Why does an amp make a 60hz sound when I touch the input cable?

The room is for a MRI, it is a little different in construction (the room is made of wood also it is separated by doors) as half is a MRI suit and half is a surgery. This allows the surgeon to get an up to the minute picture of the patient. When not needed together both rooms operate independently. Copper is used as it is a better shielding material than aluminum, also it is not possible to solder the seams of sheet aluminum.

Push an electron into one end of a wire, and one pops out of the other end almost instantly. The delay is as would be expected from the speed of light. The catch is that it's not the same electron.

I think it's a pretty well known principle that energy can move much faster than the medium that carries it, is it not?

I think it is a good question. What is the medium that carries radio waves? They can pass through a vacuum or even solid matter like wood. Yet they pass along only on the surface of metallic objects. They bounce off of metal, hence the point of a wave guide in a microwave oven. I wish I had been this interested twenty years ago.

Enzo, so the gas inside produces the light and the coating is energized by ultraviolet light produced by the mercury vapor right? I learned all sorts of stuff today. I had to google it.. But would a neon beer sign glow under the power lines as well? And why don't these farmers use them to light up there fields for free at night hehe... Party in the cornfield... Now if only we could we use a bunch of crystal radios somehow tuned to 60hz instead of the much higher AM frequencies to power our guitar amps in that cornfield under the power lines...

JM, please bring all the redheads in small bikinis that you want to this hypothetical party in the corn field.

Austin, get out your volt meter, and set it to AC volts. Sit the black probe down on the table and leave it alone, or even unplug it from the meter. Now grab the red probe tip with your fingers. How many volts you get? That is your body acting like an antenna for all that 60Hz in your vicinity, and the meter - typically 10 meg input impedance - doesn;t load that down much at all.

The problem with all this free energy is that there needs to be some current behind it if it is to do any useful work. And that is something your piece of wire will not pick up.


The flourescent tube normally runs an arc down the middle, making UV, which excited the phospors in the coating to flouresce. But other things can excite that coating to glow as well. Doesn't have to be UV radiation from within. We had an instructor demonstrating some low power radar gear in a classroom once. A big box (this was the 1950s, so it was all tubes) with a small dish on top facing forwards. Dish about the size of our modern Dish satellite thingies for TV. Of course we souldnlt see the radar beams, but the instructor was ready for that. We turned out the classroom lights, the radar transmitter was already running. He got out a sheet of metal about two feet square and walked out in front of the transmitter dish and held up the metal sheet like a mirror, and he reflected the radar beam up at the flourescent lights on the ceiling. Sure enough, wherever he reflected the beam, the tubes glowed.


In the case of the floursecent tube, we are exciting the coating on the glass to glow, to flouresce. In the case of the neon tube, the gas inside must be excited to its ionization level. That takes more energy than the coating on the flour tube.


Here is another fun experiment. Google "rf probe" and find a zillion hits. One of the first is an image of the "classic" rf probe, which is perfect. It is a diode, a resistor, and a cap, more or less. Preferably a germanium diode. tack one of those circuits together, and connect it to your meter. Now you are "detecting" RF energy in your vicinity. Try spreading out a long piece of wire. Got a speaker cord? Stretch it out on the floor. Now touch your new RF probe to one end of it. Now how many volts you get. Try on AC and DC. But what really is fun - to me - is to connect it to some amplifier, instead of a meter. Try that, and you will be listening to local AM radio stations.


BUt alas, once again, regardless of the volts we may accumulate, as soon as you try to load it with something, it dies. Now stretch a 50 foot wire along parallel to overhead power lines, and you may start to have some energy.

Not sure where my post went, the room is for an MRI, copper is a better shield material than aluminum, also with aluminum you can not solder the sheet edges together.

Post #61, just a few back from here, is still there, I just looked.

[Austin]

This is a video where it looks like he is getting 5 volts or so from the radio waves. But notice the voltage doesn't go down at all when he connects the motor. Is it fake? free energy generator - raw video footage - uncut version - YouTube

[g1]

I don't think it's fake, it's just not capable of doing any useful work. When he hooks the motor to the battery you can HEAR the motor running, and the vanes are moving fast enough to provide some fan effect, or do some kind of work. When he connects it to the coil, there is no sound from the motor and the vanes barely move. I didn't see him measure the battery voltage, so I'm guessing the meter may be on millivolt range, or measuring hum/noise.
Yes there is energy out there avialable for free, but the quantity is too small to do anything useful with. For example, look at solar panels, they are very expensive per watt of energy produced. Yes you can charge a cell phone with one, but you're not going to heat your house with it.

[Austin]

I don't understand how the coil wold make dc without a rectifier unless the magnet is somehow rectifying it. Ansd what is the purpose of the center tap?

[Steve Conner]

Anything with "free energy" in the title is fake. I can't believe we're even discussing it!

Do you consider emitting light "useful"?
Road signs built with super-bright, high-efficiency LEDs are powered by solar panels.

Yes you can charge a cell phone with one, but you're not going to heat your house with it.

Bad example. I have a cousin who has been living in a solar-heated house near Duluth for decades.

[J M Fahey]

The whole *EARTH* is heated by Solar energy, for that matter!!!
And the video is as fake as they come.
1) a *coil* might, if any, "produce" (although I'd properly say "catch") AC voltage; this one clearly shows DC voltage. żżż???
2) 6 volts across a 0.01 ohm copper coil would cause 600 amperes to pass and dissipate 3600W.
That coil would glow white hot in 5 seconds and explode in 10.
That guy should now be using 2 pirate style iron hooks instead of lost hands to scratch his back.
3) the device contains an actual useful element: the cork puller soldered in the middle, to open yet another bottle of good wine.
4) of course, viewer comments already say this and more:

Fake. Battery hidden in the neodymium plate on one side. You can see a discoloration on the back. The antenna going into the air is just a distraction. It really is concealing that the coil wire is cut so the circuit wont short itself out. If nobody can replicate something this simple, its obviously fake.

what is the diameter of the wire? Is length, Its inductance and where did you hide the battery? LOL

And so on and on. Oh well.

Not forgetting that using photovoltaic cells is not an example of "free energy", it comes out of good old Sol.
Try making one work under the sea, inside a cave or at night.
Justy sayin'

[Enzo]

I agree there are batteries in the base plate of the coil - a pair of 3v coin cells. Why would the coil even need a baseplate? COils wouldn't pick up DC voltage anyway - ever see a DC transformer? He waves the coil around, yet the voltage never wavers in the slightest. Apparently whatever free energy field he is tapping into is directionless. Such a small coil would only be efficiant at RF, and his meter wouldn;t read that on DC OR AC scales.

You might also like to try it in "a van down by the RIVER!" with a battery powered amp, you should get no hum.

Unless there happens to be some power lines nearby. Or if the engine was running you would get ignition crackles and alternator whine.

Battery powered amps are nice even when you are in a noisy environment, i.e. you can test low noise stuff without even having to think about ground loops. My latest "Pignose" has two 15s, a BMW battery and a 400W car amp.
