Engineers from Kyoto University have designed and assembled the first device that can store and store electromagnetic radiation with the preservation of its phase properties. The description of the "trap" is posted as a preprint in the archive of Cornell University, and its brief structure is described by the Technology Review blog.
American physicists created the new kind carbon nanotubes suitable for use as a material for weaving heavy-duty and electrically conductive "threads", and published instructions for their creation in the journal Science.
“Finally, we managed to create a fiber from nanotubes with properties that no other material possesses. It looks like an ordinary black cotton thread, but combines the properties of metal wires and strong carbon tubes,” said Matteo Pasquali, head of the physicist group ( Matteo Pasquali of Rice University in Houston (USA).
Acti9 is the 5th generation of modular systems from Electric. The previous, 4th generation was the Multi9 series, which has become the most famous product in the world in its class. Multi9 appeared many years ago with the release of the C32 series (then C45). Even the fact that the majority of Chinese-made devices on the Russian market are copies of C32 and C45 devices (the 3rd generation of modular systems from Electric) speaks for the long-term popularity of this range.
Automatic switches of the new generation Compact NSX, made in a molded case, in a molded case, are used for currents from 100 to 630A at objects of absolutely any scale and purpose - from office buildings to the largest enterprises. Electric's Compact NSX circuit breakers are used to protect distribution networks, long cables, motors and generators.
The flow of current in conductors is always associated with energy losses, i.e. with the transition of energy from the electrical form to the thermal form. This transition is irreversible, the reverse transition is associated only with the performance of work, as thermodynamics says. There is, however, the possibility of converting thermal energy into electrical energy and using the so-called. thermoelectric effect, when two contacts of two conductors are used, one being heated and the other being cooled.
In 1996, engineer Roy Kuennen wrestled with a solution to a problem: how to make an Amway Corp. household water filter. didn't break? The filter killed bacteria using an ultraviolet lamp, but for this it had to be immersed in water. The wires that supplied the lamp with electricity were rusting. Then the engineer Kuennen had a crazy idea: remove the wires and power the lamp remotely - using a magnetic coil.
While Kuennen struggled with the water filter, the wireless revolution was already in full swing - starting in the 90s, it gave us cellular telephone, Bluetooth and Wi-Fi, but only in recent years has begun to cover the field of power supply. Several companies are now looking for ways to power mobile phones, PDAs, laptops and other gadgets directly without having to plug them into the grid.
AT late XIX century, the discovery that electricity could make a light bulb glow sparked an explosion of research aimed at finding the best way transmission of electricity.
At the head of the race was famous physicist and inventor Nikola Tesla, who developed the grandiose project. Unable to believe in the reality of creating a colossal network of wires covering all cities, streets, buildings and rooms, Tesla came to the conclusion that the only feasible method of transmission was wireless. He designed a tower about 57 meters high, which was supposed to transmit energy over a distance of many kilometers, and even began building it on Long Island. A number of experiments were carried out, but the lack of money did not allow the tower to be completed. The idea of power transmission over the air dissipated as soon as it turned out that the industry was able to develop and implement a wired infrastructure.
Everyone knows that no one is immune from the consequences of storms, hurricanes, storms and other natural disasters. Therefore, it is worth soberly realizing that the next downpour with the same probability can leave without light, both a small office and a huge corporation. What to do in case of a cable break or some kind of failure? Call an electrician? Or rent a robot that will do all the work on its own much faster, and possibly better. Say fantasy? Of course, who will develop electrical robots if there are more interesting applications for these silicon creatures. And you don't have to go far - robot singers and bartenders, nannies and teachers, doctors, toys. And here is where I disagree.
Scientists have created a robot that, offline, will be able to independently check or diagnose many kilometers of power cable, identify problems and possibly even identify "preliminary" faults that, in the future, can cause problems in the network.
Professor, electronics engineer Alexander Mamishev told the press that such a development is the first in the industry ...
The specifics of the development of modern civilization, especially in the last ten years, are radically changing our lives. Two trends deserve the most attention.
The first is the rapid development of everything related to computer technology. This is not only a computer in every home and workplace, not only the Internet and "toys". If you look more closely, then we have all been hostages of computer technology for a long time. Almost any device now incorporates a control chip, which, in principle, is the same small computer. This is TV and washing machine, and mobile phone, and a camera, and a keychain to the car, and the car itself ...
Now in my office at work there are about 60! CPU controllers... This is already very serious! If earlier a microprocessor cost tens and hundreds of dollars, now you can buy a control chip for less than a dollar!
The second trend is the increase in the cost of energy resources, and everything related to the mining industry...
The economic efficiency of the use of thermoelectric refrigerators in comparison with other types of refrigeration machines increases the more, the smaller the cooled volume. Therefore, at present, the most rational use of thermoelectric cooling is for household refrigerators, food liquid coolers, air conditioners, in addition, thermoelectric cooling is successfully used in chemistry, biology and medicine, metrology, as well as in commercial refrigeration (temperature maintenance in refrigerators) , refrigeration transport (refrigerators), and other areas
In technology, the effect of the occurrence of thermoEMF in soldered conductors is widely known, contacts (junction points) between which are maintained at different temperatures (Seebeck effect). In the case when a direct current is passed through a circuit of two dissimilar materials, one of the junctions begins to heat up, and the other to cool. This phenomenon is called the thermoelectric effect or the Peltier effect...
One of the main directions in the development of science is the theoretical and experimental research in the field of superconducting materials, and one of the main directions in the development of technology is the development of superconducting turbogenerators.
Superconducting electrical equipment will make it possible to sharply increase the electrical and magnetic loads in the elements of devices and, due to this, to drastically reduce their dimensions. In a superconducting wire, a current density is allowed that is 10 ... 50 times higher than the current density in conventional electrical equipment. Magnetic fields can be brought up to values of the order of 10 T, compared to 0.8...1 T in conventional machines.
Maglev or Maglev(from English magnetic levitation) is a train on magnetic suspension driven and controlled by magnetic forces. Such a train, unlike traditional trains, does not touch the rail surface during movement. Since there is a gap between the train and the running surface, friction is eliminated and the only braking force is the drag force.
The speed achievable by a maglev is comparable to the speed of an aircraft and makes it possible to compete with air communications at short (for aviation) distances (up to 1000 km). Although the very idea of such transport is not new, economic and technical limitations did not allow it to be fully deployed: the technology was implemented for public use only a few times. At present, Maglev cannot use the existing transport infrastructure, although there are projects with the location of elements of the magnetic road between the rails of a conventional railway or under the roadbed.
Hitachi developed new technology generating electricity using vibrations naturally occurring in the air with an amplitude of several micrometers.
HITACHI has developed a new technology for generating electric current by using the natural processes of vibrations that occur in the air, which pass with an amplitude of a couple of micrometers. Despite the fact that this technology provides a very low electrical voltage, there is a great interest in it due to the fact that such generators can operate in all weather and natural conditions, which, for example, solar panels cannot boast of ...
British scientists have developed a new alternative device to generate electricity, writes The Daily Mail. This device looks like a giant snake, but it is possible that in five years it will be used everywhere, and not only in the United Kingdom.
The unusual generator "Anaconda" (Anaconda) is a huge rubber pipe (more than 180 m long), one end of which is attached by a cable to a float, anchored in turn at the bottom of the ocean, and the other one dangles freely. There is also water inside the pipe.
German theorists from the University of Augsburg proposed an original model of an electric motor operating on the laws quantum mechanics. A specially selected external alternating magnetic field is applied to two atoms placed in an annular optical lattice at a very low temperature. One of the atoms, which scientists called the "carrier", begins its movement along the optical lattice and after a while reaches a constant speed, the second atom plays the role of a "starter" - thanks to the interaction with it, the "carrier" begins its movement. The whole structure was called the quantum atomic engine.
Technological progress in the LED industry. What is the secret to the longer life of the new LED indoor luminaires?
The market for LED technology is growing rapidly and the range is filled with various new products. In general, for LED lighting, this market niche is an unplowed field. After all, the elements themselves, LEDs, are practically durable, mainly due to low heat transfer and low consumption, they work on average 50,000 hours, namely 5 years. This makes it possible to assemble ready-made equipment, where it is not necessary to provide for the dimensions of the light bulbs or the possibility of replacing light elements, so that LEDs can be turned into light bulbs, spotlights, lamps, in a free artistic form and format, you can combine colors, enhance pointiness with the help of optical lenses...
The reason for switching to energy-saving LED products. Comparison and simple mathematical calculation of savings and benefits from the purchase in the long run.
Today, many people talk about new energy-saving technologies. That in the near future the traditional "light bulbs of Ilyich" are living out their Age and a new era is coming, or rather, the electrical LED revolution.
This issue has risen to the state level. Starting with the President, who instructed the state corporations Rosstekhnologii and Rosnano to introduce Energy Saving Technologies, due to the fact that electricity is not spent efficiently and it's time to break stereotypes and keep up with the times. Factories will be built in a short time on the territory of Russia, where they will produce LED products and there are already laboratories for their manufacture, although there are very few of them and the cost is still high compared to LEDs from Asian countries.
What do they offer us modern technologies and the State represented by these technologies? ...
Comparison of a conventional LVO ceiling lamp with an LED counterpart.
A revolutionary Age in lighting fixtures is coming. The best universal technology for lighting equipment, selected at the state level, it is an energy-saving LED technology. And there are technological innovations, there are a lot of them, they replace, like conventional incandescent lamps, lighting spotlights, architectural and interior lighting. There are solutions for offices and, in general, for their upcoming construction, using cost-effective lighting fixtures.
Namely, where I was getting at, in the last sentence, this LED lights built into the ceiling. Let's see if there is any benefit in its use and how economical this device is?

Heating cables are a specific type of cable products that convert electrical energy into thermal energy for the purpose of heating and perform the function of a receiver of electrical energy, and not a transmission line. Heating cables differ significantly from conventional cables and wires, the purpose of which is to transmit electrical energy with the least losses and with a slight voltage drop over the length of the line (usually no more than 5%).
Many people know that modern LEDs are more efficient than incandescent lamps, and some models can compete with lamps. daylight. But rarely does anyone think about what changes these technologies promise us.
Almost two trillion dollars - this is how much new LEDs will save earthlings over the next 10 years, subject to their widespread introduction. In energy terms, the savings would be 18.3 terawatt-hours. The reduction in CO2 emissions over this "LED" decade will be 11 gigatons, and oil consumption will be reduced by almost a billion barrels. And 280 average power plants can be closed.
Yes, professors Chung Kyu Kim and Fred Schubert of Rensselaer Polytechnic Institute took a big approach to predicting the future of solid-state lighting systems. They tried to go beyond "single house" electricity savings and imagine what our world would be like in which LEDs would become much more widespread than they are today. And most importantly, they calculated what technical heights we should expect from the same LEDs in the coming years...
