Is there any mechanic devide that works?

This is all the little i know about that. A metal sphere or a toroid with a pin on it, gathers electrons from the air, and the electrons are pushed out through that pin. I think it works in Tesla coil so, it likely ionizes the air around that ball. But in Tesla coil the electrons are forced out of that sphere by current. I don't know that it causes any flow of electrons just like that, without any external force, and i don't know that anyone has ever found it. I think in that device, if it can ever work, there had to be two of these spheres with a pin. One towards the plates with the pin, and the other towards the plates with the sphere. This at least made sense to me. Though i doubt that without touching the electrons move from one object to the other, unless they are forced. If one can provide ant further evidence about all that, then that would be good of course.

I found it in youtube (https://www.youtube.com/watch?v=H-AqL-8RGNc )  comments. It could be useful for someone:


beforebefore    1 month ago    Some things to consider... and/or try...   First, consider this: Triboelectric charges:  https://www.trifield.com/content/tribo-electric-series/ (there are many of these charts available, and many have slight variances – determining this charge affinity is not an exact science)   Wood is nearly neutral, with a triboelectric affinity charge of around +7, Polystyrene is highly negative, at around -70... resulting in a charge difference of about 77.   Your version (as shown) has 0 difference... same materials throughout. The Styrofoam (foamed polystyrene) would have been a good material! (-70).  Teflon is the best, at -190.   The other guy's "disc" looks like corrugated polystyrene board... which is fairly common, called "corrugated plastic" or "plastic cardboard" at hobby stores, home depot, etc. Commonly used as front yard signs, supported by wire-frame supports. He may have used 2-3 layers, glued together to get it thick enough.   Van de Graaff generators are a source of info on electrostatic charge redistribution. Charge collectors use several pointed tips, often guys use frayed-out stranded wires for this, all trimmed to the same length.   I believe you may need to modify your "long curved conductor" a bit, getting rid of any sharp transitions, edges, etc. round-off every edge... wrap the copper foil over the edges... this is common-practice in electrostatic charge experiments... but then again, may not make any difference in this device.   It still seems (as already mentioned) that the charges need a path to flow... possibly there is a single 50-gauge hidden wire strand connecting the metal "charge redistribution" parts. Wood is a better conductor than polycarbonate... but not by much!   "Positive" charges tend to rise up, away from the positively charged Earth. He says as the conductive plates pass by the sharp conductors ("pointy things"), the alum. plates become Positively charged... and if so, they rise, causing spin (but opposite to the direction you spun this one in this video)    If this is what happens, the pointy conductors are taking a negative charge.   If this all holds true, then the long strip conductor then re-deposits the negative charges onto the foil strips (alum or copper, no matter), which causes that "side" of the disc to be drawn towards the earth.   HOWEVER... if this is what's happening, then the curved conductor should be located much higher on that "side" of the disc... in the upper-quadrant, not the lower-quadrant... so that it can re-deposit the negative charges sooner, causing more rotational torque. Likewise, even the "pointy" tips should be located lower on that side of the disc, giving the now-positively charged alum/copper plated more time to create upwards 'lift'... so to speak.   IMHO... and IF this thing really works... the "timing" should be such that the two charge transfers should occur 180° out of phase... if that makes any sense.
