Radiant Energy: Vacuum Tube produce Cold Electricity

Cold electricity is closely related to the spark gap. A typical electrical circuit to create a spark gap is a hairpin circuit. Vacuum tube is mainly used to amplify signals in electronics.
Classic vacuum tubes have a few characteristics that resemble the spark gap, especially the important similarity of the Plasma state when they operate.

1 . When does cold electricity appear? And what is it actually?

#1 The appearance of cold electricity

Cold electricity appeared and was mentioned by Nikola Tesla in the hairpin circuit.
Here is the classic hairpin circuit:
Tesla first described the Hairpin circuit during his 1891 lecture in New York:

Figure 1. First mention of Hairpin circuit by Tesla during his 1891 lecture

In that circuit, there was a spark gap. When the coil is transformered by an alternating current, the capacitor is charged and discharged. During the discharge process, spark gap will appear ignition.

The filament bulb will glow with white light, while the U-shaped copper bar will be short-circuited. The power supplied to this filament bulb is "cold electricity". This is not an electrical current with an Electron current flowing through a light bulb.
Watch this video to see how the refrigeration is lit from the U-shaped copper bar:

#2. What is the nature of cold electricity?

If we want to know the true nature of cold electricity, we need to accept that the speed of light is not the speed limit in physics. This is the problem that Tesla addresses in his theory. However, "faster than the speed of light" means that relativity and some problems in current quantum theory need to be rearranged in science. This has not happened, and of course, the Aether doctrine in physics has been abolished to ensure the status of today's doctrine.
In other words, the nature of refrigeration is in the theory of Ether (Aether) of Tesla. But, the secret was buried in the tomb along with Tesla. Some scientists (descendants of Tesla) have researched and developed "cold" electricity, but it remains a mystery.
In terms of expression: cold electricity is a manifestation of radiant energy. Tesla and its scientists refer to radiation energy more than cold electricity. In other words, cold electricity is a manifestation of radiant energy.

Radiant Energy:
In 1875, Sir William Crookes discovered the properties of Radiant Matter. His invention of the Radiometer was proof that Radiant Matter was a constituent of sunlight. Nikola Tesla, following up on these discoveries, found that electrostatic charges could also be conveyed by Radiant Matter. He called it Radiant Energy. When Radiant Energy was transmitted from place to place, it behaved like “sound waves of electrified air.” By 1900, Tesla had developed lighting systems and electric motors that ran on Radiant Energy. By 1934, Thomas Henry Moray had demonstrated a small box that produced 50,000 watts, running on Radiant Energy. In 1973, Edwin V. Gray started demonstrating his EMA motor, an 80hp electric motor capable of keeping its own batteries charged while delivering surplus mechanical energy. And Paul Baumann built numerous models of an astonishing self-running machine called “Testatika” in Switzerland in the 1980’s. Much of John Bedini‘s work also falls into the field of Radiant Energy. These developments are only the tip of the iceberg in our knowledge of what is mistakenly referred to as “static electricity” but is really something much more astonishing.
I see that quite a lot of electrical engineers have made their own generators - harnessing radiant energy (refrigeration). Ordinary people (not electrical engineers), they have been educated with general knowledge, and therefore, they do not know that cold electricity has been exploited.

Especially: Radiant energy can be clearly seen in Tesla coils. And this power-gathering device is needed.

2. Vacuum tube produce cold electricity

Vacuum tubes of many types, the best known are probably Triode vacuum tubes.
One thing for sure is that the spark gap should be placed in a vacuum tube. Because spark gap requires interruption during ignition. The gap of spark in the air will create ionization phenomenon, reducing the possibility of disruption.

Tesla had the idea to put the spark gap in a vacuum tube so that the interruption work was done well.
This type of vacuum tube contains spark gap (see picture):

- Consider the type of vacuum tube Triode:

This type of vacuum tube is used to amplify signals in electronic engineering. But one thing is that in the vacuum tubes, all contain the Plasma mystery. The spark gap also has Plasma, the Triode vacuum tube also has Plasma - this is something for free energy learners to keep in mind.

- Consider Plasma and vacuum tubes:

In Plasma, there are many mysteries. With a spark gap, Tesla was able to block the transfer of electrons and then capture and route the Ether that was tuned to electric charge. He considered these Ether particles to be able, when freed in a special spark gap, to travel FTL, which while moving, or trapped in a dielectric material, would not recombine with electrons, or more likely generate new electrons. If it slowed or got trapped on (it traveled on the surface of the conductors) a conductor, then it would create electricity.

Note: FTL = Faster-than-light
