At the end of the last century, a young American physics student Edwin Hall made a discovery that wrote his name in physics textbooks. He conducted a simple, “student” experiment — he studied the propagation of current in a thin metal plate placed between the poles of a strong electromagnet. Students of all universities undergo laboratory practice, where they are taught with simple examples the skill of the experiment. So it was this time. A humble student could not have imagined that his simple experience would give rise to an avalanche of research, some of which will be marked by the most honorable scientific award - the Nobel Prize.

The device with which Hall worked consisted of two crosswise arranged electrical circuits - this is how they tie a box of sweets with a ribbon. The chains differed in that one of them contained an electric battery and the current from it passed along the plate, the other, transverse, had no current sources and simply connected the edges of the plate.

As expected, in the case when the electromagnet was turned off, the instruments recorded the current flow only along the plate — in the circuit with the battery — and its absence in the “empty” transverse circuit. No wonder. However, as soon as the electromagnet turned on, in the transverse circuit, as if from nothing, an electric current appeared on its own. It was interesting, but there was no miracle here - an explanation was found quite quickly ...

Magnetoplan or Maglev (from English magnetic levitation) is a train on a magnetic suspension, driven and controlled by magnetic forces. Such a composition, unlike traditional trains, does not touch the rail surface during movement. Since there is a gap between the train and the surface of movement, friction is eliminated, and the only drag force is the force of aerodynamic drag.

The speed achievable by the Muggle is comparable to the speed of the aircraft and allows you to compete with air traffic at small (for aviation) distances (up to 1000 km). Although the very idea of ​​such a transport is not new, economic and technical limitations did not allow it to unfold fully: for public use, the technology was implemented only a few times. Currently, Maglev can not use the existing transport infrastructure, although there are projects with the location of the elements of the magnetic road between the rails of a conventional railway or under the track.

At the moment, there are 3 main technologies for magnetic suspension of trains:

1. On superconducting magnets (electrodynamic suspension, EDS) ...

Despite the centuries-old study of the history of Egypt for modern man, the secrets of ancient civilization and its knowledge remain unsolved.

Exploring the heritage of ancient Egypt in the drawings of temples, tombs, on stone slabs, in texts, etc., you can see the mysterious technical devices that they owned, information about which was transmitted to descendants.

Among them are: lamps, sources of static energy, as well as mechanisms that use this energy to perform labor-intensive work.

All material bodies have electrostatic radiation of different strengths. The most powerful of them were used by ancient civilizations.

Mankind has repeatedly encountered natural phenomena and experiments that cannot be explained from the standpoint of modern science (in any case, from the standpoint of its accessible part). These include the existence of anomalous points on the planet, antigravity effects, transitions to other dimensions of people and objects, etc. These phenomena, as a rule, occur in the presence of electric and magnetic fields, demonstrate the relationship of gravitational space-time with electromagnetic fields.

Each elementary particle of matter carries not only gravitational, but also an electric charge, however, in general, the electric potential in our space is equal to zero. The lack of electric potential in the gravitational field-ether is due to two factors:

1. Equality of the ether-forming pair of particles of our space (proton and electron) of electric charges of positive and negative signs.

2. The number of protons and electrons is exactly equal in the entire closed volume of the metagalaxy.

These factors are a property of matter, a property of the ether field of the constant gravitational potential of the closed space-time of our metagalaxy. An electric field can be present only in local regions of space-time. From the point of view of a unified theory of field, space and time, radiation crossing a similar region acquires two components: electromagnetic and magnetogravitational. In the space region of double electrogravity nature, not only a change in the electric, but also a change in the gravitational field leads to the formation of a magnetic field. The amplitude of the electromagnetic and magnetogravitational component of single oscillations depends on the potential of the field of the opposite nature (gravitational and electric, respectively).

A change in the magnetic field in space-time of a double nature forms both an electric and a gravitational field, depending on the potential of the field of the opposite nature. If the electric potential is equal to zero, then the energy of the magnetic field completely transfers to the electric field. In an ideal gravitational ether, there are only electromagnetic waves. In the presence of an electric potential of a positive or negative sign, part of the magnetic energy is spent on the formation of a gravitational alternating field, and the larger the magnitude of the electric potential, the greater the amplitude of the gravitational component of the single electromagnetic-gravitational vibrations.

The gravitational ether of our space is an inexhaustible source of electromagnetic energy. Currently, devices have already been created that receive electricity "from nothing": from space-time of a gravitational nature. Such devices lay the foundation for the energy of the future ...

Tesla was appropriated by the clairvoyant's abilities, he had a pronounced gift of foreboding. The inventor claimed that he could completely disconnect his brain from the outside world. And in this state, “outbursts of enthusiasm”, “inner vision” and “bouts of hypersensitivity.” Descended upon him. At that moment, the scientist believed, his mind penetrated into the mysterious subtle world.

Once friends from Philadelphia, who were visiting him, were going to return home by train. But Tesla felt a strange desire to detain them in any way. The train on which they were supposed to return was wrecked.

Another time he had a dream that his sister was mortally ill and died. And this turned out to be true, although he did not receive any information about her illness.

And when the financial beneficiary of Tesla J.P. Morgan bought a ticket for the first flight of the Titanic, the inventor categorically insisted that he refuse the trip. Morgan believed Tesla and refused a prestigious flight.

Tesla was a really amazing person, a phenomenally successful engineer, inventor and scientist, who also did without abstracts and drawings ...

One of the main directions of the development of science outlines theoretical and experimental studies in the field of superconducting materials, and one of the main directions of the development of technology is the development of superconducting turbogenerators.

Superconducting electrical equipment will dramatically increase electrical and magnetic loads in the elements of devices and thereby dramatically reduce their size. In a superconducting wire, a current density of 10 ... 50 times the current density in conventional electrical equipment is permissible. Magnetic fields can be brought to values ​​of the order of 10 T, compared with 0.8 ... 1 T in conventional machines. Given that the dimensions of electrical devices are inversely proportional to the product of the permissible current density and magnetic induction, it is clear that the use of superconductors will reduce the size and weight of electrical equipment many times!

According to one of the designers of the cooling system of new types of cryogenic turbogenerators, the scientist I.F. Filippov, there is reason to consider the task of creating economical cryoturbogenerators with superconductors solved. Preliminary calculations and studies give hope that not only the size and weight, but also the efficiency of new machines will be higher than that of the most advanced generators of a traditional design ...

Canadian researchers led by Dr. Andrés Lozano of the University of Toronto have developed a new treatment for depression. They found that patients with severe depression who could not be corrected with medication could benefit from exposure to a certain area of ​​the brain.

Currently, the most common way to treat depression is with medication. But it has several disadvantages: significant side effects and contraindications. Moreover, sometimes severe depression is generally not amenable to correction with drugs.

Therefore, back in 2002, Canadian scientists began to develop a new, therapeutic method of treatment. Its essence lies in the impact on the part of the isthmus of the cingulate gyrus - a zone of the brain located deep enough. It is this site, scientists say, that plays a significant role in the regulation of human emotions, that is, it is associated with the development of depressive states.

To stimulate the isthmus, the doctors implanted electrodes into the patients through which weak impulses of electric current were passed ...

The famous phrase about "electrification of the whole country" was not invented by Lenin. And the pride of the Bolshevik GOELRO-Dneproges plan was designed before October. The revolution and the Civil War only delayed the electrification of Russia

Before the solemn inclusion of the Ilyich bulb in the village of Kashino near Moscow, another 40 years remained. This, however, did not prevent enthusiasts from introducing electricity into Russian life to light hitherto unprecedented electric lamps on the Liteiny Bridge in St. Petersburg in 1880 - after all, the innovators did not know that in the Soviet future it would be the first Kashin lamp to be declared the first in Russia. It was completely different for them: the monopoly of the owners of gas lamps in the imperial capital — they had the exclusive right to cover St. Petersburg. But for some reason the Liteiny Bridge fell out of this monopoly. The ship with an electrical installation that lit the lanterns was also brought to him.

Just three years after this demonstration of “antitrust light presentation”, the first power station with a capacity of 35 kilowatts was opened in St. Petersburg - it was located on a barge moored at the Moika embankment. There were installed 12 dynamos, the current from which was transmitted by wire to Nevsky Prospect and lit 32 street lamps. The station was equipped by the German company Siemens and Halske, at first it played a major role in the electrification of Russia.

Three years later, in 1886, the Electric Lighting Society was founded in St. Petersburg, bringing together scientists and businessmen in the "electrification of the whole country" (these "Leninist" words were already written down in the charter).Most of the company's shareholders were foreigners - primarily the same Siemens concern - but the technical personnel were Russian.

Although in the field of energy, the Russian Empire lagged noticeably behind Western countries, the development of the industry at the turn of the nineteenth and twentieth centuries went by leaps and bounds ...
