Secrets and mysteries of Nikola Tesla

Secrets and mysteries of Nikola TeslaTesla 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 ...

 

How to identify capacitor malfunction

How to identify capacitor malfunctionThe loss of performance of capacitors may occur due to:

i) a short circuit inside it;

b) a chain break inside it;

c) increase in leakage current;

d) decrease in capacity.

An inoperative capacitor can be determined using an ohmmeter, a special device for measuring capacitance, or a test circuit.

For a rough check of the suitability of capacitors, it is recommended to control them using resistance meters (ohmmeter, combined device - multimeter).

The verification procedure is as follows ...

 

The future of energy - superconducting power generators, transformers and power lines

The future of energy - superconducting power generators, transformers and power linesOne 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 allow us to 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 ...

 

How to connect the washing machine to the mains

How to connect the washing machine to the mainsSafe operation of the washing machine is paramount. To ensure this, it is necessary to organize the connection from the switchboard of a zero or ground bus with a cross section of at least 3 mm. In this case, the outlet should be replaced with a three-wire. The connection diagram is shown in the figure.

Often in apartments with a gas stove there is also a socket for an electric stove that is not used. It can be used to connect the washing machine, since the grounding wire is already in it.To do this, replace the socket for the electric stove with a standard socket with a grounding contact.

And we use an extension cord with a grounding contact.

I draw your attention to the fact that the ground wire must be insulated, it is strictly forbidden to connect it to heating radiators, water supply systems, gas supply systems ...

 

With the help of electric current, depression can be cured.

altCanadian 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 specific 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 - the area of ​​the brain located quite deeply. It is this site, scientists say, that plays a significant role in the regulation of human emotions, that is, 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 ...

 

How to find the right electrician to replace wiring in the house

altSo, in front of you is a "specialist" who is ready to start work in your apartment (house). How to determine that this electrician is exactly the one you were looking for, having phoned several companies and private masters?

1. The very first, a self-respecting master will take off his shoes and ask for slippers at the entrance to the apartment. Before starting work, he will warn you about places where, in his opinion, it will be dirty and will ask you to remove / hide objects that may get dirty.

2. The foreman (or foreman) who will work here directly should go for a measurement (initial inspection, budgeting). This condition will allow you to no longer repeat your conditions to each new representative, and the master will be able to take everything into account as correctly as possible and the error of the "third person" will be eliminated.

3. Electrician - a specialist does not start a conversation with money, but with the amount of work, conditions, your wishes.

4. A real electrician will find out ...

 

Electrification of the whole country, GOELRO plan and the era of lighting

Electrification of the whole country, GOELRO plan and the era of lightingThe 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 took great strides ...

 

The story of how Alex Exler tried to call an electrician

altThe light bulb in the suspended ceiling burned out, knocking out a machine gun. He turned on the machine, replaced the light bulb - it again burned out. After that, it turned out that the switch of the entire series of bulbs stopped working - the entire line is on and on. Well, something was short, a clear stump. Usually in such cases, nothing is turned on, but here - nothing is turned off.

I called the local housing office (or whatever). Although Zhekovsky electrician to trust to do something in the apartment - obviously did not want to. They are usually rare jerks (although there are happy exceptions), and they don’t know how to do a damn thing. Having learned about the problem, the Zhekovskaya dispatcher told me the same thing - they say they won’t figure it out. Uselessly. To the question of where to go, the dispatcher advised a rather large office, which has a website on the Internet and which solves a lot of all kinds of problems - directly Mr. Wolfe.

I call the office, please send an electrician. The dispatcher finds out what happened. I explain. Further dialogue. (Note that I haven’t said yet that an electrician should go specifically out of town - here usually good sums are still additionally covered up, but here it was immediately interesting even without a countryside.)

Static electricity in nature and technology

Static electricity in nature and technologyFor the first time, the electrification of liquids during crushing was seen at waterfalls in Switzerland in 1,786. Since 1913. the phenomenon is called the balloelectric effect. The effect of electrification is observed not only at waterfalls in open areas, but also in caves. Microscopic droplets of water and molecular complexes, which, when crushed, break away from the water surface and are carried into the environment, charge the air at the waterfalls. The most significant effect of air electrification is observed at the largest waterfalls in the world ...

Off the coast of the seas, air acquires a positive charge due to the spray of salt water. On the surface of the seas and oceans, water spray begins at a wind speed of more than 10 m / s, when scallops of foam appear on the waves. The ratio of positive charges to negative charges in the air above the Black and Azov Seas reaches 2.04 in the stormy sea, and 1.48 in swell.

The conqueror of the Jomolungma N. Tensing in 1953 in the area of ​​the southern saddle of this mountain peak at an altitude of 7.9 km above sea level at -30 ° C and a dry wind of up to 25 m / s observed strong electrification of icy canvas tents inserted one into the other. The space between the tents was filled with numerous electric sparks ...

 

Smart Home Timers

Smart Home TimersMany would be happy to have a “smart home” - so that everything would turn on and off “according to pike orders”. But not everyone can afford the complete set of this miracle of technology. And not everyone needs it in full. To increase the IQ of their apartment, two or three timers will be enough for someone.

You do not need any specialists to install them - just plug the timer into a power outlet, and any connected electrical appliance with a capacity of up to 3500 kW will begin to work according to a given schedule.

The timer will turn on the kettle on time in the morning so that you can drink coffee immediately after waking up. He will also turn off the TV if the audience falls asleep in front of the screen before the film ends. And having programmed the time of your favorite programs, you will never miss them, carried away by business.The compressor in the aquarium will also turn on and off like a clock - without your participation. And as many times as necessary ...

 

About Ilyich’s bulb

Ilyich’s bulb“Ilyich’s bulb” is the colloquial name in the USSR for a household incandescent lamp used without a plafond.
The phrase “Ilyich’s bulb” appeared after V. I. Lenin’s trip to the village of Kashino in 1920 on the occasion of the launch of a local “power station” with a wiring network made of old telegraph wires. Initially, the concept of “Ilyich’s bulb” referred to the electrification of Russia, especially rural areas.
The trip of V.I. Lenin to Kashino took place on November 14, 1920 and was timed to the holiday in honor of the opening of the power plant. The construction of the local power station and the power distribution network was inspired by the speech of V.I. Lenin at the XX Congress of the Komsomol, where he pointed out the need to develop an economy based on electricity. The distribution network was built at the expense of the agricultural partnership by the residents themselves in their personal time from a telegraph wire that had not been used for a long time. Dynamo car was made in Moscow. In one of the houses Vladimir Ilyich had a conversation with local peasants. After the conversation, V.I. Lenin and N.K. Krupskaya took pictures with the peasants, and then he spoke at a rally.

This trip had a big impact ...

 

Do not build under power lines!

Do not build under power lines!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 ...
