  1. Is this for real..??

    Depends what you mean by "for real"?

    If you're asking whether it's possible to extract energy from an
    antenna, the answer is yes. Crystal radios have always worked this way.

    http://en.wikipedia.org/wiki/Crystal_radio

    Note the historical lack of any government attempts to keep that
    technology quiet.

    Indeed, energy always has to come from an antenna, or there'd be no
    signal for the receiver to receive.

    If you're asking whether it can be used to have a measurable impact on
    your electricity bill, the answer is no. The amount of energy that can
    be extracted from an antenna is miniscule, which is one reason no one
    uses a crytal radio for their listening pleasure these days.

    I have heard of something similar where you have a giant (or large) fence
    made of chook wire and an anode at the top & and a cathode bottom of one
    end. Works best in a windy area, evidently the wind passing over the wire
    causes electrons to flow and it is possible to charge a battery with it. The
    obvious problems are
    1. no wind
    2. thunderstorms.
    To prevent backflow a sparkplug was used as well the spark did the charging.
    I did not pursue this line as I did not want to burn the place down. HTH
     
  4. In the video a small generator can charge a mobile phone.

  5. So it's not possible to build a generator large enough to have any
    practical use, because of the limited capacity of an antenna to power
    it? What about using a bigger antenna?

    It shows a wire being plugged into a mobile phone. No evidence that that
    wire was connected to the device. People have been known to lie to
    obtain money.

    Still not. Ultimately, it's limited by the power density in the region
    of the antenna, which is simply not that great. The site is a scam, pure
    and simple.

  8. Not unless you are talking miniscule (nanoamp order) "energy
    harvesting" systems.
    This might help explain why:

  9. Of course there is free electricity (unless old Sol starts billing us) it
    is called solar power.

    Back when I was in Uni we used to have free electricity, courtesy of a much
    modified electricity meter. Rare Earth magnets are amazing things - when
    properly placed.

    Such things exist but the physics makes the situation such that unless
    you have incredibly high energy levels around the genny you get out less
    than goes in , it might be viable on the suns surface assuming you survive
    Years ago in Luxenburg I saw a string of light glowing well while
    unplugged iluminating a cafe' but thats because the local 100kw radio tx
    was about 100 metres away

    That does not follow considering the operation of a light dependant resister.



    Plenty of people listen to crystal radios, we built ones with a single component
    plus earpiece, had old military high impedance headphones, amplifiers...


    Jaycar or Leisuretronics had a solar powered hydrogen generator kit. I wondered
    if it would scale up for practical fueling purposes, apparently it does.

  15. **No, it cannot.
     
  16. **It's not about size. It's about location. The size of the antenna relates
    to the frequency of operation. Your TV enatenna, for example, sucks a minute
    amount of energy from the TV transmitters. Think in terms of pico Watts
    (10^ -9 Watts). And a TV antenna is not a small device. Location, OTOH, is
    vital. It you (could) run an antenna a few hundred kms straight up and
    anchor it (somehow) in orbit, you could extract significant amounts of power
    by virtue of the antenna 'cutting' the magnetic lines that surround our
    planet. Scientists are working on just that. It is WAY beyond the home
    constructor. Even the guys at NASA can't yet develop the technology
    required. The hurdles are significant.

    People build them out of interest. I did, many years ago. I strongly
    doubt that anyont uses them as a practical way of listening to radio
    broadcasts.
    "which would lower CO2 emissions by using less expensive off-peak
    electrical power."

    It only lowers CO2 emissions if that off-peak power comes from nuclear
    power plants. Otherwise it will usually come from coal.

    "During daytime peak power times, the Solar Hydrogen Station can export
    renewable electricity to the grid, providing a cost benefit to the
    customer, while remaining energy neutral."

    Now, while possibly true, that's just plain dishonest. Energy neutrality
    is one thing. Carbon neutrality is another. If you're using colar fire
    generation at night, and then displacing gas fired generation
    (typically) using solar power during the day, then you may be energy
    neutral, but there will still be a significant net CO2 production,
    because coal fired generation produces more CO2 per unit energy output
    than does gas fired generation.

    You seem to have focused on the hybrid power induction phase and missed
    the beauty of a few thousand dollar solar panel adding 1/2 kg of hydrogen
    to your tank for a free daily 50km trip.

  19. If you get solar installed (panels and a inverter), and you have an old
    analog meter- the one with the dial spinning in the center- you can be
    connected immediately, but if you have a digital meter you must get a
    'smart' meter installed b4 they'll turn it on, and that can take a month
    or two.
