or should we just dismiss it as impossible since we already know everything?
Outside of your comment, I don't think there has been any mentioned over-unity. I've tossed out 88% top 30% using copper. I think if Tesla had an idea of free, it meant free to the masses, not free to generate. In the case of the OP, I think they are just trying to understand more about it. I can certainly understand it seeming a bit amazing but it's certainly not new science.

(this entire post is primarily aimed at Deco56)As Dave said/hinted, it does seem to be related to free energy claims (and other terms, they tend to use).
If you pop over to one of the main chaps websites, and click one or two links (or google search), or however I found the following. It seems to say 'Free energy' and things.
I.e. Eric Dollard, who is both the creator/experimenter, in at least one of the videos, and extensively talked about (in both I believe). His website, leads to the following link (forgotten if directly on his website, or via google search).
Anyway/also, Eric Dollard website, seems to be jam packed, with 'money begging' kind of things. Just like other (typical dare I say), free energy websites.

Once free energy is brought into the equation, my spider sensors suddenly snap into overdrive, and I get rather sceptical of any experiments they claim to perform.
Don't get me wrong, free energy can/does exist. E.g. People staying in a hotel obtain it, for their energy consumption there, as they don't need to pay for it, as such. So, it can exist (end of sarcasm).
I like to keep an open mind, so rather than talk about it. As other(s) request. Just build a working model, and demonstrate it to suitably experienced and/or capable and/or qualified engineers, and let them verify (independently), what is going on,
After which, I will be delighted, to here all about how it works.
But if you/they can't demonstrate it, in the way I described, then why not ?
Sketchy video(s), imprecise documentation, lack of independent testing (as described above), etc etc. Doesn't persuade me.

If you want to persuade me, that free energy really exists. You would need extremely strong/robust and independent evidence, ideally from multiple sources. Not shaky video sources, from the same (to at least me), suspicious person (Eric Dollard).
Also, the so called expert or knowledgeable person/experimenter, in the other video. Keeps on talking about Mega cycles per second (or some other similar, ancient units). That makes him sound like a (potentially) unreliable electronics engineer, or Physicist, or whatever his knowledge base is suppose to be.
These days it would be Megahertz (MHz), and KHz (Kilohertz), NOT Kilocycles per second.
