Wireless Charging Start-Up Claims 30-Foot Radius

Lucas123 writes "At Disrupt this week, Ossia Inc. demonstrated for the first time its wireless charging technology that founder Hatem Zeine said has a 30-foot radius and, like WiFi, can charge through walls and 'around corners.' The technology, still in prototype phase, uses the same spectrum as other wireless standards, such as WiFi and Bluetooth. The Cota wireless charging system includes a charger and a receiver — either a dongle device or chip-tech integrated into a product, such as a smartphone or battery. While it has yet to be miniaturized, Zeine said the wireless technology will eventually be small enough to fit into a AAA battery or any portable electronic device. While the technology has wider industrial implications, as a consumer product, a charging unit will likely sell for around $100, he said."

  1. Potential Snake Oil by The+RoboNerd · · Score: 5, Informative

    He attached a cube to an iphone, held it in the air, and it started charging. We have to go by faith that there are no batteries in the cube. Sorry but this sounds like snake oil.

    I think this is the best idea I've seen since I invented it almost 100 years ago!

  3. Re:The "2.4 GHz resonance frequency" thing is a my by erice · · Score: 3, Informative

    It may not be technically the resonant frequency of water, but there is something special about it:

    The 2.45 GHz is a kind of useful average frequency. If the frequency was much higher then the waves would penetrate less well, lower frequencies would penetrate better but are absorbed only weakly and so once again the food would not absorb enough energy to cook well.

    My understanding is that the 2.4Ghz band was assigned for unlicensed use because it was already cluttered with things like microwave ovens and was, therefore, undesirable for licensed use.

    What kind of super-ionization will it do to our body cells ?

    None, because photons with energy on the order of 1-10 ueV don't ionize anything.
