been stuff like that done about Tesla, using him as an excuse to push their warped ideas.

    Edison was a very capable and not entirely scrupulous businessman, and he wasn't going to let the fact he had a system that was far less safe or efficient than Teslas - so he called Telsla a crank and a dreamer that was promising the impossible. Some of the mud stuck, since Edison was more or less a national hero, and Telsa was from some bit of Eastern Europe full of untrustworthy Jews and Slavs (nineteenth century USA attidudes folks), and since no-one would go against Edison initially Telsa would tell anyone that would listen that there was a conspiricy against him - which was effectively true, but made him look more like a crank.

    In the end it was Edisons system that we use at low voltages (transmitting DC is impractical), and Teslas system to move the current long distances and run motors of any decent size. There's nothing weird or mystical about AC current or even broadcast power (which is just high intensity radio waves).
