Who discovered Zero Point Energy?

I have searched a lot of documents, but it is still not clear who invented zero point energy.
But I can disclose information:

1. Who is the person who understands about zero point energy the most deeply
2. Has zero point energy been applied yet?

A . Why can't find the inventor of Zero Point Energy? Meanwhile, Zero Point Energy is cited a lot.

Reason:

1. There has been no official announcement about the exploitation of Zero Point Energy in scientific circles
2. Science proves that Zero Point Energy can be exploited - This is why Zero Point Energy is cited a lot

Why is trendy science (quantum physics) still debating the exploitation of zero point energy?
Quantum theory and general theory of relativity, it belongs to modern science. But both are incomplete.
Science is never complete. Kurt Godel's imperfect theorem proved.
But, things won't be in trouble without the presence of the Electric Power Industry.
This is the investment of the electricity industry and government for scientists, the purpose is to destroy the theory of Ether in physics:

A History of the Theories of the Aether and Electricity, by Sir Edmund Whittaker (1951 revised and enlarged second edition, Vols. I and II).
The 1910 first edition of this book was probably the most comprehensive book ever published on ether theory as it existed in 1910, but the 1951 revision merely clarified “acceptable” ether physics. The first edition was printed in Scotland, under the title A History of the Theories of the Ether and Electricity, from the age of Descartes to the close of the nineteenth century.
The second edition incorporated “new material” related to quantum mechanics. Classical theory was in Vol. I, while Vols. II and III gave the origins of relativity and quantum theory up to 1926. Neither the 1910 first edition nor the 1951 revision mentioned Tesla, but the chronological sequence appeared to be “skewered’ in the revised edition, with little or no attempt to point out what the scientists were actually aiming at in terms of electropulsion. Though information regarding Nikola Tesla was omitted, there is much valuable related information.

Why should they suppress the Ether doctrine?
Because, with Tesla's Ether theory, it is possible to create energy from nothingness - invisible energy in the universe.
The suppression of the electrical energy industry (Power monopoly) on Ether, is also the suppression of Free Energy.
Of course, the government and the Electricity industry have a close relationship. Money and politics are intimately linked in every age.

B. Who is the person who understands about Zero Point Energy the most deeply

Although zero-point energy is usually regarded as a quantum phenomenon and a consequence of the Heisenberg uncertainty relationship, the existence of zero-point energy was inferred by Einstein, Planck, Nernst, Nikola Tesla, and others in the context of blackbody radiation prior to the discovery of quantum mechanics.
Einstein and Otto Stern came close to deriving the blackbody function without assuming quantization but with the presence of zero-point energy. Nernst in particular claimed in 1916 that the universe was filled with zero-point energy. This line of investigation was abandoned with the advent of quantum mechanics, but the concept of zero-point energy soon reemerged with a quantum interpretation.
Who understands the most?
It was Nikola Tesla. However, in the context of the gravity of money is stronger than Zero Point Energy, forcing him to be silent. Learn more: Free Energy Massacre - Free Energy Surprise - Occult Ether Physics
If Tesla captures Zero Point Energy, he will know how to exploit Zero Point Energy

C. Has zero point energy been applied yet?

Tesla's free energy generator, which aims to provide cheap (free) electricity to the whole world, has failed. Failure in practical application and commercialization. The complete blueprint for wireless power, global power supply, may be complete. But then stolen after he died.

Generator from Zero-Point Energy, was successful on a small scale. That is, powering small motors, or powering homes.
Evidence for this statement:
Proof 1: Flying saucers
The design for the flying saucer was successful (complete). Tesla kept that blueprint. The power supplied to Tesla's flying saucer is the energy derived from Zero-Point Energy. Flying saucers work according to the theory of Ether, which means there is no gravity in Ether. So no need for jet engines.
The energy supplied to the flying saucer is a self-sustaining generator, the energy is taken in nothingness - Zero-Point Energy
The government fabricated UFOs - aliens, to conceal Tesla's flying saucer technology. Germany and the United States are the two countries that own Tesla disk technology.

Proof 2: Descendant of Tesla
Evidence 2: Scientists who admire Tesla have successfully developed a way of extracting electricity from Zero-Point Energy, even though the document about Zero-Point Energy has been greatly lost.
