Union socket and extension cord

a hybrid of an ordinary outlet and the same ordinary extension cord.What is so sorely lacking at the right time for a person who keeps up with progress and keeps track of all the technical innovations? Of course, outlets.

According to the law of meanness known to all of us, the sockets in our apartments are for the most part located in the most uncomfortable way, which creates a lot of problems for us, but conducting new ones is quite expensive, and extension cords are constantly breaking and terribly interfering. There is no question of convenience and comfort in such situations, but now it is no longer a problem. The inquiring mind of a person is in constant creative search, trying to make life easier for his master.

Another such “relief” this time was a hybrid of an ordinary outlet and the same ordinary extension cord ...

 

Superbright LEDs - the technological revolution in electric lighting

Superbright LEDs - the technological revolution in electric lightingMany people know that modern LEDs are more effective than incandescent lamps, and some models can argue with fluorescent lamps. But rarely does anyone think about what changes these technologies promise us.

Almost two trillion dollars - so many new LEDs will save earthlings in the next 10 years, provided they are widely implemented. In energy units, the savings will be expressed in 18.3 terawatt hours. Reducing CO2 emissions over this “LED” decade will be 11 gigatons, and oil consumption will drop by almost a billion barrels. And 280 average power plants can be closed.

Yes, professors Jung Kyu Kim and Fred Schubert from Rensselaer Polytechnic Institute approached the forecast of the future of solid-state lighting systems. They tried to go beyond the scope of saving electricity "for one house" and imagine what our world will be like, in which LEDs will become much more widespread ...

 

First nanoelectric motor

First nanoelectric motorGerman theorists from the University of Augsburg have proposed an original model of an electric motor operating on the laws of quantum mechanics. A specially selected external alternating magnetic field is applied to two atoms placed in a ring-shaped optical lattice at a very low temperature. One of the atoms, which scientists called the “carrier”, begins to move along the optical lattice and after a while reaches 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 is called a quantum atomic engine.

The first working electric motor was designed and demonstrated in 1827 by the Hungarian physicist Agnos Jedlic. The improvement of various technological processes leads to the miniaturization of various devices, including devices for converting electrical or magnetic energy into mechanical energy. Almost 200 years after the creation of the first electric motor, their sizes reached the micrometer threshold and stepped into the nanometer region.

One of the many micro / nanoscale electric motor projects was proposed and implemented by American scientists in 2003 in an article ...

 

Hitachi gets electricity from the air

Hitachi gets electricity from the airHitachi has developed a new technology for generating electricity, using naturally occurring vibrations in the air with an amplitude of several micrometers.

HITACHI has developed a new technology for producing electric current through the use of 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, interest in it is very high due to the fact that such generators can work in any weather and natural conditions, which they cannot boast of, for example, solar panels ...

 

Heating cables: types and applications

Heating cables: types and applicationsHeating cables - a specific type of cable products that convert electrical energy into heat for heating and perform the function of a receiver of electrical energy, rather than a transmission line.Heating cables are significantly different from ordinary cables and wires, the purpose of which is to transmit electrical energy with the least loss and with a slight voltage drop not the line length (usually not more than 5%).

The heating cable is used as heating sections, i.e. segments of a certain length, and at this length there is a complete drop in the applied voltage. Therefore, the heating section should be considered as a conventional receiver of electrical energy (as one of the types of electric heating elements) ...

 

Daedalus' Inventions: Vibrating Tram

Daedalus' Inventions: Vibrating TramMost vehicles need shock absorbing suspensions to ensure smooth ride. The exception is air cushion devices (WUAs), but they have to pay for the softness of the need to continuously pump a huge amount of air. Therefore, Daedalus is trying to construct a new mode of transport, which occupies an intermediate position between wheeled transport and WUAs.

Daedalus’s car (the prototype of which was a vibratory conveyor) has instead of wheels special runners, or “shoes”, installed along the entire length of the device and performing fast vertical vibrations, so that the vehicle moves forward as if with quick short jumps.

If the shoes are sufficiently elastic (for example, made from the wonderful rubber used to make baby balls), then the energy loss will be small and the power spent on movement will be small.

The speeds of the new transport, which can be considered as a logical development of the principle ...

 

Thermoelectric effect and cooling, Peltier effect

Thermoelectric effect and coolingThe economic efficiency of using thermoelectric refrigerators in comparison with other types of refrigerating machines increases the more, the smaller the volume of the cooled volume. Therefore, the most rational at the present time is the use of thermoelectric cooling for household refrigerators, in food liquid coolers, air conditioners, in addition, thermoelectric cooling is successfully used in chemistry, biology and medicine, metrology, as well as in commercial cold (maintaining the temperature in refrigerators) , refrigeration transport (refrigerators), and other areas

The effect of the occurrence of thermoEMF in soldered conductors is widely known in the art, the contacts (junctions of junctions) between which are maintained at different temperatures (Seebeck effect). In the case when a constant current is passed through a circuit of two dissimilar materials, one of the junctions starts to heat up, and the other starts to cool. This phenomenon is called the thermoelectric effect or the Peltier effect ...

 

About electronic meters and ASKUE for "dummies"

About electronic meters and ASKUE for An electronic counter is a converter of an analog signal to a pulse repetition rate, the calculation of which gives the amount of energy consumed.

The main advantage of electronic meters compared to induction ones is the absence of rotating elements. In addition, they provide a wider range of input voltages, make it easy to organize multi-tariff metering systems, and have a retrospective mode - i.e. allow you to see the amount of energy consumed for a certain period - usually monthly; they measure power consumption, easily fit into the configuration of ASKUE systems and have many more additional service functions.

A variety of these functions lies in the microcontroller software, which is an indispensable attribute of a modern electronic electricity meter.

Structurally, the electric meter consists of a housing with a terminal block, a current measuring transformer and a printed circuit board on which all electronic components are installed.

The main components of a modern electronic meter are ...
