Negative discharge effect

This experiment, it doesn't work any more, it looks like as if it were some paranormal phenomenon https://archive.org/details/ndischarge

Hi folks! I succeeded to repeat the experiment. The effect was less than at previous time though, and appeared on another frequency. What it depends on, i don't exactly know. The video about this repeating the experiment is the last on that page, number 4. The circuit is also now simpler:

I wish I could figure out what you are getting at. You are using a frequency generator and a mosfet to charge a capacitor? Can you please explain, and can you please put a real drawing of your actual circuit somewhere where it can be examined? The text diagram doesn't mean much to me.

The mosfet's own capacitances will pass power quite well from Gate to Source or Drain, even if the Gate isn't leaking, when the right frequencies are used. It's a mistake to assume that a mosfet Gate drive signal is completely isolated from the load side of the circuit.

The circuit diagram is in the video, but i will try to upload the original diagram also to the archive.org page.

Basically yes, there is a capacitor, a coil and a diode, and there is only switching, no external power source, yet voltage appears on the capacitor.

I'm well aware of the mosfet leaking, or maybe what i call leaking, you call capacitances passing power, but this is what i mean by mosfet leaking.

I did everything to measure the mosfet leaking, you see if you see the videos. I even tried to measure the input current of the mosfet, but it is infinitesimal, thus difficult to even detect. I used a circuit which had only one capacitor, no coil, and by measuring the voltage on the capacitor found that any mosfet leaking which there can be, can only cause more than 100 times less power than the power generated as an output. This was also done with the same frequency and duty cycle as the experiment.

But whatever mosfet leaking there is, all will end up in the capacitor. The mosfet's output capacitance empties itself to the circuit in each switching cycle. So the more frequent is the switching, the more the mosfet leaks, there is nothing more special to it in my simple mind. Thus with the ten times lower frequency the mosfet cannot leak more than with the ten times higher frequency.

To be more certain, one certainly may measure the leakage on different frequencies, but i don't think that it gives much more. In the last video i made a leakage test only by measuring the voltage on the capacitor with the frequency on which the effect clearly didn't work. Why i made only that test, is because i don't want to make people to do a test with only a mosfet and capacitor. Because this is dangerous and creates a condition similar to short circuit, which is a quick way to burn the mosfet and maybe even the signal generator.

Mosfet is very good for such applications. Some say mosfet switches faster than a transistor and its input power and leakage is much less than that of a transistor. When meaning by leakage both the capacitance leakage (or passing power) and current leakage.

Tried to draw it up, you can check it.
Personally I think its drawing from your micro controller but just my opinion.
