How to generate electricity from a magnet. Obtaining electrical energy from the magnetic field of permanent magnets. Free energy, alternative energy

Exists a large number of devices belonging to the so-called "". Among them, there are numerous designs of current generators that make it possible to obtain electricity from a magnet. These devices use the properties of permanent magnets capable of performing external useful work.

Currently, work is underway to create a device capable of driving a device that generates current. Research in this area has not yet been fully completed, however, based on the results obtained, one can fully imagine its structure and principle of operation.

How to get electricity from a magnet

In order to understand how such devices work, you need to know exactly how they differ from conventional electric motors. All electric motors, although they use the magnetic properties of materials, move solely under the influence of current.

To operate a real magnetic motor, only the constant energy of magnets is used, with the help of which all the necessary movements are performed. The main problem with these devices is the tendency of the magnets to become statically balanced. Therefore, the creation of variable attraction, using physical properties magnets or mechanical devices in the motor itself.

The operating principle of a permanent magnet motor is based on the torque of repulsive forces. The action of the same magnetic fields of permanent magnets located in the stator and rotor occurs. Their movement is carried out in the opposite direction in relation to each other. In order to solve the problem of attraction was used copper conductor with an electric current passed through it. Such a conductor begins to be attracted to the magnet, but in the absence of current, the attraction stops. As a result, a cyclic attraction and repulsion of the stator and rotor parts is ensured.

Main types of magnetic motors

Over the entire period of research, a large number of devices have been developed that make it possible to obtain electricity from a magnet. Each of them has its own technology, but all models are united. Among them there are no ideal perpetual motion machines, since magnets completely lose their qualities after a certain time.

The simplest device is the anti-gravity magnetic Lorentz engine. Its design includes two disks with opposite charges connected to power. Half of these disks are placed in a hemispherical magnetic screen, after which they begin to gradually rotate.

The most realistic functioning device is considered to be the simplest design of the Lazarev rotary ring. It consists of a container that is divided in half by a special porous partition or ceramic disk. A tube is installed inside the disk, and the container itself is filled with liquid. First, the liquid enters the bottom of the container, and then, under the influence of pressure, the sweat tube begins to move upward. Here the liquid begins to drip from the curved end of the tube and again enters the lower part of the container. In order for this structure to take the form of an engine, a wheel with blades is located under the drops of liquid.

Magnets are installed directly on the blades, generating a magnetic field. The rotation of the wheel accelerates, water is pumped faster and, in the end, a certain maximum operating speed of the entire device is established.

The basis of the Shkondin linear motor is the system of placing one wheel in another wheel. The entire structure consists of a double pair of coils with opposite magnetic fields. This ensures their movement in different directions.

The alternative Perendeva engine uses only magnetic energy. The design consists of two circles - dynamic and static. Magnets are located on each of them in the same sequence and intervals. The free force of self-repulsion sets the inner circle into endless motion.

Application of permanent magnet devices

The results of research in this area are already making us think about the prospects for using magnetic devices.

In the future, there will be no need for all kinds of chargers. Instead they will be used magnetic motors the most different sizes, driving miniature current generators. Thus, many laptops, tablets, smartphones and other similar equipment will work continuously for a long time. These power supplies will be able to be switched from old models to new ones.

Magnetic devices with higher power will be able to rotate such generators, which will replace the equipment of modern power plants. They can easily work instead of internal combustion engines. Each apartment or house will have an individual energy supply system.

Universal use of electricity in all areas human activity associated with the search for free electricity. Because of this, a new milestone in the development of electrical engineering was an attempt to create a free energy generator that would significantly reduce the cost or reduce to zero the cost of generating electricity. The most promising source for realizing this task is free energy.

What is free energy?

The term free energy arose during the time of large-scale introduction and operation of internal combustion engines, when the problem of obtaining electric current directly depended on the coal, wood or petroleum products used for this. Therefore, free energy is understood as a force for the production of which there is no need to burn fuel and, accordingly, consume any resources.

The first attempts to scientifically substantiate the possibility of obtaining free energy were laid by Helmholtz, Gibbs and Tesla. The first of them developed the theory of creating a system in which the generated electricity should be equal to or greater than that spent for the initial start-up, that is, obtaining a perpetual motion machine. Gibbs expressed the possibility of obtaining energy by flowing chemical reaction so long that it is enough for a full power supply. Tesla observed energy in all natural phenomena and proposed a theory about the presence of ether, a substance that permeates everything around us.

Today you can observe the implementation of these principles to obtain free energy in. Some of them have long ago entered the service of humanity and help to receive alternative energy from wind, sun, rivers, tides. These are the same solar panels, hydroelectric dams that helped harness the forces of nature that were freely available. But along with already proven and implemented free energy generators, there are concepts of fuel-free engines that try to circumvent the law of conservation of energy.

The problem of energy conservation

The main stumbling block in obtaining free electricity is the law of conservation of energy. Due to the presence of electrical resistance in the generator itself, connecting wires and other elements electrical network, according to the laws of physics, there is a loss of output power. Energy is consumed and to replenish it, constant external replenishment is required or the generation system must create such an excess electrical energy, so that it is enough to both power the load and maintain the operation of the generator. From a mathematical point of view, the free energy generator must have an efficiency greater than 1, which does not fit into the framework of standard physical phenomena.

Circuit and design of the Tesla generator

Nikola Tesla became the discoverer of physical phenomena and based on them created many electrical devices, for example, Tesla transformers, which are used by humanity to this day. Over the entire history of his activities, he has patented thousands of inventions, among which there is more than one free energy generator.

Rice. 1: Tesla Free Energy Generator

Look at Figure 1, this shows the principle of generating electricity using a free energy generator made from Tesla coils. This device involves obtaining energy from the ether, for which the coils included in its composition are adjusted to resonant frequency. To obtain energy from the surrounding space in this system, the following geometric relationships must be observed:

• winding diameter;
• wire cross-section for each winding;
• distance between coils.

Known today various options the use of Tesla coils in the design of other free energy generators. True, it has not yet been possible to achieve any significant results from their use. Although some inventors claim the opposite, and keep the results of their developments in the strictest confidence, demonstrating only the final effect of the generator. In addition to this model, other inventions of Nikola Tesla are known, which are generators of free energy.

Magnetic free energy generator

Interaction effect magnetic field and coils are widely used in . And in a free energy generator, this principle is used not to rotate a magnetized shaft by applying electrical impulses to the windings, but to supply a magnetic field to an electric coil.

The impetus for the development of this direction was the effect obtained by applying voltage to an electromagnet (a coil wound on a magnetic circuit). In this case, a nearby permanent magnet is attracted to the ends of the magnetic circuit and remains attracted even after turning off the power from the coil. A permanent magnet creates a constant flow of magnetic field in the core, which will hold the structure until it is torn off by physical force. This effect was used to create a permanent magnet free energy generator circuit.

Look at Figure 2, to create such a free energy generator and power the load from it, it is necessary to form a system of electromagnetic interaction, which consists of:

• trigger coil (I);
• locking coil (IV);
• supply coil (II);
• support coil (III).

The circuit also includes a control transistor VT, a capacitor C, diodes VD, a limiting resistor R and a load Z H.

This free energy generator is turned on by pressing the “Start” button, after which the control pulse is supplied through VD6 and R6 to the base of transistor VT1. When a control pulse arrives, the transistor opens and closes the current flow circuit through the starting coils I. After which electricity will flow through the coils I and excite a magnetic circuit, which will attract a permanent magnet. Magnetic field lines will flow along the closed contour of the magnet core and permanent magnet.

An emf is induced from the flowing magnetic flux in coils II, III, IV. The electrical potential from the IV coil is supplied to the base of the transistor VT1, creating a control signal. The EMF in coil III is designed to maintain the magnetic flux in the magnetic circuits. The EMF in coil II provides power to the load.

The stumbling block in the practical implementation of such a free energy generator is the creation of an alternating magnetic flux. To do this, it is recommended to install two circuits with permanent magnets in the circuit, in which the power lines are in the opposite direction.

In addition to the above free energy generator using magnets, today there are a number of similar devices designed by Searle, Adams and other developers, the generation of which is based on the use of a constant magnetic field.

Followers of Nikola Tesla and their generators

The seeds of incredible inventions sown by Tesla gave birth to an insatiable thirst in the minds of applicants to turn into reality fantastic ideas for creating a perpetual motion machine and send mechanical generators to the dusty shelf of history. The most famous inventors used the principles laid down by Nikola Tesla in their devices. Let's look at the most popular of them.

Lester Hendershot

Hendershot developed a theory about the possibility of using the Earth's magnetic field to generate electricity. Lester presented the first models back in the 1930s, but they were never in demand by his contemporaries. Structurally, the Hendershot generator consists of two counter-wound coils, two transformers, capacitors and a movable solenoid.

The operation of such a free energy generator is only possible if it is strictly oriented from north to south, so a compass must be used to set up the operation. The coils are wound on wooden bases with multidirectional winding to reduce the effect of mutual induction (when EMF is induced in them, EMF will not be induced in the opposite direction). In addition, the coils must be tuned by a resonant circuit.

John Bedini

Bedini introduced his free energy generator in 1984; a feature of the patented device was an energizer - a device with a constant rotating torque that does not lose speed. This effect was achieved by installing several permanent magnets on the disk, which, when interacting with an electromagnetic coil, create impulses in it and are repelled from the ferromagnetic base. Due to this, the free energy generator received a self-powering effect.

Bedini's later generators became known through a school experiment. The model turned out to be much simpler and did not represent anything grandiose, but it was able to serve as a generator free electricity about 9 days without outside help.

Look at Figure 4, here is a schematic diagram of the free energy generator of that same school project. It uses the following elements:

• a rotating disk with several permanent magnets (energizer);
• coil with a ferromagnetic base and two windings;
• battery (in in this example it was replaced with a 9V battery);
• control unit consisting of a transistor (T), resistor (P) and diode (D);
• Current collection is organized from an additional coil that powers the LED, but power can also be supplied from the battery circuit.

With the start of rotation, the permanent magnets create magnetic excitation in the coil core, which induces an emf in the windings of the output coils. Due to the direction of the turns in the starting winding, current begins to flow, as shown in the figure below through starting winding, resistor and diode.

When the magnet is located directly above the solenoid, the core is saturated and the stored energy becomes sufficient to open the transistor T. When the transistor opens, current begins to flow in the working winding, which recharges the battery.

At this stage, the energy becomes sufficient to magnetize the ferromagnetic core from the working winding, and it receives a pole of the same name with a magnet located above it. Thanks to the magnetic pole in the core, the magnet on the rotating wheel is repelled from this pole and accelerates the further movement of the energizer. As the movement accelerates, pulses appear in the windings more often, and the LED switches from flashing mode to constant glow mode.

Alas, such a free energy generator is not a perpetual motion machine; in practice, it allowed the system to work tens of times longer than it could function on a single battery, but eventually it still stops.

Tariel Kapanadze

Kapanadze developed a model of his free energy generator in the 80s and 90s of the last century. Mechanical device based on the operation of an improved Tesla coil, as the author himself claimed, the compact generator could power consumers with a power of 5 kW. In the 2000s, Kapanadze's generator industrial scale they tried to build 100 kW in Turkey, according to technical specifications it required only 2 kW to start and operate.

The figure above shows a schematic diagram of a free energy generator, but the main parameters of the circuit remain a trade secret.

Practical circuits of free energy generators

Despite the large number of existing schemes for free energy generators, very few of them can boast of real results that could be tested and repeated at home.

Figure 8 above shows a free energy generator circuit that you can replicate at home. This principle was outlined by Nikola Tesla; it uses a metal plate isolated from the ground and located on some hill. The plate is a receiver of electromagnetic oscillations in the atmosphere, this includes a fairly wide range of radiation (solar, radiomagnetic waves, static electricity from the movement of air masses, etc.)

The receiver is connected to one of the plates of the capacitor, and the second plate is grounded, which creates the required potential difference. The only stumbling block to its industrial implementation is the need to isolate a large plate on a hill to power even a private home.

Modern look and new developments

Despite widespread interest in creating a free energy generator, it has been forced out of the market classic way They are not yet able to obtain electricity. Developers of the past, who put forward bold theories about significantly reducing the cost of electricity, lacked the technical perfection of the equipment or the parameters of the elements could not provide the desired effect. And thanks to scientific and technological progress, humanity is receiving more and more inventions that make the embodiment of a free energy generator already tangible. It should be noted that today free energy generators powered by the sun and wind have already been obtained and are actively being used.

But, at the same time, on the Internet you can find offers to purchase such devices, although most of them are dummies created with the aim of deceiving an ignorant person. And a small percentage of actually operating free energy generators, whether on resonant transformers, coils or permanent magnets, can only cope with powering low-power consumers, providing electricity, for example, a private house or lighting in the yard they can't. Free energy generators – promising direction, but their practical implementation still not implemented.

Energy from a permanent magnet's field

Many people are trying to implement the idea contained in the device described below. Its essence is this: there is a permanent magnet (PM) - a hypothetical source of energy, an output coil (collector) and a certain modulator that changes the distribution magnetic field of a permanent magnet, thereby creating a variable magnetic flux in the coil.

Implementation (18.08.2004)

To implement this project (let's call it TEG, as a derivative of two designs: VTA by Floyd Sweet and MEG by Tom Burden :)) I took two ferrite ring core brand M2000NM with dimensions O40xO25x11 mm, put them together, fastening them with electrical tape, and wound the collector (output) winding around the perimeter of the core - 105 turns with PEV-1 wire in 6 layers, also securing each layer with electrical tape.

Next, we wrap it again with electrical tape and wind the modulator coil (input) on top. We wind it as usual - toroidal. I wound 400 turns into two PEV-0.3 wires, i.e. It turned out two windings of 400 turns. This was done in order to expand the experimental options.

Now we place this entire system between two magnets. In my case, these were barium oxide magnets, material grade M22RA220-1, magnetized in a magnetic field of at least 640,000 A/m, dimensions 80x60x16 mm. The magnets are taken from a magnetic-discharge diode pump NMD 0.16-1 or similar. The magnets are oriented “at attraction” and their magnetic lines penetrate the ferrite rings along the axis.

TEG assembly (diagram).

The work of the TEG is as follows. Initially, the magnetic field strength inside the collector coil is higher than outside due to the presence of ferrite inside. If the core is saturated, its magnetic permeability will sharply decrease, which will lead to a decrease in the voltage inside the collector coil. Those. we need to create such a current in the modulating coil to saturate the core. By the time the core is saturated, the voltage on the collector coil will increase. When the voltage is removed from the control coil, the field strength will increase again, which will lead to a surge of reverse polarity at the output. The idea as presented was born somewhere in mid-February 2004.

In principle, one modulation coil is sufficient. The control unit is assembled according to the classical scheme on TL494. The upper variable resistor in the diagram changes the duty cycle of the pulses from 0 to approximately 45% on each channel, the lower one sets the frequency in the range from approximately 150 Hz to 20 kHz. When using one channel, the frequency is correspondingly reduced by half. The circuit also provides current protection through the modulator of approximately 5A.

TEG assembly (appearance).

TEG parameters (measured with a MY-81 multimeter):

winding resistance:
collector - 0.5 Ohm
modulators - 11.3 Ohm and 11.4 Ohm

collector - 1.16 mH
modulators - 628 mH and 627 mH

collector - 1.15 mH
modulators - 375 mH and 374 mH

Experiment No. 1 (08/19/2004)

The modulator coils are connected in series, so it looks like a bifilar. One generator channel was used. The modulator inductance is 1.52 H, resistance is 22.7 Ohm. The power supply of the control unit here and below is 15 V, the oscillograms were taken with a two-beam oscilloscope S1-55. The first channel (lower beam) is connected through a 1:20 divider (Cin 17 pF, Rin 1 Mohm), the second channel (upper beam) is connected directly (Cin 40 pF, Rin 1 Mohm). There is no load in the collector circuit.

The first thing that was noticed was: after removing the pulse from the control coil, resonant oscillations arise in it, and if the next pulse is applied at the moment of antiphase to the resonant burst, then at that moment a pulse appears at the output of the collector. This phenomenon was also noticed without magnets, but to a much lesser extent. That is, let’s say, in this case the steepness of the potential change on the winding is important. The amplitude of the output pulses could reach 20 V. However, the current of such surges is very small, and it is difficult to charge a 100 µF capacitor connected to the output through a rectifier bridge. The output does not carry any other load. At a high frequency of the generator, when the modulator current is extremely small, and the shape of the voltage pulses on it remains rectangular shape, emissions at the output are also present, although the magnetic circuit is still very far from saturation.

So far nothing significant has happened. Let's just note some effects. :)

Here, I think it would be fair to note that there is at least one more person - a certain Sergei A, experimenting with the same system. His description was in passing www.skif.biz/phpBB2/viewtopic.php?t=48&postdays=0&postorder=asc&start=15. I swear, we came to this idea completely independently :). I don’t know how far his research went; I haven’t contacted him. But he also noted similar effects.

Experiment No. 2 (08/19/2004)

The modulation coils are disconnected and connected to two channels of the generator, and connected in opposite directions, i.e. a magnetic flux is alternately created in the ring in different directions. The inductances of the coils are given above in the TEG parameters. The measurements were carried out as in the previous experiment. There is no load on the collector.

The oscillograms below show the voltage on one of the modulator windings and the current through the modulator (left), as well as the voltage on the modulator winding and the voltage at the collector output (right) at different pulse durations. I won’t indicate the amplitudes and time characteristics for now, firstly, I haven’t saved all of them, and secondly, this is not important for now, as long as we try to qualitatively track the behavior of the system.

The first series of oscillograms shows that at a certain modulator current, the voltage at the collector output reaches a maximum - this is the intermediate moment before the core goes into saturation, its magnetic permeability begins to fall. At this moment, the modulator is turned off and the magnetic field is restored in the collector coil, which is accompanied by a negative surge at the output. In the next series of oscillograms, the pulse duration is increased, and the core reaches complete saturation - the change in magnetic flux stops and the output voltage is zero (decline in the positive region). This is followed again by a reverse surge when the modulator winding is turned off.

Now we will try to exclude magnets from the system while maintaining the operating mode.

When one magnet was removed, the output amplitude decreased by almost 2 times. We also note that the oscillation frequency has decreased since the inductance of the modulators has increased. When the second magnet is removed, there is no output signal.

It seems that the idea, as it was conceived, is working.

Experiment No. 3 (08/19/2004)

The modulator coils are again connected in series, as in the 1st experiment. A back-to-back serial connection has absolutely no effect. I didn't expect anything else :). Connected as expected. Operation is checked both in idle mode and with load. The oscillograms below show the modulator current (upper beam) and output voltage (lower beam) at different pulse durations on the modulator. Here and further, I decided to refer to the modulator current as the most suitable one as a reference signal. The oscillograms were taken relative to the common wire. The first 3 pictures are in idle mode, the last one is with load.

Load power measurements were not carried out, but something else is interesting:

I don’t know what to think... Consumption decreased by 0.3%. The generator itself without TEG consumes 18.5 mA. It is possible that the load indirectly affected the inductance of the modulators through a change in the magnetic field distribution. Although, if you compare the oscillograms of the current through the modulator in idle mode and with a load (for example, when scrolling back and forth in ACDSee), you can notice a slight roll off of the top of the peak when operating with a load. An increase in inductance would lead to a decrease in the peak width. Although all this is very illusory...

Experiment No. 4 (08/20/2004)

The goal is set: to get the maximum output from what we have. In the previous experiment, I came up against the frequency limit at which the optimal pulse duration was ensured at the maximum possible pulse fill level of ~45% (the duty cycle is minimal). So it was necessary to reduce the inductance of the modulator winding (previously two were connected in series), but in this case the current would have to be increased. So now the modulator coils are connected separately to both outputs of the generator, as in the 2nd experiment, but this time they are turned on in the same direction (as indicated in schematic diagram generator). At the same time, the oscillograms changed (they were taken relative to the common wire). They look much nicer :). In addition, we now have two windings that operate alternately. This means that with the same maximum pulse duration we can double the frequency (for this circuit).

A certain operating mode of the generator is selected based on the maximum brightness of the lamp at the output. So, as usual, let's get straight to the drawings...

Here on the left we clearly see an increase in the voltage on the modulator winding during the period of operation of the second one (the second half-cycle, logical “0” on the right oscillogram). Emissions when the 60 volt modulator is turned off are limited by the diodes included in the field switches.

The load is the same lamp 6.3 V, 0.22 A. And again the picture with consumption repeats...

Again we have a decrease in consumption when a load is connected to the collector. The measurements are of course at the threshold of the instrument’s accuracy, but, nevertheless, the repeatability is 100%. The load power was about 156 mW. At the input - 9.15 W. And no one has talked about “perpetual motion” yet :)

Here you can admire the burning light bulb:

Conclusions:

The effect is obvious. What we can get from this - time will tell. What should you pay attention to? First, increase the number of turns of the collector, perhaps by adding a couple more rings, but it would be better to choose optimal sizes magnetic circuit. Who would do the calculations? ;) Perhaps it makes sense to increase the magnetic permeability of the magnetic conductor. This should increase the difference in magnetic field strengths inside and outside the coil. At the same time, the inductance of the modulator would be reduced. It was also thought that gaps were needed between the ring and the magnet so that, let’s say, there was room for bending of the magnetic lines when the properties of the medium—magnetic permeability—changed. However, in practice this only leads to a drop in the output voltage. At the moment, the gaps are determined by 3 layers of electrical tape and the thickness of the modulator winding, by eye this is a maximum of 1.5 mm on each side.

Experiment No. 4.1 (08/21/2004)

Previous experiments were carried out at work. I brought the control unit and the “transformer” home. I had the same set of magnets lying around at home for a long time. Collected. I was surprised to find that I could raise the frequency even more. Apparently my “home” magnets were a little stronger, as a result of which the inductance of the modulators decreased. The radiators were already heating up more, but the current consumption of the circuit was 0.56 A and 0.55 A without load and with load, respectively, with the same power supply of 15 V. It is possible that there was a through current through the switches. In this circuit at high frequencies this is not excluded. I connected a 2.5 V, 0.3 A halogen light bulb to the output. The load received 1.3 V, 200 mA. Total input 8.25 W, output 0.26 W - efficiency 3.15%. But note, again without the expected traditional influence on the source!

Experiment No. 5 (08/26/2004)

A new converter (version 1.2) was assembled on a ring with greater permeability - M10000NM, the dimensions are the same: O40xO25x11 mm. Unfortunately, there was only one ring. To fit more turns on the collector winding, the wire is thinner. Total: a collector of 160 turns with O 0.3 wire and also two modulators of 235 turns, also with O 0.3 wire. A new power supply has also been found up to 100 V and a current of up to 1.2 A. The supply voltage can also play a role, since it provides the rate of increase of the current through the modulator, and that, in turn, the rate of change of the magnetic flux, which is directly related with the amplitude of the output voltage.

There is currently nothing to measure inductance and capture pictures with. Therefore, without further ado, I will present the bare numbers. Several measurements were carried out at different voltages power supply and operating modes of the generator. Below are some of them.

without reaching full saturation

Input: 20V x 0.3A = 6W
Efficiency: 3.6%

Input: 10V x 0.6A = 6W
Output: 9V x 24mA = 0.216W
Efficiency: 3.6%

Input: 15V x 0.5A = 7.5W
Output: 11V x 29mA = 0.32W
Efficiency: 4.2%

with full saturation

Input: 15V x 1.2A = 18W
Output: 16V x 35mA = 0.56W
Efficiency: 3.1%

It turned out that in the full saturation mode, the efficiency decreases, since the modulator current sharply increases. The optimal operating mode (in terms of efficiency) was achieved with a supply voltage of 15 V. No influence of the load on the power source was detected. For the given 3rd example with an efficiency of 4.2, the current of the circuit connected to the load should increase by about 20 mA, but no increase was recorded either.

Experiment No. 6 (2.09.2004)

Some of the modulator turns have been removed in order to increase the frequency and reduce the gaps between the ring and the magnet. Now we have two modulator windings of 118 turns, wound in one layer. The collector is left unchanged - 160 turns. In addition, measured electrical characteristics new converter.

TEG parameters (version 1.21), measured with a MY-81 multimeter:

winding resistance:
collector - 8.9 Ohm
modulators - 1.5 Ohm each

inductance of windings without magnets:
collector - 3.37 mH
modulators - 133.4 mH each
series connected modulators - 514 mH

inductance of windings with installed magnets:
collector - 3.36 mH
modulators - 89.3 mH each
series connected modulators - 357 mH

Below I present the results of two measurements of TEG operation in different modes. With more high voltage power supply modulation frequency is higher. In both cases, the modulators are connected in series.

Input: 15V x 0.55A = 8.25W
Output: 1.88V x 123mA = 0.231W
Efficiency: 2.8%

Input: 19.4V x 0.81A = 15.714W
Output: 3.35V x 176mA = 0.59W
Efficiency: 3.75%

The first and saddest thing. After making changes to the modulator, an increase in consumption was recorded when working with the new converter. In the second case, the consumption increased by about 30 mA. Those. without load the consumption was 0.78 A, with load - 0.81 A. Multiply by the supply 19.4 V and we get 0.582 W - the same power that was removed from the output. However, I will repeat with all responsibility that this has not been observed before. When a load is connected in this case, a steeper increase in current through the modulator is clearly visible, which is a consequence of a decrease in the inductance of the modulator. What this is connected with is not yet known.

And another fly in the ointment. I'm afraid that in this configuration it will not be possible to obtain an efficiency of more than 5% due to the weak overlap of the magnetic field. In other words, by saturating the core, we weaken the field inside the collector coil only in the area of ​​passage of this very core. But the magnetic lines coming from the center of the magnet through the center of the coil are not blocked by anything. Moreover, part of the magnetic lines “displaced” from the core when it is saturated also bypasses the latter from the inside of the ring. Those. In this way, only a small part of the magnetic flux of the PM is modulated. It is necessary to change the geometry of the entire system. Perhaps we should expect some efficiency gains by using ring magnets from speakers. The thought of operating modulators in resonance mode also haunts me. However, under conditions of core saturation and, accordingly, the constantly changing inductance of the modulators, this is not easy to do.

Research continues...

If you want to discuss, go to the "passionate forum" - my nickname Armer. Or write to [email protected], but I think it’s better to go to the forum.

X x x

Dragons" Lord: Firstly, many thanks to Armer for providing a report on the experiments carried out with magnificent illustrations. I think new works by Vladislav await us soon. In the meantime, I will express my thoughts on this project and its possible ways of improvement. I propose changing the generator circuit in the following way:

Instead of flat external magnets (plates), it is proposed to use ring magnets. Moreover, the inner diameter of the magnet should be approximately equal to the similar diameter of the magnetic core ring, and the outer diameter of the magnet should be larger than the outer diameter of the magnetic core ring. What is the problem with low efficiency? The problem is that the magnetic lines displaced from the magnetic circuit still cross the area of ​​the turns of the secondary winding (they are pressed out and concentrated in the central area). The specified ratio of rings creates asymmetry and forces most magnetic lines, with the central magnetic circuit saturated to the limit, go around it in the EXTERNAL space. In the inner region there will be fewer magnetic lines than in the basic version. In fact, this “disease” cannot be completely cured by continuing to use rings. How to increase the overall efficiency is described below.

It is also proposed to use an additional external magnetic circuit, which concentrates the power lines in the working area of ​​the device, making it more powerful (here it is important not to overdo it, since we are using the idea of ​​complete saturation of the central core). Structurally, the external magnetic circuit consists of turned ferromagnetic parts of axisymmetric geometry (something like a pipe with flanges). You can see the horizontal parting line of the upper and lower “cups” in the picture. Or, it can be discrete independent magnetic circuits (brackets).

Next, it is worth considering improving the process from an “electrical” point of view. It’s clear - the first thing to do is to swing the primary circuit into resonance. After all, we have no harmful feedback from the secondary circuit. It is proposed to use CURRENT resonance for obvious reasons (after all, the goal is to saturate the core). The second remark is perhaps not so obvious at first glance. It is proposed to use not a standard solenoid coil winding as a secondary winding, but to make several flat ones bifilar coils Tesla and place them on the outer diameter of the magnetic circuit in a “puff pie”, connecting them in series. In order to completely remove the existing minimal interaction with each other in the axial direction of neighboring bifilar coils, you need to connect them the same way ACROSS ONE, returning from the last to the second ( reuse meaning of bifilar).

Thus, due to the maximum potential difference in two adjacent turns, the stored energy of the secondary circuit will be the maximum possible, which is an order of magnitude greater than the option with a conventional solenoid. As can be seen from the diagram, in view of the fact that the “pie” of bifilars has a fairly decent extent in the horizontal direction, it is proposed to wind the primary not on top of the secondary, but under it. Directly to the magnetic circuit.

As I said, using rings, it is impossible to exceed a certain efficiency limit. And I assure you that there is no smell of over-singularity there. The magnetic lines displaced from the central magnetic circuit will bend around it along the surface itself (along the shortest path), thereby still crossing the area limited by the turns of the secondary. Analysis of the design forces one to abandon the current circuit design. You need a central magnetic core WITHOUT a hole. Let's look at the following diagram:

The main magnetic circuit is assembled from individual plates or rods of rectangular cross-section, and is a parallelepiped. The primary is placed directly on it. Its axis is horizontal and, according to the diagram, looks at us. The secondary is still a “puff pastry” made from Tesla bifilar cells. Now note that we have introduced an additional (secondary) magnetic circuit, which is “cups” with holes in their bottoms. The gap between the edge of the hole and the main central magnetic circuit (primary coil) must be minimal in order to effectively intercept the displaced magnetic lines and pull them towards themselves, preventing them from passing through the bifilars. Of course, it should be noted that the magnetic permeability of the central magnetic core should be an order of magnitude higher than that of the auxiliary one. For example: a central parallelepiped - 10,000, "cups" - 1000. In a normal (not saturated) state, the central core, due to its greater magnetic permeability, will draw magnetic lines into itself.

And now the most interesting part ;) . Let's take a closer look - what did we get?... And we got the most ordinary MEG, only in an “unfinished” version. In other words, I want to say that the classical performance MEG generator v.4.0 is a couple of times faster than ours best scheme, in view of its ability to redistribute magnetic lines (swinging the “swing”) to remove useful energy throughout the entire cycle of its operation. Moreover, from both arms of the magnetic circuit. In our case, we have a one-arm design. We simply do not use half of the possible efficiency.

Free energy, alternative energy

Electricity bills are an inevitable expense for anyone. modern man. Centralized power supply is constantly becoming more expensive, but electricity consumption is still growing every year. This problem is especially acute for miners, because, as you know, cryptocurrency mining consumes a significant amount of electricity, and therefore the bills for its payment may exceed the profit from. Under such conditions, it is worth paying attention to the fact that almost all Natural resources can be used to convert into electricity. Even in the air there is static electricity, all that remains is to find ways to use it.

Where can I get free electricity?

You can get electricity from anything. The only condition: a conductor and a potential difference are required. Scientists and practitioners are constantly looking for new alternative sources of electricity and energy that will be free. It should be clarified that free means no payment for centralized energy supply, but the equipment itself and its installation still costs money. True, such investments more than pay off later.

On this moment free electricity is obtained from three alternative sources:

Such methods are used both by ordinary consumers and on a large scale. For example, huge geothermal plants have been installed in Iceland and produce hundreds of MW.

How to make free electricity at home?

Free electricity in the apartment must be powerful and constant, so to fully ensure consumption, a powerful installation will be required. The first step is to determine the most suitable method. So, for sunny regions, installation is recommended. If solar energy is not enough then wind or geothermal power plants should be used. The latter method is especially suitable for regions located in relative proximity to volcanic zones.

Having decided on the method of obtaining energy, you should also take care of the safety and security of electrical appliances. For this home power station must be connected to the network through an inverter and voltage stabilizer to ensure current flow without sudden surges. It is also worth considering that alternative sources are quite capricious in terms of weather conditions. In the absence of appropriate climatic conditions, electricity generation will stop or be insufficient. Therefore, you should also acquire powerful batteries for accumulation in case of lack of production.

Ready-made installations of alternative power plants are widely available on the market. True, their cost is quite high, but on average they all pay off in 2 to 5 years. You can save money by purchasing ready installation, and its components, and then independently design and connect the power plant.

How to get free electricity at your dacha?

Connecting to a centralized energy supply system is a problematic process and often dachas are left without electricity for a long time. This is where installation can come to the rescue diesel generator or alternative extraction methods.

Dachas often lack a huge number of electrical appliances. Accordingly, energy consumption is significantly less. First you need to determine the predominant period of time that will be spent indoors. So, for summer summer residents, solar collectors and batteries are suitable, for the rest, wind methods.

You can also power individual electrical appliances or illuminate a room by collecting electricity from grounding. Scheme for obtaining free electricity: zero - load - ground. Voltage inside the house is supplied through the phase and neutral conductors. By including the third load conductor to zero in this circuit, from 12W to 15W will be directed into it, which will not be recorded by metering devices. For such a circuit, it is imperative to take care of reliable grounding. Zero and ground do not pose a risk of electric shock.

Free electricity from the ground

The earth is a favorable environment for generating electricity. There are three environments in the soil:

• humidity - drops of water;
• hardness - minerals;
• gaseousness - air between minerals and water.

In addition, the soil constantly undergoes electrical processes, since its main humus complex is a system in which a negative charge is formed on the outer shell, and a positive charge on the inner shell, which entails a constant attraction of positively charged electrons to negative ones.

The method is similar to that used in conventional batteries. To generate electricity from the ground, two electrodes should be immersed in the ground to a depth of half a meter. One is copper, the second is made of galvanized iron. The distance between the electrodes should be approximately 25 cm. The soil between the conductors is filled with saline solution, and wires are connected to the conductors, one will have a positive charge, the other will have a negative charge.

In practical conditions, the output power of such an installation will be approximately 3W. The charge power also depends on the composition of the soil. Of course, such power is not enough to provide energy supply in a private home, but the installation can be strengthened by changing the size of the electrodes or connecting the required number in series. After conducting the first experiment, you can roughly calculate how many such installations are needed to provide 1 kW, and then calculate the required amount based on average consumption per day.

How to get free electricity from thin air?

Nikola Tesla was the first to talk about generating electricity from thin air. The scientist's experiments have proven that between the base and the raised metal plate there is static electricity that can accumulate. Moreover, the air in modern world constantly undergoes additional ionization due to the functioning of many electrical networks.

The soil can serve as the basis for a mechanism for extracting electricity from the air. metal plate placed on the conductor. It should be placed above other nearby objects. The outputs from the conductor are connected to a battery in which static electricity will accumulate.

Free electricity from power lines

Power lines carry enormous amounts of electricity through their wires. An electromagnetic field is created around the wire carrying current. Thus, if you place a cable under a power line, an electric current is generated at its ends, the exact power of which can be calculated by knowing how much power the current is transmitted through the cable.

Another way is to create a transformer near power lines. A transformer can be created using copper wire and rod using the primary and secondary winding method. The current output power in this case depends on the volume and power of the transformer.

It is worth considering that such a system for obtaining free electricity is illegal, although there is no actual illegal connection to the network. The fact is that such wedging into the power supply system damages its power and can be punishable by fines.

Free electricity from surge protector

Many seekers of free electricity have probably found versions on the Internet that an extension cord can become a source of endless free energy, forming a closed circuit. To do this, you should take a surge protector with a wire length of at least three meters. Fold the cable into a coil with a diameter of no more than 30 cm, connect it to the socket of the electrical consumer, isolate all free holes, leaving only one more socket for the plug of the extension cord itself.

Next, the surge protector must be given an initial charge. The easiest way to do this is by connecting an extension cord to a functioning network, and then shorting it out in a split second. Free electricity from an extension cord will supply power lighting fixtures, but the free energy power in such a network is too small for anything more. But the method itself is quite controversial.

Free electricity from magnets

A magnet emits a magnetic field and, as a result, it can be used to generate free electricity. To do this, you should wrap a magnet with copper wire, forming a small transformer, which, by placing it near the electromagnetic field, you can receive free energy. The power of electricity in this case depends on the size of the magnet, the number of windings and the power of the electromagnetic field.

How to use free electricity?

When deciding to replace centralized energy supply with alternative sources, you should take into account all the necessary safety measures. To avoid sharp changes voltage, electric current to the devices must be supplied through voltage stabilizers. You should definitely pay attention to the dangers of each method. Thus, immersing electrodes in the soil implies subsequent flooding of the soil with a saline solution, which will make it unsuitable for further plant growth, and systems that accumulate static electricity from the air can attract lightning.

Electricity is not only useful, but also dangerous. Incorrect phasing can lead to electric shocks, and a short circuit in the network can lead to fires. Providing electricity to your home at home requires a detailed study of the methods and laws of physics.

It should also be taken into account that most methods do not provide stable power and depend on many factors, including weather conditions, which are impossible to predict. Therefore, it is recommended to either store energy in batteries, and have a backup power supply just in case.

Forecast for the future

Already now, alternative energy sources are widely used. The lion's share of electricity consumption comes from household electrical appliances and lighting. By replacing their power supply from centralized to alternative, you can significantly save your budget. Special attention Miners should consider alternative sources of power supply, since mining with a centralized power supply can take up to 50% of the profit, while mining with free power will generate net income.

More and more homes are being powered by solar panels or wind power plants. Such methods provide much less power, but are environmentally friendly sources of energy that do not cause harm. environment. Industrial alternative power plants are also being constructed.

In the future, this area will only be supplemented with new methods and improved analogues.

Conclusion

It is possible to extract electricity even from thin air, but to cover all consumption needs it is necessary to design an entire system of alternative electricity generation. You can take the easy route and buy ready-made solar panels or wind power plants, or you can put in the effort and assemble your own power plant. Now free electricity This is not a fully explored area and opens up a lot of opportunities for independent experiments.

In this article, we will consider a model of a powerful generator made of magnets, which is capable of generating electricity with a power of 300 watts. The frame is assembled from 10 mm thick duralumin plates. The generator consists of 3 main parts: housing, rotor, stator. The main purpose of the housing is to fix the rotor and stator in a strictly defined position. The rotating rotor should not touch the stator coils with magnets. The aluminum body is assembled from 4 parts. The corner layout provides a simple and rigid structure. The body is made on a CNC machine. This is both an advantage and a disadvantage of the development, since for a high-quality repetition of the model you need to find specialists and a CNC machine. The diameter of the discs is 100 mm.

You can also buy a ready-made electric generator in an online store.

Rotor of the electric generator I. Belitsky

Rotor is an iron axle. There are 2 iron disks with neodymium magnets located on them. An iron bushing is pressed between the discs on the axle. Its length depends on the thickness of the stator. Its purpose is to ensure a minimum gap between the rotating magnets and the stator coils. Each disk contains 12 neodymium magnets with a diameter of 15 and a thickness of 5 mm. Seats are made for them on the disk.

They need to be glued epoxy resin or other glue. In this case, it is necessary to strictly observe polarity. When assembled, the magnets should be positioned so that opposite each one there is another from the opposite disk. In this case, the poles must be different towards each other. As the author of the development himself (Igor Beletsky) writes: “It would be correct to have different poles, so that the lines of force would come out of one and enter the other, definitely S = N.” You can purchase neodymium magnets in a Chinese online store.

Stator device

A sheet of textolite 12 m thick was used as a base. Holes were made in the sheet for the coils and rotor bushings. The outer diameter of the iron coils that are installed in these holes is 25 mm. The inner diameter is equal to the diameter of the magnets (15 mm). The coils perform 2 tasks: the function of a magnetically conductive core and the task of reducing sticking when moving from one coil to another.

The coils are made of insulated wire 0.5 mm thick. 130 turns are wound on each coil. The winding direction is the same for all.

When creating a powerful generator from, you need to know that the higher the speed that can be provided, the higher the output voltage and current of the device will be for free energy.
