The word "gravis" in Latin into Russian means "heavy". The energy of gravity is the energy of the gravitational field, the very gravity that holds our planet near the Sun, prevents the earth's atmosphere from scattering into outer space and causes an apple ripe on a tree to fall down. It is said that it was the fall of an apple that led the great English scientist I. Newton, who was sitting in his garden, to the idea of the existence of attraction between any bodies of the universe. However, one can hardly guarantee the authenticity of this story, especially if one takes into account the considerable popularity of the apple as the hero of all kinds of legends, starting from Adam and Eve. But one way or another, the honor of discovering the law of universal gravitation, and even more so the mathematical derivation of the formula describing the magnitude of gravitational forces, really belongs to I. Newton.
People had to face the powerful manifestation of the gravitational field from the very first steps of their conscious life. True, the modern general theory of relativity, built by A. Einstein, provides an excellent mathematical description of the gravitational field, but the question of the physical nature of gravitational forces is still practically a blank spot in science. It is not surprising that the problem of gravity attracts a record number of "laurels seekers" who are not too sophisticated in the wisdom of modern physics. Various scientific institutions and editorial offices receive hundreds of hypotheses and projects, which cannot be published due to their groundlessness and incompatibility with many other firmly established facts and laws of physics.
Humanity has not yet been able to boast of great success in actively using and converting gravitational energy into the forms it needs. As an example of such a transformation, the operation of hydroelectric power plants is sometimes cited, the reservoirs of which are filled with water during tides caused, as is known, by the attraction of the Moon. However, if we look into it, it turns out that in this case we use the kinetic energy of the axial rotation of the Earth.
In fact, the operation of the mentioned power plants is based essentially on the use of tidal friction forces, the increase of which accelerates the process of braking the Earth by the Moon. At the same time, the gravitational potential of the Moon not only does not decrease, but, on the contrary, increases. By the energy of gravity, it is natural to mean the latent, i.e., the potential form of this energy. Another thing is that we will be able to use it, apparently, only by first converting it into a kinetic form.
Let me ask the reader, but don't the turbines of our conventional power plants rotate due to the potential energy of water falling down under the influence of gravity? Yes, this is true, of course, but let's agree, when talking about the use of gravitational energy, to keep in mind the irrevocable withdrawal of it in favor of a person from any system of interacting bodies. But in conventional hydroelectric power plants, we ultimately use the energy of the sun's rays. Indeed, it is the solar heat that evaporates water from the ocean surface and lifts it along with the heated light air. At this stage, some of the solar energy is converted into gravitational energy. And when water, falling in rain and flowing into rivers, returns to the bosom of its ocean, some of this energy, in turn, turns into electrical energy. At the same time, the status quo is being restored in terms of the gravitational balance of the Earth-Sun system. 1xBet Special Offer: Get an additional 100% sports bonus up to €130.
