Based on the universal gravitational theory learned from the apple landing phenomenon of Newton , we know that the circulation of water in nature is caused by the earth's gravity as the force and electromagnetic force (certified by the kite electric capture experiment from Franklin -1752 and the Zhou Jianghua-2010 discharge vehicle experiment) as the result of the contradiction between the reaction force interaction. The essence of human utilization of water energy is mainly to cut magnetic inductive lines by the water flowing from high to low under the action of gravity, thereby generating electrical energy. By the same token, can we directly use the ubiquitous and omnipresent gravity to "impact" the generator rotor to cut magnetic inductive lines to generate electrical energy without the need to use the media of water?

The gravitational energy discussed here refers to the infinite natural energy provided by the transformation of all matter in the universe due to the effect of force. Realizing the direct use of gravity energy is the dream of countless scientific research experts. It requires a high-level scientific world outlook and dialectical thinking method to be expected to achieve it. For a long time, many people have been committed to the study of gravitational energy, trying to develop and utilize gravitational energy, an inexhaustible infinite energy, but it is difficult to succeed. In this regard, scientists further pointed out that universal gravity has conservative characteristics, and any utilization of conservative gravity cannot avoid the situation where the potential kinetic energy conversion work is always zero. However, it is actually not feasible for us to view this problem from this one-sided metaphysical perspective. In the view of the extremely smart Einstein , he believes that universal gravity is not a force, but a space-time bending effect (this is the result of borrowing the concept of "space-time bending" invented by Einstein to extend the exploration of gravity characteristics). In a straight universe, gravity is linear, and due to the bending effect of space-time, gravity becomes a nonlinear bending characteristic. Although whether Ai's "space-time bending" theory is accepted by the world, there is one thing that space-time bending leads to the nonlinear manifestation of gravity, it can bring some unexpected inspiration to our direct use of gravitational energy: that is, when all objects on the surface are created, as long as they create the curved space-time proposed in Einstein's general theory of relativity, they can find that in this curved space-time, when it is determined that a fixed fulcrum and a lever constitute the motion pair at a certain relative height, under the action of gravity, the lever will change from the original linear motion to a curved motion, that is, a half-circumferential curved motion around the fixed fulcrum. This shows that the authoritative view of the original academic community that gravity is linearly perpendicular to the ground and moves in a straight line is different. When establishing a fixed fulcrum and an Archimedes lever to form the movement pair at a certain relative height and creating a curved space-time, the lever will move half-circumference curve with the fixed central fulcrum as a certain equal length radius, rather than a straight line. In fact, this is a well-known natural fact. A simple pendulum motion test can directly verify the existence of space-time bending effect. Under the action of gravity, single pendulum will move continuously from point A at a certain relative height to points B and C until it stops. As shown in Figure (1-1): (R=1.50cm)

From the above half-circumferential curve motion made by the single pendulum under the action of gravity, if you want to always utilize the infinite energy provided by universal gravity, you must always keep the single pendulum moving from point C to the starting point A at a certain relative height under the action of a certain natural force, so that it has a relative position of gravitational potential energy, so that it can continuously move downward to create energy to achieve work. How to solve this controversial problem? Some scholars point out that when an object moves downward in a half-circumferential curve, it is converted from potential energy to kinetic energy to store energy, and then use the stored energy to convert it into kinetic energy as a way to push the object to return to the starting point A along the "original path" points C and B, and then move back and forth. Through calculations, it is known that the total work done by converting the potential energy into kinetic energy and then from kinetic energy to potential energy, and the total work is zero, so doing this is futile.

Through calculations, it is known that the total work done by converting the potential energy into kinetic energy and then from kinetic energy to potential energy, and the total work is zero, so doing this is futile.In order to avoid the situation where the work is always zero, it is necessary to choose to take the "opposite path", that is, points C and D, until the starting point A. The kinetic energy required for this path from point C through point D to starting point A must be provided and accomplished by some natural force that has the opposite direction to the gravitational properties.

According to the contradictory movement law of the opposite and unified of the action force and reaction force , it establishes a dynamic mechanism and principle of the reaction force with the conservative gravitational properties that have an opposing and unified contradiction in the direction of the action force, so that the single pendulum can utilize its potential energy under the action of gravity. Because under the action of gravity, a single pendulum only completes one and a half-circumferential curve movement, to complete the entire circular motion, a certain non-conservative natural reaction force must be required to complete the other half-circumferential curve movement. What kind of natural force should be used to complete the other half-circumferential curve movement? Judging from the natural forces discovered by humans, among the types of natural forces, there are four forces: gravity, electromagnetic force, strong force and weak force. Among these four natural forces, since the latter two forces occur in the nucleus of , the force range is very short, and it is very difficult to use. Therefore, only the first two natural forces can be used, but the direction of gravity's action is always pointing to the center of the earth, and the direction of electromagnetic force can be artificially specified. Therefore, only electromagnetic force is the dynamic mechanism and system that establishes the unity and contradiction of the composition and gravity's action in the direction. Only by combining electromagnetic force and gravity in the motion system formed by bending space-time proposed by Einstein's general theory of relativity can the mutual conversion and utilization of gravitational energy and electromagnetic energy be achieved.

In order to more vividly and intuitively clarify the principles of mutual conversion and conservation of gravitational energy and electromagnetic energy. Below, we will use a two-dimensional plan diagram (1-2) to analyze this principle. As shown in the figure:

According to Einstein's theory of space-time bending effect, in the conservative gravitational field , we can assume that two fixed fulcrums O1 and O2 are established respectively. Two driving wheels and driven wheel trains of different sizes consisting of fulcrums O1 and O2. They are 2:1 speed ratio engage relative motion . In the case of no action and reaction force, both wheels remain stationary. This is because, although the driving wheel and the driven wheel system have a contradictory and contradictory movement relationship between the opposite and the reaction force, since the two wheels are subjected to gravity and support force respectively, the two forces are equal in magnitude and opposite in the direction, and the action points are perpendicular to the straight lines from the ground to the fixed fulcrum O1 and O2 respectively, which is subject to Newton's third law of motion , that is, static equilibrium. So both remain still. Therefore, gravitational energy can be utilized only by establishing a power balance and urging one of the driving wheels to mesh and drive the driven wheels.

First, we must constantly break Newton's static equilibrium and the conservation of energy in static (i.e., the content of the third law of motion in Newton's mechanics is regarded as "static equilibrium") [2], and re-establish Newton's dynamic equilibrium and the conservation of energy in dynamics (i.e., the fourth law of motion derived from Newton's third law of motion in static (i.e., the fourth law of motion derived from Newton's mechanics is regarded as "dynamic equilibrium"). Judging from the schematic diagram (1-2), the initial ones remained still. This does not mean that they have no force and reaction force, but because the two forces act "commonly and one line" to cause them to remain still, and the positive and negative energy offset is zero, so a dynamic balance is needed and two interactive forces and reaction forces are exerted.

Second, be sure to follow Newton's fourth law of motion, namely the "law of permanent dynamics" [3], the driving wheel uses the driving wheel to generate rotational motion under the interaction of electromagnetic force and gravity, and drives the driven wheel through meshing to achieve relative motion.

Suppose A1B1 is the displacement vector of the driving wheel moving from point A1 to point B1 by a finite F1 electromagnetic force, and B1A1 is the displacement vector of the driving wheel moving from point B1 to starting point A1 by a finite F2 gravity. .A2C2 is the displacement vector of the driven wheel from point A2 to point C2 equals F3 under the action of the gravitational force of F1 and makes a half-circumferential curve motion in the direction of gravity. C2A2 is the displacement vector of the driven wheel from point C2 to starting point A2 and makes a half-circumferential curve motion in the direction of gravity. The driving wheel is composed of an electromagnetic drive device as an active system, while the driven wheel is a driven system and is composed of a power generation device.The two-wheel trains are meshed at a 2:1 speed ratio. According to the conservation of kinetic energy, it can be derived. The electromagnetic energy E1 consumed by the driving wheel A1B1 using the electromagnetic force of F1 to perform half-circumferential curve displacement movement is equal to the energy E2 created by its B1A1 to perform half-circumferential curve displacement movement under the action of F2 gravity, that is, E1=E2. The energy E3 consumed by the driven wheel A2C2 under the action of the half-circumferential curve displacement movement under the action of F1 electromagnetic force + F2 gravity is equal to the energy E4 created by its C2A2 under the action of the half-circumferential curve displacement movement under the action of infinite F4 gravity, that is, E3=E4. Since the two wheels move relative to each other according to the speed ratio 2:1, it can be seen through the calculation that the total energy of the driving wheel completing a weekly curved displacement movement is the sum of the energy E1 consumed by the electromagnetic force of F1 and the energy E2 created under the action of the gravitational force of F2: E1+E2, which is equal to the E3 consumed by the driven wheels A2C2 and C2A2 for each half-circumferential curved displacement movement: E4: E1+E2=E3=E4, respectively. That is to say, the sum of energy consumed and created by the driving wheel completing one weekly curved displacement movement is exactly equal to the energy consumed and created by the driven wheel completing the half-circumferential curved displacement movement. The mutual conversion relationship between them is as follows:

Suppose: It is known that the speed ratio of the driving wheel O1 and the driven wheel O2 is 2:1, and the displacement vector A1B1=B1A1=A2B2=B2C2=C2D2=D2A2, A1B1+B1A1=A2C2=C2A2, F1 electromagnetic force=F2 gravity, E1 electromagnetic energy=E2 gravity, A2C2=C2A2, A2C2: F3 = C2A2: F4 gravity, E3 electromagnetic energy=E4 gravity

Because: A1B1+ B1A1=A2C2=C2A2, 2A1B1=A2C2 or 2B1A1=C2A2, F1 electromagnetic force+F2 gravity=F3=F4 gravity, E1 electromagnetic energy + E2 gravitational energy = E3 electromagnetic energy = E4 gravitational energy

Find the situation of the two wheels repeating motion: A1B1, F1 electromagnetic force, E1 electromagnetic energy

Solution:

1, ∵ A1B1+ B1A1= A2C2=C2A2

∴A1B1= C2A2-B1A1

or A1B1= 1/2C2A2 (Conservation of Angular Momentum)

2, ∵F1 electromagnetic force + F2 gravitational = F3=F4 gravitational

∴ F1 electromagnetic force = F4 gravitational—F2 gravitational

or F1 electromagnetic force = 1/2 F3 = 1/2F4 gravity (according to Newton's fourth law of motion (permanent dynamics law), that is, the "interactive mechanism of two points of action" and its "sum principle of the sum of two forces whose angular kinetic energy combined force is non-zero") [4]

3, ∵ E1 electromagnetic energy + E2 gravitational energy = E3 = E4 gravitational energy

∴E1 electromagnetic energy = E4 gravitational energy - E2 gravitational energy

or E1 electromagnetic energy = 1/2 E4 gravitational energy (conservation of kinetic energy)

Because the driving wheel moves in a half-circumferential curve in the reverse gravitational direction, electromagnetic energy is limited, that is, when it completes the half-circumferential curve in the reverse gravitational direction, the energy has been exhausted. After that, when it wants to cooperate with gravity to perform the next week and perform cycles of movement, it needs to provide and replenish the energy created by the driven wheel under the action of gravity, so that the energy is always conserved in the transformation movement. In this energy transformation movement, in addition to satisfying its own self-sustaining cycle, part of the electromagnetic energy can also be used to do external work.

At present, from the perspective of understanding the experiments and research and development of the mutual conversion of gravity and electromagnetic energy in China (reference: https://m.youku.com/mid_video/id_XOTU2NDA5ODg0.html?scene=shortplayMode=pugvsharekey=7ced16ae5f87cd84896d50202b6fa4543

), through a large number of experiments by scientific researchers, it is proved that using a certain low-power motor with a speed amplification under the action of gravity (the internal mechanism is to use the reaction force of the fulcrum of the bearing ) after torque , it can drive a generator with a certain high-power to generate normal power, generating a total electrical energy greater than the electrical energy consumed by a certain low-power motor. This phenomenon does not violate the traditional classical physical energy conservation law . This is because the motor rotor cuts the magnetic inductive line in the space for half-circumferential speed movement when the stator with a conservative gravitational field exists, and is affected by gravity when it is transformed into conservative electromagnetic energy. The total gravitational energy is equal to a part of the gravitational energy plus a part of the electromagnetic energy. Otherwise, the energy cannot be produced out of nothing. To solve the transformation process of electromagnetic energy, in fact, in the process of energy conversion, it is to constantly break the Newtonian static equilibrium and the conservation of energy in statics, and reconstruct the problems of Newtonian dynamic equilibrium and the conservation of energy in motion.All experiments regarding the conversion of electromagnetic energy and gravitational energy, as long as the generator's low-frequency power output power problem is solved, according to the Faraday's electromagnetic induction law and principles, further improved will be developed into a self-sustaining cycle utility model engine.

From the above analysis, the direct utilization of gravitational energy is the goal we always pursue. In this energy conversion process, we can conclude from this: in the bending space-time and space where the conservative gravitational field exists, when the rotating body moves in half-circumferential curves to change the magnetic flux in closed wire , gravitational energy can be converted into conserved electromagnetic energy. Therefore, we only need to consume a part of the limited electromagnetic energy to complete the half-circumferential curve movement opposite to the direction of gravity action, and we can obtain gravitational energy much greater than electromagnetic energy.

Because: A1B1+ B1A1=A2C2=C2A2, 2A1B1=A2C2 or 2B1A1=C2A2, F1 electromagnetic force+F2 gravity=F3=F4 gravity, E1 electromagnetic energy + E2 gravitational energy = E3 electromagnetic energy = E4 gravitational energy

Find the situation of the two wheels repeating motion: A1B1, F1 electromagnetic force, E1 electromagnetic energy

Solution:

1, ∵ A1B1+ B1A1= A2C2=C2A2

∴A1B1= C2A2-B1A1

or A1B1= 1/2C2A2 (Conservation of Angular Momentum)

2, ∵F1 electromagnetic force + F2 gravitational = F3=F4 gravitational

∴ F1 electromagnetic force = F4 gravitational—F2 gravitational

or F1 electromagnetic force = 1/2 F3 = 1/2F4 gravity (according to Newton's fourth law of motion (permanent dynamics law), that is, the "interactive mechanism of two points of action" and its "sum principle of the sum of two forces whose angular kinetic energy combined force is non-zero") [4]

3, ∵ E1 electromagnetic energy + E2 gravitational energy = E3 = E4 gravitational energy

∴E1 electromagnetic energy = E4 gravitational energy - E2 gravitational energy

or E1 electromagnetic energy = 1/2 E4 gravitational energy (conservation of kinetic energy)
