Science fiction writers sometimes invent projects that are many years ahead of the development of technology. Jules Verne already in his first story described a balloon, the rise of which can be changed by heating gas - now such balloons fly around the world. The beloved in Russia British science fiction writer Arthur Clark in 1945 proposed launching communication satellites into geostationary orbits, and nine years later indicated the possibility of using spacecraft to predict weather. Both ideas have long been put into practice with great benefit to humanity.

Isaac Asimov, a classic of American science fiction, also pampered readers with many brilliant technical forecasts. One of them is contained in a short story by Reason, which appeared in the April April issue of Astounding Science Fiction (in Russian, it was first published in the cult collection “I, Robot” under the heading “Logic”).

The action takes place on one of the space stations that supply energy to our planet. Its spherical body is surrounded by panels with photocells that convert the sun's rays into electric current, which feeds a gigantic microwave radiation generator. It is sent by a thin beam to a receiving station on Earth and there again converted into electricity. Simple, elegant and, most importantly, is absolutely feasible from the point of view of physics. True, fans of Asimov will remember that the robot Kyuty, responsible for the emitter’s work, rebelled, but ultimately the story ends with a happy ending.

It is very possible that in just seven years, the Asimov idea will become a reality - though without robots for now. It intends to implement the California-based Solaren Corporation, created by a group of engineers in the aerospace industry ...

In the literature, there is always a theme of saving electricity and extending the life of incandescent lamps. In most articles, a very simple method is proposed - switching a semiconductor diode in series with the lamp.

This topic has repeatedly appeared in the magazines "Radio", "Radio amateur", she did not bypass "Radioamator" [1-4]. They offer a wide variety of solutions: from the simple inclusion of a diode in series with a cartridge [2], the difficult manufacture of a "tablet" [1] and the "prescribing an aspirin bulb" [3] to the manufacture of an adapter cap [4]. Moreover, on the pages " "Radioamator" "flares up a quiet debate about whose" pill "is better and how to" swallow "it.

The authors took good care of the "health" and "durability" of the incandescent lamp and completely forgot about their health and the health of their family. "What's the matter?" - you ask. Just in those blinks that suggest masking with the help of a “milky” lampshade [3]. There may be an illusion of a decrease in blinks, but this will not make them smaller, and their negative impact will not decrease.

So, we can choose which is more important: the health of the light bulb or ours? Is natural light better than artificial? Of course! Why? There can be many answers. And one of them - artificial lighting, for example, incandescent lamps, blinks at a frequency of 100 Hz. Pay attention not to 50 Hz, as it is sometimes mistakenly believed, referring to the frequency of the electrical network. Due to the inertia of our vision, we do not notice flashes, but this does not mean at all that we do not perceive them. They affect the organs of vision and, of course, the human nervous system. We get tired faster ...

Despite the indisputable successes of the modern theory of electromagnetism, the creation on its basis of such directions as electrical engineering, radio engineering, electronics, there is no reason to consider this theory complete.

The main drawback of the existing theory of electromagnetism is the lack of model concepts, a lack of understanding of the essence of electrical processes; hence the practical impossibility of further development and improvement of the theory. And from the limitations of the theory, many applied difficulties also follow.

There are no grounds for believing the theory of electromagnetism to be the height of perfection. In fact, the theory has accumulated a number of omissions and direct paradoxes for which very unsatisfactory explanations have been invented, or there are no such explanations at all.

For example, how to explain that two mutually motionless identical charges, which are supposed to be repelled from each other according to the Coulomb law, are actually attracted if they move together a relatively long-abandoned source? But they are attracted, because now they are currents, and identical currents are attracted, and this has been experimentally proved.

Why does the electromagnetic field energy per unit length of a conductor with the current generating this magnetic field tend to infinity if the return conductor is moved away? Not the energy of the entire conductor, but precisely per unit length, say, one meter? ...

At the end of the last century, a young American physics student Edwin Hall made a discovery that entered 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, an electric current in itself appeared in the transverse circuit, as if from nothing. It was interesting, but there was no miracle here - an explanation was found quite quickly ...

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 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 an accessible part of it).These include the existence of anomalous points on the planet, anti-gravity 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 in our space (proton and electron) of electric charges of a positive and negative sign.

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 possessed 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 ...

A young man who had barely managed to take off his diapers, but already with a “mobile”, or a granny, in whose shopping bag a cell phone stumbles, no one is surprised today. The sign of the time, its attribute, as familiar and indispensable as a computer, television, electrical panel in the hallway. All this creates an electromagnetic background, completely invisible and inaudible. How environmentally friendly is it?

Science does not know, but warns ...

Some scare us with cancer, sexual impotence, dementia and miscarriages. Others reassure - it's okay, they even treat magnetic fields! In general, all the poison and all the medicine, only the dose makes it this or that, as the ancient Aesculapius said. The experts of the Research Institute of Occupational Medicine of the Russian Academy of Medical Sciences and the Center for Electromagnetic Safety at the Institute of Biophysics of the Ministry of Health of the Russian Federation took up the establishment of this "dose". To make it clearer: all devices consuming electricity, except for electric fields, also create magnetic ones.

These are high-voltage and cable lines, switchboards, transformers and wires of power supply systems, trolleybuses and trams, subways and commuter trains, household appliances included in the socket ... And if there are no problems with electric fields, they have been studied for a long time and are quite easily shielded (enough obstacles in the form of reinforced concrete wall or metal mesh), says the deputy director of the Center Eugene Bicheldey, science so far knows little about the biological effect of magnetic fields, and it is technically very difficult to defend against them and expensive. A person without special devices is not able to recognize their presence - he does not have such a sensory organ. Although science has established that magnetic fields can adversely affect living organisms. But how dangerous are they ...
