You need to scrounge up a coil of fine wire, 8000 to 10,000 feet. The Navy used lots of equipment that used focusing coils like that in the ‘50s and ‘60s.
The schematic is simple:
If you use a bridge, place the coil across two diagonally opposed vertices, and the battery across the other two, observe correct polarity. The load (bulb, and possibly a resistance, depending on the wattage of the bulb) across the battery.
You need to set it up in a place where it is not messed with, like the inside of a tall etagerie. The axis of the coil should be aligned east-west, and it should be suspended as tall as possible.

You have done this yourself?
Luckily I live up on the side of a hill and my house is almost East-West aligned but I know exactly the direction it is pointed.
I'm assuming you mean a Wheatstone bridge?
Using this diagram, that I got from Wiki, you could simply replaced the R1, R2, R3, Rx, Vg, points A,B,C,D and tha battery to describe how this is supposed to work, where what part goes where or include a link to a schematic you know works.
No, I meant a rectifier bridge, as I previously stated.
Again, you can use the naming of quadrants to specify which diode you're talking about:
Quadrants are I,II, III, IV. And the diodes have a cathode and an anode. So, using a quadrant naming convention, the top right diode is in quadrant I, it has an anode and cathode and the one below it is in quadrant IV and you can point things out by saying, diodes in QI & Q2 joined at the cathodes is where you hook up xxx...
You don't have a link to a schematic, it's got to be somewhere, is this known by some name?
Oh yeah, do the coils need a core?
Thank you, I hope you had a great Thanksgiving!
Except for the capacitor, your diagram is fine. With the battery, the capacitor wouldn’t add any function.
The core would be irrelevent.
The big issue is going to be balancing the load with your coil. We used to have lots of low wattage incandesant available, but they seem to be disappearing. An LED would probably make a good replacement, in which case a smaller coil may also work, but I’ve never tried that. Its probably been 50 years since I had one of these going, but I’ve seen them in people’s offices from time to time. Everyone seems to have a slightly different approach, but they’re all takeoffs on Tesla’s “free power” concept.
A LED should work even better requiring lower power. Unlike much of the above, this is a device I would expect to work. Have fun building it.
You need to hook the coil to the AC input (the wavey symbol) and replace the capacitor with a rechargeable battery and put a LED in the load (the rectangle to the far right). The coil picks up the ambient RF from radio, your wall current, and anything else shaking EM-space and feeds it to the rectifier turning it into DC which charges the battery and feeds the LED. This absolutely should work with enough coil.
OK, now that's different. All it is, is a large crystal radio with a large bandpass so you don't have to tune it.
I was told it ran off the Earth's magnetism and rotation like Tesla's mysterious car power source.
I built one of those in 2nd grade (a crystal radio that is). Since it's using in the above generic schematic, silicone and not germanium diodes, it has to overcome the .6-.7 volt (depletion region) needed to cross a silicone PM junction instead of a .3 volt one of a crystal diode and when you do that, you only pick up the largest signals and I also never tried it with a full wave rectifier but since it's not sound waves you listen to, I guess it's not that big a deal. Hell, I might as well find a cat's whisker if I wanted nostalgia.
I wanted something that could be scaled up, Tesla supposedly powered a car and if it was possible to use the Earth's magnetic field, I have no idea of the upper limit but now you're telling me it's a crystal radio essentially and there is a limit.
Hell, I live around twenty miles away from an antenna farm off of highway 50 in El Dorado hills that I could park next to them and steal power from them, they might not even detect a small amount. I could find power lines that have the conductor's far enough apart so they don't cancel each other out and bury an inductor and steal power that way as well and they would damn well detect that.
I want the schematic to this:
The "energy receiver" (gravitational energy converter) had been built by Tesla himself. The dimensions of the converter housing were approximately 60 x 25 x 15cm. It was installed in front of the dashboard. Among other things, the converter contained 12 vacuum tubes, of which three were of the 70-L-7 type. A heavy antenna approximately 1.8 meters long, came out of the converter. This antenna apparently had the same function as that on the Moray converter (see chapter on Radiant Energy). Furthermore, two thick rods protruded approximately 10cm from the converter housing.
Tesla pushed them in saying "Now we have power." The motor achieved a maximum of 1800rpm. Tesla said it was fairly hot when operating, and therefore a cooling fan was required. For the rest, he said there was enough power in the converter to illuminate an entire house, besides running the car engine. The car was tested for a week, reaching a top speed of 90 miles per hour effortlessly. Its performance data were at least comparable to those of an automobile using gasoline. At a stop sign, a passerby remarked that there were no exhaust gasses coming from the exhaust pipe. Petar answered "We have no motor." The car was kept on a farm, perhaps 20 miles outside of Buffalo, not far from Niagara Falls.
Ok, putting an LED in in place of an incandescant lamp changes too much!
You’re correct, with the big coil it just might operate off of local radio power. But that definitely was not the case with the original. 1000 crystal radios couldn’t light the incandescant lamp.
I don’t know how to get energy out of a static magnetic field, sorry. Doing the thought experiment of having a BA permanent magnet; how do you make a motor without input of energy? I have no clue.
As far as Tesla having a clue about this, I have no opinion. He was a brilliant man who was effectively erased from history which is more than interesting. I am sure there are those here with better information.
Well, I've been thinking of this. Why does the coil have to be oriented East-West? When you used a crystal radio, once you got it tuned in, there wasn't any directional component except to orient it in relationship to the transmitter. Let me think about this. I also have to go into Sacramento to get some wire. I've got a boatload of magnet wire but it's all on metal bobbins which is effectively a core and I'm too old to be winding coils.
If I can buy two or more, 120vac solenoids and cut away the cores, I've got everything else, my only home choices are output transformers and toroid power transformers and those cost me big bucks which I'm not going to destroy for this.
It doesn’t have to be oriented east-west. What you are building is an EM energy scavenger. You are probably going to be getting most of your energy from inductive coupling to your wall power. The inverse square law will not be denied. The more coils over a larger area the better. Bigger coils couple better to longer wavelengths and your primary source is at 60Hz.
>> “Why does the coil have to be oriented East-West?” <<
.
That was taken from a paper by an EE student from Stanford, around 1959, he stated that the power yield was measurably greater if E-W orientation was used. We took him at his word, being mere High School punks working on a class assignment. The crystal radio is working from broadcast power which has various polarities and alignments, not natural magnetism.
I don’t think that using a core should be a problem except with a boxed transformer, just not necessary. None of the surplus radar coils had cores, and they worked.
Did you ever move the coils orientations to see which direction was strongest?
No, I didn’t have access to the data recording instruments that would be needed, but it wasn’t really that important to me at the time. Things were so different back then; stuff that is commonplace now was mostly out of reach to a HS student.
Hey, at least that Szabó guy got patents. That's more than Rossi was able to achieve!
BTW, I love your links. You always seem to come up with interesting background information.

I've really wasted too much time on this, but it's hooked me in like a good mystery book.
2. Any reason to dispute this doctorate? It seems to me that's far more significant than debating an undergrad degree.
I do not believe that Rossi has a doctorate.
Let's look at the text of the letter posted at the Nyteknik site (translated by Google):
This is to certify that the documents before the Secretary that Mr. Andrea Rossi was born in Milan on 03/06/1950, has been awarded by this university, on 10/12/1975, examination degree in Philosophy with a hundred and ten votes of one hundred and ten and obtained the academic qualification of Doctor of Science in Philosophy. This certificate is issued on plain paper at the request of, for the purposes authorized by law.
For one thing, the doctorate awarded by the University of Milan is called a "Dottorati di Ricerca" (Doctorate in Research), not "Dottore Magistrale in Filosofia" (Doctor's Degree in Philosophy) as the letter says. As far as I can tell, "Dottorati di Ricerca" is the name of all doctoral degrees in Italy. I Googled the term "Dottore Magistrale in Filosofia" and found some hits; apparently, that is the name of a MS degree awarded in Philosophy (the actual "I think therefore I am" type of philosophy). But the take-home message here is that the name of the degree in the letter is NOT a degree awarded at U of Milan.
Another discrepency is the time line, which is slightly off. According to the Univ. of Milan website, it is required to have both a Bachelor's and a Master's degree before applying for the Doctorate. The Bachelor's program is 3 years; the Master's adds another 2 years. The doctorate is 3 or 4 years. Assuming Rossi entered school at the age of 6 (the age most Italians begin school), he would have graduated at the age of 19 in spring, 1969. Further assuming that he proceeded directly from high school to college, took no breaks, and graduated each level in the minimum time, the earliest I can figure out someone born in 1950 could have earned a PhD would have been spring of 1977. If he had entered elementary school early, at the age of 5, he could possibly have pulled off a Doctorate in spring, 1976. Either way, his timeline is one or two years short.
Another discrepancy is in the way the degree is described as having been awarded in the letter, with "110 votes". The Italian doctorate is awarded on the basis of several criteria--passing a PhD exam, submission of a dissertation, and a jury examination. As far as I can tell, the jury consists of three members.
Other oddities that stand out are that he supposedly obtained his doctorate on "relativity" and that he has no actual certificate to show for his doctorate. The "relativity" topic is rather nonsensical; in my experience, PhDs are awarded in fields of academic study (for instance, in "Genetics" or "Theoretical Physics") and the topic of the PhD is given in the dissertation title, for example, "Mechanisms of toxicity exhibited following exposure to heterocyclic halogenated hydrocarbons." And where is his actual doctorate certificate? That is not something that people typically lose, and people usually like to display it so that others can see it--my PhD certificate is nicely displayed in a cherry frame, along with my graduation tassels, and I keep it hanging on the wall in my office. Plus, if I should need to document my PhD, I request copies of my transcript be sent; I don't ask for a letter stating the degree I received.
I suspect the letter shown is a fake. The letter shows oddities: the font size changes for no discernable reason, and even though it is not right justified, there are variable gaps between words.
Lastly, Rossi neither acts like a scientist nor speaks the language of science.
I found this information with the help of Google, the U of Milan website, and Google translate.
Me, too--I have no idea why this fascinates me so much, but it does!
