Simplest oscillators for DC

(if you cannot obtain a p channel JFET, it can be replaced with a pnp transistor plus 2 resistors):

Very interesting, especially the "regenerative receiver", and I would like to test it, because it is a way to easily implement the principle mentioned in this NASA patent, more easily than by the method described therein, because we could use only one coil instead of two.

The radio signal received by a coil on a ferrite rod is amplified, and positive feedback feeds another coil on the same ferrite.
This increases the efficiency but this patent made me understand something else much more fundamental.

When a current flows through the receiving coil, it causes a magnetic field that opposes the ambient field of the electromagnetic wave. As the energy is conserved, the cancellation of the energy of the ambient field causes it to be relocated even further into the ferrite. This is why the resonance by an LC circuit, which increases the current in the coil, improves reception.

When received energy is amplified and injected back into the ferrite in phase, larger areas of the ambient field are attenuated and more energy is recovered in the ferrite (with the risk of self-oscillation). Since this re-injection can provide as much or even more current than a tuned LC circuit, no tuning is required and broadband antennas with as much gain or more than the tuned equivalent can be obtained.

This is used in so-called "non-Foster" antenna matching circuits, which use for example negative capacitances or inductances,  example here.
The interest is remarkable, because the antenna behaves as if it had much larger dimensions than its actual physical dimensions, which makes it possible, in addition to improving the gain, to improve the noise factor, which is impossible without this technique, whatever the antenna amplifier we would use.

I don't know if this brilliant idea for radio reception of small signals can be useful for energy.

thx dude! Invented cold fusion last night, so need to read those articles later

...Invented cold fusion last night...

You'll have to tell us more about it.

You'll have to tell us more about it. 

Well I might have to give it a year or two more

If you setup your research framework like I have, then you need to start turning things upside down. What I have seen they are trying to control plasma with magnetic fields and this way get to the temperature that is needed for their elements to combine and then release extra ions or electrons.

I found something that is self contained. Like I have said before I will publish anything I find out open source. I see no point in talking about my discoveries here, before they are validated or scrapped.

Digging into Maxwell now and trying to figure out who was wrong and was something an error or somebody was hiding something. Maxwell even simplified his theories after they were criticized and after that they were raped by Heaviside, Lorentz & gang.

PS. I do not agree with you, that we have well established rules & physics and we should not look into it, because it works so well as it is. I'm paraphrasing, but the jist was like that. I base my research on the hypothesis, that if free energy exists, then there is active suppression. So if anything "real" is done in universities, it is done under NDA and national security. Other "real" research is done in military labs. What we get in schools is diluted or plain false. What you get from these schools is a religion and you will defend this religion to the end, because otherwise it would mean that all your hard work was for nothing, your thesis was based on a lie and that framed "crusifix" on the wall is only a reminder how gullible you were. So you push on as a "priest".

But this is my research and you need to take the red pill to agree with me. So if this all sounds to you like its crazy talk, then just move along.

PPS. I understand I have made people feel bad with what I have said (about a lot of things) and I am sorry for that. In the future I try to STFU

PPPS: I will attach BARRET's take on Maxwell

Conspiracy theory based on none fact.
There are thousands of researchers around the world, in countries with different interests. If something abnormal could be seen by a military lab, other researchers would also see it, who are not subject to secrecy, and anyway on the number of people aware, it would be impossible to prevent leaks.

About Maxwell, Faraday and other pioneers of electromagnetism, everything was based on reasoning in a 3D space. So there are subtle differences sometimes depending on whether we use the equations of one or the other, because electromagnetic phenomena are relativistic, you need 4D otherwise you only have approximations.
Relativity is the ultimate answer if you want to calculate magnetic fields, currents... (but it's more complicated) because it all comes down to the "point of view" of the charges moving relative to each other, which modifies the topology of the Coulomb field. The magnetic field is the Coulomb electric field modified due to velocities. With relativity, everything can be treated with electric fields, and inconsistencies between 19th century equations, or paradoxes, are eliminated.

I understand that Barett disputes the completeness of Maxwell's equations in the paper you provided, I even agree that the Aharonov-Bohm effect can be explained outside quantum mechanics, but to mix QM and classical physics, without going through relativity, I think he uses a wrong method and that he will fall into other errors of the same type as those he hopes to correct.
