Power Harvesting: Induction Magic

Figuring out how to harness electricity from power lines isn't the only amazing goal that Air Force research lab engineers achieved. They still had a question: Could electronics such as cameras and radio transmitters be fired up by placing them on power lines?
That process -- capturing magnetic energy and turning it back into electricity -- is called electromagnetic induction. The answer was "yes," and now that the engineers can harness this energy, they have big plans to power other devices.
Using induction is "taking advantage of all the power lines that are available all over the world," says electrical engineer David McDaniel. "It's like when you were a kid you're working on your bike -- it's like that, times a thousand," says electrical engineer Pat Marshall. "I love it! I love being an engineer -- electrical, of course."

Neat stuff coming into interest lately thankfully

[@PafiTheOne]

This type of energy collection method requires a very short, high cross section of closed iron core (with almost no air gap allowed!) surrounding only 1 of the power lines. Basically it is a current transformer with a secondary load that is used to power some sensor, camera, battery, etc... The primary current is variable, determined by the load of the power line, typically I=100...1000 A. If the device needs for example P=10 W, then induced voltage/turn must be Vt=P/I=0.1...0.01 V. For 0.1 V you need an iron core cross-section of A=Vt/(4.4*Bmax*f)= 0.1/(4.4*1.4Tesla*50Hz)=3.2 cm^2. From the fact they used even bigger cross-section I assume they aimed for even lower primary current, or higher consumption, or couldn't manage to keep the air-gap tight enough. To keep the device safe from overloading a smartly controlled DC/DC (fly-back or boost type) converter is needed on the secondary (after rectification).

[@aquamastertheonlyone]

If it's through magnetic induction it's not "energy stealing". My uncle has a little farm where there is a high voltage transmission line passing through. When you go near it, you feel the static electricity, you hear the energy "hhhuuuummm" and from time to time there are electrical discharge (like lightining). I think it's 14000v line (come from ITAIPU). In Foz do Iguaçu city, in some area of the city people can light a light bulb just putting the light bulb on the ground, the energy comes either from ITAIPÚ generators or from a transmission line from ITAIPÚ. It's not "stealing" if it is "leaking". They uses wires without insulation, because "it costs too much to insulate these types of wires" 👍

Is it stealing power needed to keep the power flowing to people, or is it gleaning power that’s already lost and useless to the functioning of the power grid?

[@cyganmarek]

power is harvested from ether directly by power lines and it's free energy, so no power plants is needed as there is no need to burn anything to harvest the power

[@kynonikos]

It is stealing because the device's magnetic field will interfere with the line's current and it will create voltage-current phase shift (φ). This will cause a percentage of active power (P=V*I*cosφ) to become reactive (Q=V*I*sinφ), keeping apparent power (S=sqrt(P^2+Q^2)) constant. After all energy cannot be created out of nothing, can only be transferred or change form. The device takes energy, the line loses energy.

Electrostatically Harvesting Power from High Voltage Power Lines. Note from author: Please do not try this experiment without a thorough knowledge of electricity! Please understand that it is illegal to take power from power lines. This is an experiment only. If you run a single wire along a high voltage power line, (= or> 340KVAC), you will harvest a fair amount of voltage at micro amp levels. WARNING: KEEP AT LEAST 30 FEET FROM THE HIGH VOLTAGE LINE!! DO NOT DO THIS EXPERIMENT ON WINDY DAYS!! The longer the parallel wire, the higher the voltage and amperage you can collect. Run your (antenna wire) parallel to the power line in the trees adjacent to one outer phase of the power line. The higher the wire, (antenna), the better. Use small gauge bare wire hung from fishing line for insulation and support. Run at least 200 feet of bare antenna wire. 400 feet equals twice the power collected. Use a fishing pole and weight to put up the wires in the closest branches of the trees next to the HV line. WARNING, DO NOT TOUCH THE ANTENNA WIRE! YOU WILL GET SHOCKED! I recommend two pairs of rubber gloves and good boots for this. Ground the Antenna wire while you work until the transformer (s) are installed and you are ready for power. Provide a single or several 5 foot copper-plated ground rods at your termination point for the transformer high voltage return to ground. More grounds are better. The ground completes the high voltage antenna circuit. The trick is to present a minimum load to the antenna wire and to step down the electrostatically induced voltage. We need a very high voltage transformer to do this. A ham radio plate transformer rated at 10,000 volts works good. Neon sign transformers work well. You can use several used oil burner transformers with the secondary in series. They are 10 KV each so you can make a 50 KV secondary with five of them. Much better! Remember, the higher the transformer ratio from the high side to the low side of the transformer the better match you will have to the source (the power line antenna). We then connect the high voltage transformer secondary (HV) winding to the antenna and the ground. Separate transformers MUST have the 120 volt leads in parallel and IN-PHASE. You have created a capacitive-coupled step-down transformer. Place a 4 watt, 120 volt light across the 120 volt terminals of the transformer. If the light pops and you measure a higher voltage, you may add another single transformer to get to the voltage you desire from the HV transformer (s). You need to measure the AC voltage out of the HV transformer primary and find a 120 volt transformer for that voltage. Example: 600 volts out requires a 600 volt secondary and a 120 volt primary. Place this step-down transformer after the HV transformer. You may also ground the far end of the antenna wire to create electromagnetic coupling to the power line. No other circuit changes are required for this. Bring along some different wattage/voltage lamps, a car battery charger and small battery and some small AC motors to see the power you have collected. Have fun! Author: I am purposely not saying I ever did this. Work safely and remove the antenna when done so it will not blow into the high voltage power line.

So we can put them on our power lines to power our house and not pay Edison because were making our own power? What is the ratio of power you get off a line 120 volt line = ? Volts with # turns x gauge of wire makes 15 volts! Is there a formula?

[@PafiTheOne]

No, you can not. This is not the aim of this development, and it is not capable either. This is a current transformer, while your house needs a voltage transformer. This transformer can only supply small, and strongly ground-isolated loads, while your house is a big and ground-connected load. The owner of this device probably pay for the power company, but the price of the electricity for its whole lifespan is much lower than the price of this device. The whole electricity-bill topic is quite irrelevant. The point here is that small devices can be placed along the power lines instantly without having to build regular, giantic and expensive voltage transformers.

We have that, it's called trains. More seriously, this is a match because the line carries insane amounts of currents.

dolphin2303 not stealing? just because no meter is currently measuring does not mean there is no energy transferring from the wire......its the only way the device gets its energy...by taking it from the wire via induction. if energy could magically appear in the device with none being lost in the wire, then e equals mc squared is totally wrong and we can all get free energy. we can cut the production of electricity down because we can just duplicateore with more devices. you are deceiving yourself if you don't see this as theft. be careful with your project.

@@mrchordstriker It is not stealing, because it obviously requires the approval of the power distribution company, or even the user IS the power distribution company.

@@PafiTheOne believe it or not, sucking some energy from the lines, DOES mean the end user might just get a brown out (shortage of electricity), on their end. Because someone took some energy enroute to their home. They paid for that electricity, and the company fell short and failed them. Like a boss, the hydro co has to take responsibility for the shortcoming. What do they do? Find out why and where their failure was. Guess what they find someone sucked their energy out of their lines like a mosquito. You are arguing mosquitos do not steal your blood. Its the same. Enough mosquito's and you will react. Same legally with hydro being sucked out of power lines. You may think your extraction does not have consequences because it is seemingly slight and inconsequential, until there are ten million with your point if view. Some counties already experience county wide brown outs from electricity demands, a pile of mosquitos will make it worse. You may argue it is not stealing until the legal world steps in. Ok. But it IS taking frim someone who supplied the power in the first place, and taking a tiny amount ends up with someone who paid for that hydro, doing without that hydro. You may be a tricky word gaming democrat desperate to excuse stealing or else a dumhead it doesn't really matter. Hydro companies will push the legal end of taking other peoples property if that's what it takes. To play word games beforehand, is usually what prompts legal acts.

@@mrchordstriker You have understood nothing. The purpose of this development is not stealing, what is more, it is *impossible* to use for stealing electricity, because such device costs much more than the price of the energy can be harvested during its whole lifespan. It is not intended and will never be used by people who want to tap into power line illegally. This idea tells more about you. The whole topic of stealing is an ignorant, irrelevant idea, this is why I mentioned the terminology refers to a non-technical domain and should be abandoned. The typical expected users of this technology is the owner of the power line, police or other security authorities, FBI, etc... Do you really think if they use this technology, then they steal energy? (Weather they pay for the electricity separately or not.) The weight of these devices, or the potential failure of them poses much more risk then the electric load they cause, therefore they will be strictly regulated before mass production.

PafiTheOne What a long statement wow. I went to college to learn electromagnetism. Graduated top of my class. To charge up anything using hydro lines, is to take from the electrons in the wire, into your transformer in your device, into your batteries. If you do not want to call it stealing because it gives you the iggies, well then call it taking. You are taking electrons from one place, and putting them in your batteries. Period. That is my whole point. Please do not badger me about stealing, I only know the physics, not the legality of it. That part is up to you. Have a day.

Every metre in altitude there’s 100v of electricity. Since it’s inception from the early 1930’s electricity has been literally taken freely directly from the atmosphere and you’ve all been charged. There’s not a single proof of video real hard evidence that electricity is produced in coal powered electricity stations. They only produce carbon based products. Show me a turbine in a coal power station actually providing power into the grid and the process and quantities fed into it. Compare the power output of the earth to what the national grid produces.
