What is a Free Energy Generator : Making and Its Applications

Nikola Tesla (10th July 1856 – 7th January 1943) invented free energy by using a coil. The mechanical energy is converted into electrical energy by generators, the important elements of the generators are the magnetic field and the motion of the conductor in a magnetic field. The free energy generator is a device, which is used to generate electrical energy based on the neodymium magnets principle. There are different types of generators in different sizes, in that free energy generator is one type of generator which generates electrical energy. This article discusses an overview of the free energy generator which includes its definition, advantages, disadvantages and its applications.

What is Free Energy Generator?

Derivation: The free energy generator is one type of device which is used to generate electrical energy and it works on the principle of neodymium magnets. Some of the free energy generator products are Hydro Generator and Hydro Turbine, Pelton Hydro Turbine Generator, Renewable Free Energy Water Wheel, Pelton Turbina Generator 50 Kw Micro Hydropower Turbine, 30Kw 150rpm 400v rpm Permanent Magnet Alternator Free Energy Magnetic Generator, 750kva SDEC Free Energy Diesel Generator, etc.

Flywheel Moment of Inertia Derivation

The flywheels are required to store the energy because the engine produces energy only in one stroke, but it has to complete in 4 strokes one is suction stroke, compression stroke, power stroke or expansion stroke, and exhaust stroke. The power is the only stroke in which we get the energy from the engine and that energy from the power stroke has to be stored somewhere so that it can be utilized to make the other three strokes also. The flywheel stores the energy using its moment of inertia and the flywheel stores the energy in the formula like

E = 1/2 Iω2

Where ‘E’ is the energy

‘I’ is the moment of inertia


‘ω’ is the angular velocity

The moment of inertia can be calculated by

I = 1/2 m (r external2 + r internal 2)

The energy that is stored by the wheel must be greater than the energy that is required for conducting the suction stroke, compression stroke, and exhaust stroke. The energy that is stored by the wheel is less than the energy that is required for conducting the suction stroke, compression stroke, and exhaust stroke then the engine will not work because it might be not able to conduct all other three strokes.

Previously the flywheels are made by cast iron only, but now industries choose different types of materials to make flywheels they are steel, cast iron, aluminum, etc. The flywheel does not maintain a constant speed but only prevents the fluctuation of energy.

If the mass in the above figure goes towards the earth and the potential energy of mass is equal to mgh.

P.E (Potential Energy) = mgh

When the mass decreases the potential energy also decreases and that potential energy is partially divided into three paths.

  • Path 1: Translational Kinetic Energy =1/2 mv2
  • Path 2: Rotational Kinetic Energy =1/2 I ω2
  • Path 3: Work Against Friction = n1 f

The P.E (Potential Energy) is equal to mgh is divided into three paths that are Translational Kinetic Energy, Rotational Kinetic Energy, and Work Against Friction that is expressed as

Mgh=Translational K.E + Rotational K.E+ Work Against Friction …eq(1)

The linear velocity is equal to angular velocity and it is expressed as

V = r*ω…….. eq(2)

When the mass moves towards the downward direction the rotational kinetic energy is used against the frictional energy.

1/2 I ω2 = n2 f

f = I ω2 / 2n2……….. eq(3)

Substitute eq (2) an eq (3) in eq (1) will get

Mgh = 1/2 m r2 ω2 + 1/2 I ω2 + n1 I ω2 / 2n2……….. eq(4)

Multiply the above equation with 2 will get

2 Mgh = m r2 ω2 + I ω2 + I ω2 (1 + n1/ n2)

2 Mgh – m r2 ω2 = I ω2 (1 + n1/ n2)

2 Mgh – m r2 ω2/ ω2 (1 + n1/ n2) = I

I = (2 Mgh- m r2 ω2/ ω2) / (1 + n1/ n2)……….. eq(5)

An average velocity of the flywheel is ω/2

Average velocity = 2Πn / t

Where n becomes n­­­­2

ω/2 = 2Π n­­­­2 / t

ω = 4Π n­­­­2 / t ….. eq(6)

Substitute eq (6) in eq (5) will get

I = (m(2ght2/16 Π2 n­­­­22)-r2) / (1 + n1/ n2)

I = (m(ght2/8 Π2 n­­­­22)-r2) / (1 + n1/ n2)……….. eq(7)

Where height (h) = 2rn1…… eq(8)

Substitute eq (8) in eq (7) will get

Where height (h) = 2rn1……… eq(8)

Substitute eq (8) in eq (7) will get

I = (m(g2Πrn1t2/8 Π2 n­­­­22)-r2) / (1 +n1 / n2

I = mr*((gn1t2/Π n­­­­22)-r)/ (1 + n1/ n2)……….. eq(9)

An equation (9) is the moment of inertia in kg/m2

Flywheel Working

Consider a foot-operated sewing machine consists of two wheels, one big wheel and another one is a smaller wheel. These two wheels are connected by rope when motion is imparted by the bigger wheel then the rope transfers this motion to the smaller wheel. The smaller wheel acts as a pulley and rounds the sewing machine and will see that even when we stop supplying driving force to the bigger wheel, it continues to run for a short time because of the inertia it possesses. That flywheel is a device that acts as an energy reservoir by storing and supplying mechanical energy when required. The figure (a) is flywheel and figure (b) is a basic diagram of free energy generator flywheel are shown below


The flywheel is used in reciprocating engines to store some amount of energy during the power stroke and deliver it back during the next cycle. Similarly, it is used in toy cars, Gyroscopes, etc.

Making of Free Energy using Capacitor

We need some components to make free energy using the capacitor they are 8 capacitors of 10v and 4700uf, PCB (Printed Circuit Board), Soldering Iron, and Soldering wire. First, make a circuit diagram by connecting capacitors in a parallel circuit, all negative side capacitors connected to one wire and all the negative side capacitors connected to another wire like the circuit diagram shown below


Now connect all capacitors to the printed circuit board using a circuit diagram. It is the process to make free energy using a capacitor. Once the process is completed next step is testing, in the testing process first, you have charged the capacitors between 6 to 8 volts and then test the LED or DC motor. If the connections are given correctly the LED will blink and DC motor will run.

Permanent Magnet DC Motor

The PMDC motor that is Permanent Magnet DC Motor consists of two main components they are rotor or armature and stator. Hence the construction of the DC motor is essential to establish a magnetic field. The magnetic can be any type of electric magnet or a permanent magnet. When a permanent magnet is using to create a magnetic field in a DC motor is referred to as Permanent Magnet DC Motor. Here stator permanent magnet mounted in the peripheral of the stator and the permanent magnet mounted in such a way that N pole and S pole of each magnet is alternately faced to each other. The rotor of the permanent magnet motor is similar to other DC motors. The rotor or armature consists of core, winding, and commutator. The Permanent Magnet DC Motor diagram is shown below


The armature core is made up of several of insulated slotted circular lamination of steel sheet, by placing this circular steel one by one armature core has formed. The armature conductor is connected to the rotor in star connection and another terminal of winding is connected to the commutator segment placed on the motor shaft. The carbon or graphite has placed with spring on the commutator segment to supply current to the armature, when supply was given the current passes through commutator segment AB, BC or CA. Suppose the current passes through the CA path, that coil A behaves like a north pole then torque works on a rotor because A experiences a repletion force due to the south pole permanent magnet and the north pole permanent magnet, due to this the rotor will rotate. When input power is consumed DC motor efficiency is improved and this is one of the advantages of permanent magnet DC motor.
