A New Wireless Power Transmission Sheet

Roland Piquepaille writes "Several companies have started to sell power 'pads' that can charge your cellphone when you put it on the pad's surface. But these silicon-based pads are expensive — and relatively 'specialized.' Now, Japanese researchers have built a plastic sheet which could power all the devices placed close to it. So far, this 4-layer sheet, which uses printed organic transistors and plastic MEMS switches, can deliver up to 40 watts of power — enough for some laptops. The technology is apparently efficient and inexpensive to produce. But as the devices to recharge will need to incorporate a special receiver, don't expect to see these plastic power sheets on sale before several years."

    Sure it's cool to charge your gadgets with a little plastic pad, but I contend it's more fun with a Tesla coil

    I'm all for Sony implementing this.

    Think about it -- when the charging device explodes, there's a chance that your laptop will be blown clear and suffer no harm.

    What is Bluetooth used for? To eliminate wires? Are you serious?

    what did you think it was for? eliminating macramé tea cozies?
