Hi Andreas,
I found something here https://www.psiram.com/de/index.php/Gustav_Hans_Weber https://www.psiram.com/de/index.php/Gustav_Hans_Weber
It's in German and isn't the schematic I once saw. But it's the same person.
I found the schematic that I got of the self-runner and it is attached. This circuit uses a class X5R ceramic capacitor which has negative capacitance characteristic with increasing voltage. This looks like a perpetual motion machine of the second kind. I.e. it's converting heat into some other kind of energy (electrical energy and then back into heat and light through the lamp).
Regards
Ole

Hi Ole,
The imaginary part j or square root of -1 means reactive power. This has to be changed to active power without having to take active power from the source. A parametric change in capacitance ought to do this job as a decrease in capacitance at constant charge means increase in energy.
You mean
E = Q^2 / (2C)
? I just re(did) the integration to see where this comes from. The above work had to be performed (energy spent) to get a specific Q into a cap. The above equation is valid for constant C during the charge phase only! Charging a cap to a given Q with decreasing C requires extra energy as can easily be seen in the following equation:
W = Integral (q / C) dq
So we already had to do extra work to get the cap with the decreasing capacitance charged. Let’s assume we have some C charged to some Q now. How could the C further be decreased (after disconnecting the voltage supply)? The only way I see is by increasing the distance between the plates but this requires mechanical work!?
I don’t see the potential for FE in this. It may theoretically be possible if we could
• charge the cap at constant C
• then after disconnecting the power supply (constant Q) decrease the capacitance without having to apply mechanical work
• then discharge into a load
But these are many Ifs!? Where is the apparatus/concept that can do this. I see no potential at all! :-( Am I missing anything?
Thanks,
Andreas
