    Firstly let me say i don't know the first thing about electronics...
    Thus the question..!!!

    What i would like to know is, is it possible to use a normal power
    supply ie plug in the wall!! with just having a plug in the wall
    without the lead.... IE im trying to consider ways of transferring the
    power from a plug in the wall to a device without the use of leads..

    Before you all start screaming about chargers, this has been considered
    however the product will only work for minutes on a charge. and i am
    looking for something with a longer (if not indeffinate) power supply
    from the mains without the use or inconvenience of leads..

    Is this at all possible if so can you direct me in the right direction
    either a supplier of such products or the general idea how it can be

    Many thanks for you time, and forgiveness for my niaivety

  2. Google for "Tesla".

    If your device will drain batteries that quickly, then you are using
    quite a lot of power. Powering a device remotely using electromagnetic
    radiation is possible, but only for very small devices, like rfid chips
    or crystal sets.

    Tesla supposedly powered a car remotely. However, his hair was probably
    standing on end when he did it... ;)

    Laptops are generally used away from the mains, and consume lots of
    power. A lithium laptop or camcorder battery might be what you are
    looking for.

  3. An electromagnetic feild can be used but the device would have to be in
    close contact with the plug. like electric tooth brushes do, no plug
    connectors or wires, but no good if your device is not going to be ontop of
    the power supply. Sorry can see it being done anyother way.

    power supply...
