Energy comes from kinetic energy, and another is force. Solar energy, wind energy and water energy between heaven and earth belong to kinetic energy. There are also bioenergy, geothermal energy, lightning, tides and so on, which are not used much. We mainly use electricity today. Because it is practical and applicable. Every substance has energy, nuclear energy and molecular energy.

Nuclear energy is undoubtedly powerful, even the most powerful. But I personally think that the mode of civil energy is the best. After all, the world's optimal structure and energy utilization are embodied in animals and plants. All models that don't use perpetual motion machine as power source are flawed.

How biological energy is formed. There are basically three main parts. Sunshine, magnetism, matter. Magnetic substances will change under the influence of temperature. The magnetic force decreases at high temperature and increases at low temperature. Magnetic force can attract not only iron, but also water and many things. Just like gravity. Magnetic force comes from structure, so it can be created.

Al-Ni-Co was produced in the 1920s. Subsequently, ferrite was made in the 1950s, and rare earth magnets, including NdFeB and samarium cobalt, were made in the 1970s.

Temperature affects magnetic force, which can affect ion flow and generate electricity. Ion flow itself is material exchange, which can also trigger chemical reactions. Chemical reaction will cause temperature change, which will change the magnetic force and cause ion flow to generate electricity. Perfect cycle.

Another relatively stable and inexhaustible energy source is geothermal energy. This energy is undoubtedly powerful.

About gravity. When I saw the astronauts floating, I thought about how to be as stable as on earth. Gravity is a downward force. Isn't it enough to provide a downward force? Is the downward flow of gas popular? I see. Magnetism. Of course you don't have to do this. Magnetic force is gravity. Originated from structure. Derived from magnetic elements. The element with strong magnetic force is the fundamental solution of gravity. Suppose a sphere.

The surface is covered with magnetic substances, and the gravity of the center of the ball cancels each other out. If they are put together, they form gravity, which can enhance or weaken the external gravity. It should be beautiful to use on spacecraft. This is the role of the moon, causing tidal phenomena.

Evolutionary computer. The limit of a computer is three-dimensional, and it still lacks two characteristics: density and speed.
