For me, that link goes to 'Reviewing Free Energy Generators. A Response to My Video "Nikola Tesla's Greatest Invention"- 102'. Was that the video you intended?...
The link was intended, but I can see how it was confusing. In that video there is a lot of talk about how and why people would fake free energy (ish) devices, which I found relevant.
A possible problem with this invention is that it seems to be based on the electrical potential difference at different heights. There is another non scaleable way to use that.
You fly a kite and put some special shape stuff on the kite (spikes and something I think), and a wire down to earth, and you get a current. Problem is, while there is a potential
difference, you don't have to pull much energy out of the system before the potential difference goes away. It's like having a dam for hydro power with very little water.
There are some videos about the kite thing which explains this in great detail. Until a large scale test has been performed, I'll assume that "your" invention has the same problem.
I am still trying to rap my head around what makes it work. If atmospheric potential difference, then why do they get a result from 15cm. I thought triboelectric after watching vid…
I have no idea. I don't even know what triboelectric is. I thought pointing to that other experiment strengthened my stance of "we still don't have enough data to know this is useful"
Thou shalt not read papers. Thou shalt halfread a headline or two, then thy shalt present thy first impression as Absolute Truth and verbally attack everyone who do not submit to it.
If the thing is practical I think making it transparent should be a relatively easy task, though maybe not as simple to DIY with simple household items?
