How can we convert gravity into energy?

Storage systematics Common storage divisions give the impression of completeness and make it more difficult to examine and discuss the non-established storage types in an open-ended manner. Almost all well-known storage studies use, for example, the group “mechanical storage” and summarize the three storage types pumped storage, compressed air storage and flywheel storage. As the following storage system shows, these three types of storage are based on completely different physical forces against which work is performed. The classification of the basic physical forces can be used on the upper level as a classification feature for a consistent and comprehensive system of all types of storage. The RauEE Foundation proposes a scientific study that revises and supplements the following draft of a storage system. Summary of the basics: Gravity is freely available anywhere on earth. Electrical energy can be converted into potential energy and recovered again. The following applies: 1Nm = 1Ws The potential energy on the surface of the earth is sufficient for the equation: EP. = m * g * h The stroke of a mass carrier of 1 kg by 1 meter generates potential energy of 9.81 Nm or 9.81 Ws. With this simple rule of thumb, the energy content of lifting power plants and lifting storage power plants can be estimated quickly: 1 t mass * 1 m stroke = 9,810 Ws = 2.72 Wh potential energy Example: A concrete cuboid with the edges: 10 x 5 x 3 m has a volume of 150 m3. That corresponds to twice the volume of a sea container. It weighs approx. 368 t. If you lift such a cube by 100 m, it contains a potential energy of 100 kWh Properties, light) - the weak interaction (binding force between protons and neutrons: atomic nucleus, nuclear force) - the strong interaction (binding force of elementary particles: structure of protons, neutrons) The four basic forces of physics describe all manifestations of our universe. Gravitation describes the attraction of bodies that have a mass, from the smallest speck of dust to the planets to the largest galaxy. Gravitation is the origin of all forms of energy accessible to us. On the sun, hydrogen atoms fuse under very high pressure to form helium atoms and release binding energy from protons and neutrons. (Nuclear foot) The electromagnetic radiation that is generated hits the earth in the form of sunlight. However, the gravitational force in the sun is not enough to produce elements heavier than helium. It is now believed that the heavy elements such as gold, lead and uranium were formed in huge galaxies with a mass many times higher than that of the sun or the Milky Way. It holds every body on the surface of the earth and pulls it to the center of the earth. Gravity ensures that we can move around the earth in the usual way. Gravity is available to everyone anywhere on earth free of charge. In free fall (assuming a vacuum), every mass carrier becomes a spring, a stone or a raindrop with the acceleration of gravity of g = 9.81 m / s2 accelerated towards the center of the earth. The force of gravity that causes the fall is at the surface of the earth: Gravity: FG = m * g (FG= 9.81 N = 9.81 kg * m / s2) Potential energy Energy is the ability to do a job. If you lift a weight on the earth's surface by 1 m, then F is against the force of gravityG a lifting work WH to perform. We feel this when, for example, we climb a hillH = FG* h = m * g * h As we experience it in ourselves, every body falls to the center of the earth. As soon as the body is released, the lifting work WH to be recovered. This ability to do work is called potential energy EP.. It is just as large as the lifting work W performedH If a weight of 1 kg is lifted by 1 m on the earth's surface, the potential energy is: 1 kg * 9.81 m / s2 * 1 m = 9.81 Nm Energy conversion Electrical energy arises from other types of energy and can be converted back into others. The principle of the conservation of energy also applies to them. It states that energy can neither arise nor disappear in a closed system; potential energy, electrical energy and thermal energy are equivalent, i.e. they can be converted into one another. The following applies: 1 Nm (Newton meter) = 1 Ws (watt second) = 1 J (Joule) Conversion losses The conversion of potential energy into electrical energy takes place with the help of mechanical and electrical devices that emit energy to the environment due to friction or radiation. Every conversion process is therefore associated with a loss of usable energy.Lifting storage systems use gravity
