    "Free energy from the air. It sounds like a fantasy but that is what the entrepreneur and former science minister Lord Drayson has just unveiled at London's Royal Institution.

    The technology involves harvesting radio frequency energy from existing wireless and broadcast networks, from 4G to digital television. Lord Drayson says it's a world first: "It doesn't require any extra infrastructure, it doesn't require us to transmit any extra energy, it's recycling the energy which isn't being used at the moment.""

    With a bit of luck, we'll be able to suck up all the juice destined for mobile phones and walk down the street without fear of being bumped into again.

    What "free" energy?
    The energy used in the demonstrations was generated for a purpose and to hijack it for other purposes is simply wrong

    I was told, some time ago, about someone close to a Radar installation being found with a loop of wire round their house to generat electricity. I think they were prosecuted.
    Surely all that harvesting would require stronger signals and so more generating energy to make up for what was being absorbed?

    Yes, however I think it would be impossible to detect and prosecute everyone who who took advantage of it. If you remember back to the days of illegal CB radio, there was never a ban on owning the equipment for it. Only a ban on transmitting from it. The law was impossible to police, so the law was changed to allow CB radio on a specific frequency.

    If they increase the energy, it will merely allow more powerful devices to be used.

    Before we get too excited, Radio amateurs communicate around the world transmitting less power than an average lamp bulb.
    The total power output from a large TV transmitter is ~1MW, which is enough to power only 1000, one bar electric fires. How are the remaining 5.999 million homes served by the transmitter going to keep warm? They won't even have TV to watch. It's the same with wind power - uses up all the wind. No-one ever thinks of that.
    Oh, and your house is colder if you are absorbing all the energy falling on it with solar panels.

    Does that mean my dog will get blamed less? I hope so. You wouldn't want to see his face with his ears plucked back in a sad fashion and watch him wander off with his tail between his legs when he hears someone ask "Did you do that?"

    Bring on more wind power, I say. Nobody other than sailors goes much on wind. A cooling breeze on a hot day is nice, but who wants wind on a bitterly cold day? If wind turbines use it all up, it's only for the betterment of all.

    Can't all those gyms that have treadmills be hooked up to some sort of kinetic generator contraption?

    If you carry a fluorescent tube near power lines, it will light up....
