SELF RECHARGING CAPACITOR?

[sdenne]

Capacitors setting on a shelf should have a resistor (shunt) across the terminals, while they are in storage on the shelf to prevent accidental discharge when picking them up off the shelf. They develop dangerous charges just setting there.

that is wise to know this to be safe.

and helps to understand a little how capacitors are capable of recharging due to atmospheric conditions.


and thanks for the links mentioned above about electrets.

What's described here is an "electret", the electrical field analog of a "magnet".
It is in fact in common use today, in microphones, loudspeakers, Jefimenko slot motors, and so on.

Carnauba wax works well, you can make electrets easily at home using the HV from your tube TV's anode voltage. Carefully.

The energy that Eguchi extracted from his electret most likely came from his motions, charging and discharging the electret plates.

As you may or may not be aware, the earth's atmosphere is a gigantic capacitor. At its upper level, air molecules are constantly being ionized and then as the air circulates, the charge is eventually carried to the ground which has a negative charge with respect to the upper atmosphere.

Another source of atmospheric charge is condensing water vaper. As water evaporates, it gathers electrons the molecules in the liquid state are sharing, and leaves behind a positive charge. When it condenses in the atmosphere, it gives back the electrons creating a negative charge. This is why the cable generator's output increases in stormy weather.

Ham radio operators will certainly confirm that a coaxial cable strung out as an antenna will pick up static charge, especially in wet, stormy weather.

BE SURE TO WEAR RUBBER GLOVES WHEN EXPERIMENTING WITH HIGH VOLTAGE, IT CAN KILL YOU. USE ONE HAND TO HANDLE IT WHEN YOU CAN. SO IT WILL NOT GO THROUGH THE HEART.
