Copper Shield Or Neomagnet To Block Or Turn EMF Into Constructive Use

02/06/2014 12:17 AM

Dear all:

Thanks very much for the useful feedback.

The next question must then be:

Should I use copper to shield off emf? Or should I use a huge neo magnet to turn the emf into constructive use.

Thanks in advance again.

Whichever costs less.

...Or, on the theory that you get what you pay for, whichever costs more.

I am getting greedy.How about harnessing the emf from the power station to generate free energy?!!

This is possible, but I think illegal.

Illegal? Really? Can you cite the law or laws that make it so?

I ask because a fair amount of work is being done, or has been done, at least in the US, to capture and use the "flea power" that is available if one can rectify the RF energy that is radiated by every TV, Radio, Automobile Ignition system, etc. In AM radios, a diode is used as a "detector" circuit to strip out the "intelligence" (the modulation imposed on the carrier) before the resulting signal is fed to the tone controls and final amps to produce an audio output. The resulting energy left over from the now rectified carrier signal is usually tossed, but when I was in the navy, we found some creative uses for it. Not a lot, because LEDs hadn't been invented yet, and there just weren't a lot of low power devices around (my "portable" AM radios used multiple cold-cathode vacuum tubes to do their work, in place of the discrete transistors and components that followed, to be further followed by single purpose IC chips, followed by LSI chips, followed by VLSI chips, followed by ... well, ultimately, today's SMD chips that do everything we needed an entire chassis to accomplish, but in one little tiny chip I can barely see!), but we did play around with the "free" energy that we trapped.

So, how can it be illegal, in today's age of LED's and Joule-thief circuits which could easily used the "detected" power of "stray RF" to charge a cap, light an LED, and maybe, even power a "stutter bug" robot? A stupid, simple robot, maybe, but still one that, purpose built, could do work.

I've seen that statement many times, and never thought to ask for clarity, but can anyone in the US (cause that's where I live, and under US law is where I have to play) point me to the appropriate section of US law, either Federal, or, if you know VA law, local?

Inquiring minds want to know. And I want to keep my science students out of the clink. And some are working on, or have worked on, that application.

Why let greed stop there (rhetorical question - NNTR)? The harnessing of free energy from nearby radio transmitters by installing tuned antenna circuits is also illegal.

However, shielding using an aluminium foil hat is not illegal and is routinely practised by various subscribers to this forum. No doubt photographs will follow...

Interesting question arises, if a person constructs shielding to protect themselves from "emenations" of a substation or other facility, and those shielding cause power losses from the facility, is this then also illegal ? The person is not using the drained power for their benefit, beyond preventing detrimental effects of the "emanations" ( self protection ).

I do not subscribe to either camp; I am wondering about the liabilities of taking actions like these.

No.

Firstly this is almost certainly illegal.

Secondly, losses can be tracked down the line back to your location (so you would get caught if you were able to get usable quantities of free energy).

Thirdly, the amount of free energy you can get, even with a giant coil of wire right next to the overhead conductors is laughable (the TV show Mythbusters tried this and debunked it). Think lighting a torch, not powering a house.

If you are SO concerned about moving house next to power lines, why not move somewhere else? Shielding a residence properly is NOT going to be cheap.

How about finding something better to worry about like perhaps leaving a legacy of having helped others throughout the remainder of your life rather than becoming the guy known for being so afraid of dying he never lived his life.

Forget trying to harness energy from radio waves, the big money will be made fracturing water to reclaim the hydrogen part of the H2O for fuel. I plan on running my car with only water. Now, what to do with all that left over oxygen?

Got the humor, Cap, but I'm not trying to salvage large amounts of energy, and it ain't over-unity. Some poor jerks are pumping out giga-watts of talk power to saturate the environment with talk that few want to hear, or pretty pictures most only occasionally want to see, and most of which will not be collected by any INTENDED recipient even when the associated collections devices are turned on, because the signal is non-directional in nature, and splatters all over the landscape. Collecting and using it makes just as much sense as harnessing the motions of the human body to power devices implanted in it, via piezo-electric devices. And THAT, my friend, is serious science and medical work being done in labs all over the US, and in at least a couple of places in Europe and the UK.

And all of is is flea-power. And all of it is no more than collecting available, and currently wasted energy, and converting it to a usable form, to power devices, many of which are being designed specifically to need no more than the miniscule amounts of energy available by such methods.

IT AIN'T OVER UNITY, AND IT IS GOOD SCIENCE AND GOOD TECHNOLOGICAL APPLICATION!

I know yelling something won't convince the sceptics, but it makes ME feel better, anyway!

Chicken fence and shielding paint will do fine over 30 dB shielding.Just chicken fence will do round 25 dB or so I suppose. See a sample below. Shield your sleeping areas. Rest is not that critical. About turning it into energy, check diminishing returns from economy class. And as a principle keep away from "free of charge" and "unlimited" labeled things without even looking back.

Sounds like what you really want is to develop a printed thin film tunable rectenna set to 50/60 Hz and piped onto an outer layer ballistic conductor via a AC/DC nano converter. However, I'm not sure how someone would be able to receive the 5,000 to 6,000 meter wavelength within reasonable dimensions.
