What technologies can be expanded to benefit “free energy”?

The concept of "free energy" in physics is a description of the internal energy of a thermodynamic system, which can be used to do work on the outside, including the definitions of Gibbs, Helmholtz and Landau free energy. For most people, the concept of free energy is as messy and vague as the world of Flight of the Bumblebee.

Using free energy to generate electricity involves some incomprehensible and mysterious things done by many inventors; sometimes it represents the abandoned "perpetual motion machine"; sometimes it represents a kind of energy that can be obtained from nature for free or very cheaply, such as the familiar wind energy and solar energy; sometimes it represents water-to-oil technology, magnet power generation technology, or heat generation technology driven by the rotation of the earth, etc.
 

The earliest concept of free energy dates back to the end of the last century. In late 1880, the trade journal Electrical Science published an article predicting the emergence of free electrical energy in the near future, and the amazing discovery of electrical energy became ubiquitous. Nikola Tesla demonstrated that a light bulb could be lit by a high-frequency electromagnetic field, and people were full of exciting imaginations about unprecedented phenomena.

In the next 20 years, cars, airplanes, movies, tape recorders, telephones, radios, and cameras appeared, and people who had passed through the Victorian era began to be surrounded by all kinds of new things.

For the first time, ordinary people can look forward to a utopian future where people can freely use transportation, communications, housing and the jobs they like, and everyone can have a piece of the pie in the future.

But what does the real world look like? Has free electricity emerged in today's technological explosion? Has the exciting prediction of free electricity been confirmed by real science?

The answer to this question is no, there is no free energy available. It is just that with the advancement of technology, the cost of obtaining electrical energy is becoming lower and lower.

Most of the new discoveries of "free energy technology" now adopt a new and confusing form. They claim that they can obtain greater energy output without using energy, or using very little energy, including but not limited to the following categories of technology:

(1) Radiant energy: This type of free energy technology claims to be able to obtain this type of radiant energy from the surrounding environment through the so-called "distillation separation" technology; some schemes claim to be able to harvest the free energy of quantum fluctuations in the vacuum.

(2) Permanent magnet power generation technology: The core of this type of free energy technology is to generate more electrical energy in the coil than the energy required to drive the permanent magnet through the magnetic field generated by the permanent magnet, or to generate more heat in the metal through eddy currents.

(3) Mechanical heater: Objects moving in a liquid will be subject to a damping force, which will in turn do work on the liquid. This part of the work energy is converted into thermal energy of the liquid. This type of free energy technology claims that through specially designed mechanical devices, more than ten times the input mechanical energy can be generated in the liquid, based on which energy can be infinitely amplified.

(4) High-efficiency electrolysis technology: Water can be decomposed into hydrogen and oxygen through electrolysis. The combination of hydrogen and oxygen will generate electrical energy or heat energy. This type of free energy technology often increases the efficiency of water decomposition by adding some mysterious electrolytes or catalysts, making the energy used for decomposition lower than the energy generated by the re-combustion of hydrogen and oxygen.

(5) Vortex energy: Modern internal combustion engines mostly rely on the high pressure generated by fuel combustion to push pistons or fan blades to generate energy. Low-pressure work also exists in nature, such as hurricanes, which work through the adsorption of low pressure or vacuum. As a result, a large number of technologies claiming to be able to use vortex energy to generate electricity without consuming fuel have emerged.

(6) Cold fusion technology: The originator of this technology was in 1989 when two chemists from the University of Utah claimed to have achieved nuclear fusion in the laboratory. Although it was proven to be false six months later, this idea ignited many technical ideas for developing free energy.

(7) Solar energy efficient heat pump: The refrigeration efficiency ratio of ordinary household refrigerators can reach more than 3, that is, for every one part of electricity consumed, more than one third of the heat energy can be transferred from the refrigeration room to the environment. In some schemes using solar energy heat converters, the heating efficiency can be increased by 8 to 10 times. It seems that there is energy amplification, but it is just the transfer of energy between different forms, which does not mean that the energy available for work has increased.

The development of human society has an urgent and huge demand for energy, especially clean and cheap energy. Generation after generation of scientists have been making continuous efforts to this end, and many technologies, including the use of thermonuclear fusion, have been gradually improved. However, the so-called free energy power generation technology in the previous video is not as effective as it appears. You can just regard them as magic that can be used for entertainment.
