Metamaterial for enhancing magnetic fields

Metamaterial for enhancing magnetic fieldsProfessor at Duke University (Durham, North Carolina, USA) Yaroslav Urzhumov proposed a method for amplifying the magnetic component of electromagnetic waves without increasing their electrical component. The fact is that biological tissues for magnetic fields are transparent, and it would be useful to learn how to strengthen precisely the magnetic component of electromagnetic waves.

This would open the way to the creation of safe levitating trains, to the construction of new wireless energy transmission systems, and to the solution of a number of other problems where there is a need for strong alternating magnetic fields, and at the same time it should be safe for humans. New systems will be more economical and safer than existing analogues. To obtain the desired result, Yaroslav Urzhumov proposed the use of magnetically active metamaterial, due to which it is possible to obtain sufficiently strong ...

 

What are supercapacitors

What are supercapacitorsOn June 7, 1962, Robert Reitmayer, a chemist at the American Standard Oil Company (SOHIO) in Cleveland, Ohio, filed a patent application detailing the mechanism for storing electrical energy in a double-layer capacitor.

If, in a conventional capacitor, aluminum plates, traditionally, were insulated with a dielectric layer, then in the embodiment proposed by the inventor, the emphasis was placed directly on the material of the plates. The electrodes had to have different conductivity: one electrode had to have ionic conductivity, and the other - electronic. Thus, in the process of charging a capacitor, there would be a separation of electrons and positive centers in the electronic conductor, and separation of cations and anions in the ionic conductor. An electronic conductor was offered ...

 

Using the energy of gravity - how is it possible

Using the energy of gravity - how is it possibleIn the early 2000s, Chinese inventors Lawrence Tseng and Li Cheng (Lawrence TSEUNG, Cheung LEE) proposed a method of extracting energy from gravity based on their adjusted pendulum theory. They realized that if you push the pendulum, then it immediately begins to withdraw gravitational energy.

If the momentum of force F continues to be applied to the pendulum in resonance, then it will continue to extract gravitational energy. This energy can be extracted, for example, if the metal pendulum is forced to cross the lines of the magnetic field, then mechanical energy will be converted into electrical energy. Although the swinging motion of the pendulum begins to slow down, the pendulum can be accelerated again due to the impulse of force F. The swinging motion can even be replaced by rotational, for a more effective implementation of this principle. Such devices can work everywhere, even on the moon, because gravitational energy is unlimited ...

 

What is nanoelectronics and how does it work

What is nanoelectronicsThe field of electronics engaged in the development of technological and physical foundations for the construction of integrated electronic circuits with element sizes less than 100 nanometers is called nanoelectronics. The term "nanoelectronics" itself reflects the transition from the microelectronics of modern semiconductors, where the sizes of elements are measured in units of micrometers, to smaller elements - with sizes of tens of nanometers.

With the transition to nanoscale, quantum effects begin to dominate in the schemes, revealing many new properties, and, accordingly, marking the prospects for their useful use. And if for microelectronics quantum effects often remained parasitic, because for example, with the decrease in the size of the transistor, the tunnel effect begins to interfere with its operation, then nanoelectronics, on the contrary, is called upon to use such effects as the basis for nanoheterostructured electronics ...

 

Disney Wireless Charging Room - How It Works

Disney Wireless Charging Room - How It WorksThe Walt Disney Company, known worldwide for its cartoons and films from Disney Studios, interacts extensively with various laboratories as part of an informal collaboration with Disney Research. So, most recently, the company's engineers created a prototype of a room in which various electronic devices can be charged wirelessly.

The QSCR technology - Quasistatic Cavity Resonance, which translates from English as “quasistatic cavity resonance”, is implemented in the design of the room. This technology involves the wireless supply of energy inside the volume of a single room, so that mobile devices inside the room could be charged without cable. According to the engineers, in the future offices will be equipped with such charging technologies. Typically, a person, to charge a tablet, phone or other electronic gadget, has to look for a power outlet ...

 

Vaneless turbines - a new type of wind generator

Vaneless turbines - a new type of wind generatorAlternative energy specialists have long formed a stereotype regarding how correct and efficient wind generators should look. This state of affairs is not at all surprising, because wind turbines are built every year around the world, and these are always huge structures with blades, similar to giant windmills. As for the vaneless wind generators, the attitude towards them, as a rule, among alternative people is very, very skeptical.

Nevertheless, developers of new solutions are in no hurry to stop in their enthusiasm. And so, in 2015, the Spanish company Vortex Bladeless proposed a new version and a ready-made solution model, showing how wind generators can be arranged that are not inferior in efficiency to traditional blade ones, but surpassing them both in safety and in production efficiency ...

 

Carbon batteries replace lithium

Carbon batteries replace lithiumSince 2014, the US-Japanese company Power Japan Plus, engaged in the search and development of materials for high-performance batteries, has launched the production of a new type of battery. Scientists from Kyushu University took an active part in the development. These batteries basically have an organic electrolyte, which, however, works with a cathode and anode made from a carbon-based composite, and carbon for batteries is made from cotton, coffee beans or bamboo.

The new batteries are called Ryden (Ryden dual carbon battery). Unlike today's popular lithium-ion batteries, Ryden's dual-carbon batteries are the most efficient and most environmentally friendly. Rare and heavy metals are not used here, so the batteries are not expensive and are completely recyclable. This is currently the best way ...

 

Solar shingles Tesla

Solar shingles TeslaIn the summer of 2016, one of the founders and the current head of Tesla Motors, Elon Musk, proposed the merger of SolarCity and Tesla Motors. The leader in the installation of solar panels in California, the energy company SolarCity, has been holding a high leadership position for ten years, and today it ranks second in the United States. And so, before the end of the year, November 17, an effective meeting of Ilon Mask with shareholders took place, the merger was resolved positively, and all that remained was to settle the legal side of this grandiose promising step.

According to the plan of the Mask, in the summer of 2017, consumers will be given the opportunity to buy Solar Roof shingles for their homes. The tile will be a prefabricated solar panel, and in appearance from the ground it will be very similar to ordinary tiles, with the only difference being that the roof will now be able to generate electricity ...
