    'It's a really exciting way of taking power from other sources than what we would normally think of.'

    Prof. Allen is obviously not a Professor of English, or he has Ernie Wise to write his speeches.:Rofl1:

    His idea could work well for watches, and perhaps mobile phones.

    An interesting one, why ? Because just up the road a farmer was successfully prosecuted for stealing electricity from the BBC. He was near the Droitwich transmitter and laid out a long aerial which gathered enough energy to light his pig sheds.

    Although this bunch have decided to try and patent it, rf energy fields have been used for years to power some things. The military have all sorts of equipment that utilises it. There is no way it can be used to power vehicles or start them though, as without a large enough collection device, the power available is very low

    Its interesting though as most people dont realise the possibilities, unlike the farmer mentioned above caught harvesting energy from the BBC's transmitter

    I know you are 'South of Manchester' Brian, and obviously further south than the farmer (as he's just 'up' the road) - but the Droitwich transmitter is one helluva long way south of Manchester!

    :Rofl1:

    HOW long was the cable ????? :Eeek:

    I can't see how this could work even for mobile phones. The amount of RF energy transmitted and the power used by the processor in a phone would far exceed what could be harvested via RF.

    It may work with a monstrously sized arial. But you couldn't fit that in your pocket:Rofl1:

    And for watches, why bother when mechanical action chargers work so well.

    I think this is pie in the sky myself. We already have inductive charging which is about as good as it will get without batteries or cables.....

    I can't think of any common device that could make use of this?

    I think this sort of technology is aimed at powering small devices in the home - it wouldn't be any good for devices that use quite a lot of power for extended periods like a mobile phone, or were used away from sources of RF (i.e. away from the home)

    I'm surprised they managed to prosecute unless it was on the grounds he didn't have a TV license for what could be deemed television receiving equipment (even though it doesn't display a picture). The exception might be if he built a huge antenna in the air near the transmitter which was in effect creating an RF shadow and reducing the signal strength for consumers in the lee of it. If not then to prosecute him for using the RF power that would otherwise have just been absorbed and lost in his buildings / land seems like me suing my neighbours because my lawn sprinkler oversprayed onto their lawn and they therefore "stole" that overspray to water their lawn.

    Who remembers crystal radio sets (this gives away my age):RollEyes: I'm sure they worked on the same principle with the power coming from a really long aerial to work. I made one when I was about ten years old and surprisingly for me it actually worked:thumb: picking up the "home service" a treat, but it did need about 50 feet of wire aerial to function. :BigGrin:

    Small (off-topic) point...

    You don't need a TV licence just because you own equipment capable of receiving TV...

    Regards
