Once people had no idea that in nature there is electricity, and now, when the local substation accident occurs, it is difficult to stand for several hours, until eliminate breakage.People have long been accustomed to large transformers, poles and high-voltage lines, cords, cables and sockets, and for a long time do not pay attention to them.All this is so firmly established in our minds, that we even do not think that the transfer of power can occur as something different.Fortunately, among us there are geniuses who do not leave hopes to invent a more advanced and sophisticated technology, and constant perseverance and experiments yielded very interesting results.
single-wire transmission of electricity
In 1990, Russian engineer S. Avramenko conducted a series of successful experiments, which resulted in a three-meter for single-line, he managed to convey electricity, which would be enough for a load of 1.3 kW.The installation consisted of a generator operating at a frequency of 3-15 kHz, and a step-up transformer.During the test, the inventor of the left one end of the secondary winding of the transformer free, and the second connected load, consisting of a transmission line with a diode bridge and a conventional incandescent lamp.Variants were also when the diode bridge is replaced by two diodes connected in antiparallel.Subsequently, such a scheme called fork Avramenko.
most curious circumstance of the experiment was that the transfer of power, and to be precise, its power, not only dependent on the resistance of the conductor.There is no clear scientific explanation for it yet, but imagine what prospects promise to humanity such superconductivity!Indeed, instead of the copper wire can be used, and water, and the earth and even plastic, i.e. any conductor regardless of its resistance.Today the works Avramenko and his colleagues have shown great interest in aliens and themselves invention marked a gold medal N. Tesla and a gold medal of the Brussels Salon of Innovations.
energy transfer by air
High conductivity - is good, but the lack of wires even better.Apparently, the conclusion made by scientists around the world who are inspired by Tesla's experiments on the new discovery.Today, wireless power transmission gradually changes from science fiction to the real reality.So, Intel in August 2008 by IDF, presented its new project - WiTriCity (short for Wireless Electricity).As a demonstration of the viewers has been shown the installation of the two antennas, one of which create an electromagnetic field around itself, which, in turn, induces an alternating current in the second loop antenna.This energy is enough to glow 60-watt bulb at a distance of 0.6 to 1 m. Subsequently, the company has developed a wireless charger for mobile gadgets, acting at a distance of 2.5 meters, and promises to surprise us with new products.Meanwhile, Korean scientists have decided to create a wireless power supply for any kind of electric.The new technology, called OLEV (short for On-line Electric Vehicle) charging requires municipal vehicles on the move, as well as in the parking lot and prolonged parking.New electricity transmission was successfully tested and will soon be used in ports, airports, railways and urban electric transport.As we can see, the new technologies are gradually being introduced to life, and maybe in the future our grandchildren will forget what adapters and tees, and power lines and transformers only see in pictures the history books.
