The following post and image was posted by Tom Kaminski in reference to the earlier post about the “Vacuum Capacitor” developed by the Russian group Freel Tech (see more here)
I have built a replica of what I think is the device. Here is a picture of the setup:
I put the tube into a stainless steel tube (cigar holder) filled with silicone oil:
Here is a schematic:
The resistor was adjusted to 10 ma. At 10 ma, there is a 2.5 volt drop across the tube with the plate connected. The current drops to a few microamps when the plate is disconnected and placed in the silicone fluid.
I am letting it “age” with the pulsing full-wave DC applied.
