The output is DC not AC, the Kapanadze device is 220 VAC at 50 Hz.
Putting the piezo device with washers in the coil would require 220/10=22 units.
It would require a strong magnetic field vibrating at 50hz, where did the current to generate the magnetic field come from?
From the transformer? The transformer winding is 17 ohms. The current has to come from the transformer.
No, not from a transformer. Kapanadze's device creates a 26-amp current in the load! This current can also be used to create a magnetic field in the coil.
The output current can flow through this blue coil, wound with ordinary electrical wiring.
Imagine the blue coil on the plastic tube connected in series with the load and the hidden "piezoelectric elements" inside. The current flowing from the "piezoelectric elements" creates a magnetic field that compresses and expands the "piezoelectric elements" inside the coil. The magnetic field can act on iron washers with springs or magnets, producing the necessary vibrations. Vibratory pumps for coffee machines operate on a similar principle. This small device creates pressure pulses of up to 20 atmospheres while consuming only 50 watts.
Thus, a device consisting only of a coil, its internals, and a powerful load can be a self-sufficient oscillator!
The other components seen in Kapanadze's video may only be necessary for starting, maintaining the required frequency and voltage, and supplying the necessary components for the continued operation of the device.
In general, Kapanadze's device, in its simplest form, requires very few components other than the coil itself.
Not all of the wires in Kapanadze's video may be real wires. Capillary copper pipe, similar to those used in refrigeration, can easily be disguised as wire.
At the output, the load may have a nearly normal alternating current, since during the mechanical relaxation phase, when the "piezoelectric elements" are not generating current, the coil can discharge into the load, creating a pulse of opposite polarity, acting like a regular electrical choke.
This is what will revolutionize our understanding of Kapanadze's device:
- Watch this video at 12:43. The power to the generator is completely disconnected, as are the transistors and everything else in and around the jar, is de-energized.
And what do we see in the next few seconds? Without external power, the coil continues to generate 25 amps of 220 V for several seconds, without any power supply from the output. A strange sound is heard, likely due to 50 Hz desynchronization.
