How can Make Free Energy Generator

Before building a free energy generator, we need to understand:

What is a free energy generator?
How many types of free energy generators?
How to build (design) a free energy generator

What is a free energy generator?

You still have to spend money to buy machines and tools to design it. So, you still have to waste it initially. Later, there may be no more costs.
The free energy generator is having a machine that generates electrical energy, then cuts off the contract with the power company. This is the wish of many low and middle income people. For the rich, they seem to have some knowledge to think that there is no free energy generator. The poor must share their fate, by paying money to the electricity company.
It is an understanding of free energy generators that are easy to understand and tend to bring benefits to the poor.
Understand more about free energy generators:

#1. Scientific basis against free energy generators

Science, it is in the human mind. The scientific basis against free energy is the understanding of science in the minds of a group of people (it seems that this group is very large and funded by the electricity industry). So science itself is not against free energy, it is human.
What do they say?
They say:

Free energy is a violation of energy conservation law
Nothing is free. You have to pay as well ...
Where is the energy taken from? Jugglery
and more…

Intuition and universal science can draw intuitive conclusions: Free energy generators are impossible.
Not just ordinary people, but even old and present scientists oppose free energy.

#2. What is the real science for free energy generators?

That is the Ether. But really few understand the Ether, since Einstein's theory of relativity was born, it lost its position in science.
Understanding simple Ether: Ether is an overarching thing throughout the universe that governs electromagnetic waves, gravity, light velocity, energy, etc. Energy "zero points" is a concept that builds the Ether theory.
According to the Ether theory, there is no so-called gravitational force.
Science cannot yet unify the gravitational and electromagnetic forces. According to the Ether doctrine, that unification is not necessary.
This is a quote about "zero point" Energy:

The Unified Field Theory is being searched for by scientists who want to come up with a theory which encompasses the force of gravity with the electromagnetic force. In my opinion, they would have more chance of success in trying to find a needle in a haystack which does not contain a needle since when the entire haystack has been disassembled, it becomes clear that there never was a needle in it. In my opinion, there is no such thing as a “force of gravity”, in fact, there is no such thing as gravity. Find that hard to believe? Well, let me explain.
If when standing, you hold an object a waist level and let it go, it “falls” and lands near your feet. Yes agreed, and yet I suggest that there is no such thing as gravity. If you suspend a pendulum close to a mountain, the pendulum does not hang down vertically but moves slightly towards the mountain. This is said to be because the mountain attracts the pendulum. Sorry Chief, but that just ain’t true - the mountain does not attract the pendulum.
The reason why “the force of gravity” is so tiny compared to electromagnetism is because there is no such force at all. Yes, indeed, all of the observed phenomena which are supposed to be gravitational, do exist exactly as seen, but I suggest that there is no such thing as “the force of gravity” and the Unified Field Theory is not needed. Let me explain:
The Zero-Point Energy field exists everywhere in the universe and it flows in every direction equally. It acts like a flow of particles thousands of times more tiny than electrons, and so, it flows through matter. No matter can shield completely from the flow of this energy field. But, a tiny percentage of the flow does happen to collide with the electrons, atoms and molecules of matter as the energy flow moves through matter. The bigger the chunk of matter, the more of the energy flow collides with it. The collisions convert the energy into additional mass, which is why our Sun is not losing mass as rapidly as theory would predict. The situation is like this:

The force of the Zero-Point Energy field is slightly reduced having passed through (and interacted with) the large mass of the Earth. This reduced strength in indicated in the diagram by the light-blue arrows. The incoming Zero-Point Energy field is not reduced in strength in any significant way as the molecules in the atmosphere are not nearly as tightly packed as those in the matter which makes up the Earth itself. The imbalance of these two thrusts causes a net push towards the surface of the Earth.
For clarity, the diagram only shows the field acting in one direction, while in reality, the same situation applies in every possible direction around the planet. When you let an object go and it moves towards the surface of the planet, it is not being pulled down by “the force of gravity”, but instead, the downward push of the Zero-Point Energy field is greater than the upward push of the Zero-Point Energy field which has just passed through the planet. The object moves “downwards” because the push from above is greater than the push from below.
Exactly the same thing applies to cause the effect that a mountain appears to have on a pendulum. In reality, the mountain has no effect on the pendulum, apart perhaps from a minor electrostatic influence. The main effect is caused by the flow of the Zero-Point Energy field:

Here, the (very roughly drawn) mountain, reduces the push of the Zero-Point Energy field which passes through it, due to its interaction with the matter with which it collides on its trip through the mountain. The push of the Zero-Point Energy field on the side of the pendulum is not diminished, so there is a net push towards the mountain and that makes the pendulum move in the direction of the mountain. The effect is not very large, so the pendulum does not move much out of the vertical as the downward push towards the surface of the planet is quite marked, so the pendulum needs to be very near the mountain for this effect to be observed.
This can also be seen in the Casimir Effect where two non-magnetic metal plates, which are not carrying an electrostatic charge, are suspended very close to each other. The plates do not hang straight down but move towards each other. This is the same effect as is caused by a mountain near a stationary pendulum, or plumb-line. Each plate screens out a little of the Zero-Point Energy field which passes directly through both plates, so the second plate gets slightly less of a push:

The result is that between the plates, the horizontal force pushing them is unbalanced. Hang just one plate up and the horizontal Zero-Point Energy (“ZPE”) forces coming from the right exactly balance the ZPE forces coming from the left, and the plate hangs vertically below its point of suspension with the supporting cord (shown in red in the diagram above) hangs vertically. But with two plates as shown, the push from the left is reduced very slightly as it passes through the left hand metal plate. This means that there is a lesser push from left to right on the right hand plate. This causes the plate to move very slightly to the left, until the horizontal pull caused by the red cord not being vertical, just balances the difference in the ZPE thrusts on that plate. So, the right hand plate moves slightly to the left.
The same thing happens with the left hand plate. The ZPE thrust coming from the right is slightly reduced as it passes through the right hand plate, and the left hand plate moves slightly to the right until the angled pull of its supporting cord balances the net thrust on that plate. The overall effect is that the gap at point “A” in the diagram is very slightly larger than the gap at point “B”, though the amount is not nearly as great as suggested by the diagram, which has been deliberately exaggerated to show the effect clearly. There is nothing complicated about this, it is just simple common sense. Remember that the pull of the supporting cord “ C ” is the exact equivalent of a vertical force “ D” along with a horizontal force “ E ”. Here, the vertical force D exactly matches the weight of the plate, and the horizontal force E
exactly matches the unbalanced ZPE force (if they did not match exactly, then the plate would move until they did). The further away from the vertical that the plate moves, the greater the resulting horizontal force caused by the pull of the supporting cord.
Tesla expressed this in a very slightly different way in his Dynamic Theory of Gravity (1897) which states that all bodies emit microwaves whose voltage and frequency are determined by their electrical contents and relative motion. He measured the microwave radiation of the earth as being only a few centimetres in wavelength. He said that the frequency and voltage were influenced by the velocity and mass of the earth, and that its “gravitational” interaction with other bodies, such as the sun, was determined by the interaction of the microwaves between the two bodies.
If you find the concept of producing a driving force through pushing against the space-time continuum to be difficult to accept, then perhaps you should consider the US Patent granted to Boris Volfson on 1st November 2005. The important thing about this patent (which is crammed full of long words) is not whether or not it presents a realistic mechanism for a practical space drive, but the fact that the US Patent Office in the year 2005, granted the patent after what presumably was careful consideration. With that in view, it is hardly possible to consider Tesla to have been totally confused when he designed (and built) his “electric flying machine” which operated by pulling on the space-time field.
Tesla used high voltage at gigahertz frequencies for his electropulsion system. The propulsion of a vehicle powered by a Tesla drive is by the use of an additional AC generator at the back (which stiffens the space-time continuum behind the vehicle) and a DC ‘brush’ generator at the front (which weakens the space-time continuum in front, causing the vehicle to be pulled forwards).
Tesla was very astute. He deduced that ‘empty space’ actually contained:

Independent carriers which permeate all space and all matter and from which all matter is made. These carry momentum, magnetism, electricity or electromagnetic force, and can be manipulated artificially or by nature.

‘Primary Solar Rays’ (starlight) which travel at the speed of light, having frequencies far above X-rays, gamma and UV radiation.

‘Cosmic Rays’, particles in space propelled by the Primary Solar Rays.

X-rays, Gamma rays and UV electromagnetic waves, all of which travel at the speed of light.

Ordinary visible and Infra-Red electromagnetic waves which travel at the speed of light.

Rapidly varying electrostatic force of enormous potential, emanating from the earth and other gravitational bodies in space.

When we grasp the actual nature of the universe, it becomes clear that we have a much larger range of opportunities for producing usable energy in large quantities and at minimal cost.
Additional information can be found in Boris Volfson’s US Patent 6,960,975 of November 2005 “Space Vehicle Propelled by the Pressure of Inflationary Vacuum State” which is reproduced in the Appendix.
If you find the thought of generating a gravitational field, difficult to come to terms with, then consider the work of Henry Wallace who was an engineer at General Electric about 25 years ago, and who developed some incredible inventions relating to the underlying physics of the gravitational field. Few people have heard of him or his work. Wallace discovered that a force field, similar or related to the gravitational field, results from the interaction of relatively moving masses. He built machines which demonstrated that this field could be generated by spinning masses of elemental material having an odd number of nucleons -- i.e. a nucleus having a multiple half-integral value of h-bar, the quantum of angular momentum. Wallace used bismuth or copper material for his rotating bodies and "kinnemassic" field concentrators.
Aside from the immense benefits to humanity which could result from a better understanding of the physical nature of gravity, and other fundamental forces, Wallace's inventions could have enormous practical value in countering gravity or converting gravitational force fields into energy for doing useful work. So, why has no one heard of him? One might think that the discoverer of important knowledge such as this would be heralded as a great scientist and nominated for dynamite prizes. Could it be that his invention does not work? Anyone can get the patents. Study them -- Wallace -- General Electric -- detailed descriptions of operations -- measurements of effects -- drawings and models -- it is authentic. If you are handy with tools, then you can even build it yourself. It does work.

Nikola Tesla deeply understands about Ether. He wants to build a free energy generator around the world. So his generator model will be different from other free power generators. This is the difference between large scale and small scale.
The question is: Has Tesla finished his invention?
If the answer is YES!
At this time, the electricity industry must stop.
Nikola Tesla completed his invention while being watched by the FBI. He did not publish his invention (even buried it). Because, in addition to the positive side of free energy generators, it also has a negative side. People will be lazy when having this generator, greed and anger, along with free energy, will probably destroy humanity (This is just a hypothesis for reference)
Back to the free power generator:
Tesla's generators provide the whole world, with a special self-maintenance mechanism designed specifically for:

How many types of free energy generators?

Still based on Tesla's "zero-point" power and Tesla's original and later ideas for free power generators, scientists have evolved into a wide variety of different generators.
The goal is not for the whole world, but on a small scale. Here are a few examples:
A Three Battery Switching System - Free Energy Generator
Energy-Tapping Pulsed Systems - Free Energy Generator
Solves Tesla's Secret to Amplifying Power by Nearly 5000% - Groundbreaking Discovery
In addition, the magnetic motor - self-sustaining, is also the development of Tesla's work. Watch this video to know:

How to build (design) a free energy generator

Three important things before building a free energy generator

Choose the style of generator suitable for each individual
Find documentation for selected generator types
Have a little knowledge of electrical engineering

Which one should you choose?
In my opinion, you should choose the type of machine that amplifies "Electron oscillator signal" by Motionless Pulsed Systems. Its nature is still the way to get energy from Nikola Tesla's Ether - energy from the earth. Furthermore, it is very efficient and has no annoying rotary engine.
