Err that is what I have been doing for decades but thanks for the suggestion. It is appreciated.
None of them I have built have worked. And by them I am not referring to the short list in that Kelly fellows pdf.
Granted that could be down to my inability or imperfect materials.
I am utterly convinced Viktor Schauberger managed to get working examples of his tech built and put to use, I sadly do not have the wherewithal to replicate his efforts. I still read through Callum Coates books explaining what Viktor did and at least a decade or two back there was a video on youtube of a young Dutch chap who went and visited Viktors last apprentice who had some of his devices at his home but either he did not know how they worked or he didn't want them shown working on camera.
The apprentice was an old man and will be dead now so where his devices ended up god knows.
Incidentally free electrical energy exists today. It comes through the wires connected to your house. The only reason the soul reason the sole reason you and I think it isn't free is because there is a meter in the circuit which tells us it isn't. Hows that for a con hiding in plain sight!
Edit to add
Here is the latest non working effort.
Replicating the content of this video.
Earths used were ground spike for left hand side and cold water pipework of an outside tap for the right hand side earth.
LED by itself in the sun produces 0.47v
LED in shade produces 0.39v
Ergo the LED is manufacturing electricity from light
The magnets did absolutely bugger all as did the earths
State of play
Nigel is not revealing ALL!
I am crap at building devices
The nails are not 6 inch, they aren't in the video!
The nails are not iron, they aren't in the video!
I am missing something hiding in plain sight "Now let's see how clever you are." he says right at the beginning of the video!
