As much fun as this could be I can't watch. It does not work.
There is ONE device that I know of and that is only because I know people w ho worked on it that can appear to give free energy. But it uses magnets an d the way it does it it saps their magnetic properties. It can supply your house with power for approximately seven years and then it is spent. It is no more perpetual motion or magic than a dry cell battery.
I can probably get you one. you can't build it as it costs a shit ton of mo ney in machining and some special materials that are not cheap. Before plac ing your order though take your electric bill for seven years and add it up and see if it adds up to about a million dollars. And if it does, the devi ce does not have the capacity to supply that much so you need a bigger one which will cost even more.
There is no free lunch. First law of thermodynamics, and science in general . You can't even measure something without affecting it and that includes t he entire universe. Even if you look at a star with a telescope you are aff ecting its radiation to the Earth. But that effect being so infinitesimal t hat it is neglibible does not mean it does not exist.
Even an electrometer or elecrostatic voltmeter affects what is being measur ed.
If you want perpetual energy look into geothermal or solar. It will last lo nger than you. Those are your choices. Either that or find a way to harness the tides. Some thought has gone into that, it would require some sort of floating weight that would move up and down with the tides. This would be v ery slow and have to geared up immensely to be of any use. Or, if there is a way to store it but stored water weight really doesn't work all that well , it has been tried. It works but not well enough to replace what we're doi ng now.
Wind and solar work but they are intermittent, you cannot count on it. ther efore you use batteries which are an environmental nightmare.
There just ain't something for nothing. That Hendershot guy missed class on the wrong days, probably out getting high. Not that I have anything agains t that, but I am, and so are others, absolutely sure that could not demonst rate it actually working. The device I mentioned, I grilled the guy for day s upon days before I even started research on how it could possibly work. W e actually got into a couple of loud arguments about it. I asked hundreds o f questions. But in the end I figured out how it works and it is not magic or anything "free". But I do know exactly why they never bothered to patent it. Simply no reason to.
To sum it up, there is no free lunch Grandma.
