Mr. Electric is taking a look at the electric feud between Nikola Tesla and Thomas Edison. Waco, Texas (PRWEB) July 03, 2014 One studied alternating current (AC), the other, direct current (DC). And yet, the world would not be where it is today without their contributions to science and electricity. In light of Nikola Tesla’s birthday on July 10, Mr. Electric is taking a look at the electric feud between Nikola Tesla and Thomas Edison. Tesla and alternating current The main focus for...

DOE/Brookhaven National Laboratory Findings unequivocally link 2 'personality' changes of electrons at critical point Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by a mysterious phase that emerges as charge carriers are added that appears to compete with superconductivity. It's also been a mystery why, within this "pseudogap"...

Scalable, AC/DC conversion technology offers data centersincreased power efficiency, greater reliability, and significant space savings. San Jose, CA (PRWEB) January 29, 2014 Edison DC Systems (EDCS), a Wisconsin based electrical engineering company, today exhibiting at the Open Compute Summit V booth C-20, is announcing its Virtual Ground Technology—a new architecture for safely and efficiently distributing multiple megawatts of direct current (DC) power to IT server equipment. “This...

Researchers Develop 'Spinning Trap' To Measure Electron Roundness
2013-12-05 19:47:47

National Institute of Standards and Technology (NIST) JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific understanding of the universe. As described in the Dec. 6, 2013, issue of Science, the JILA team used their new spinning method to make their first measurement of the electron's roundness—technically, the...

New Thermoelectronic Generator Converts Heat And Solar Energy Into Electricity
2013-12-03 16:09:29

American Institute of Physics Through a process known as thermionic conversion, heat energy -- such as light from the sun or heat from burned fossil fuels -- can be converted into electricity with very high efficiency. Because of its promise, researchers have been trying for more than half a century to develop a practical thermionic generator, with little luck. That luck may soon change, thanks to a new design -- dubbed a thermoelectronic generator -- described in AIP Publishing's Journal...

Novel LEDs Lead The Way To Cheaper Displays

University of Bonn Applications in smart phones or luminescent bathroom tiles conceivable / Collaboration of Bonn University, Regensburg University, the University of Utah and MIT OLEDs are already used in the displays of smart phones or digital cameras today. They offer an especially bright image with high contrast, but come with a serious drawback: typically, only one quarter of the electrical energy invested in running the device is actually converted into light. This ratio can be...

Article in 'AIP Advances' describes new topological insulator materials developed in China and US that may speed future semiconductor chips Imagine if the "information superhighway" had HOV lanes so that data could be stored, processed and disseminated many times faster than possible with today's electronics. Researchers in the United States and China have teamed to develop such a speedway for future devices, an exotic type of electrical conductor called a topological insulator (TI). In a...

Promising candidate for information processing with magnetic molecules Magnetic molecules are regarded as promising functional units for the future of information processing. An interdisciplinary team of researchers from Jülich and Aachen were the first to produce particularly robust magnetic molecules that enable a direct electrical readout of magnetic information. This was made possible by selecting the rare earth metal neodymium as the central building block of the molecule. The team's...

Quantum Dots Used To Generate Electricity From Waste Heat
2013-02-14 14:46:17

University of Rochester A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. "The system is really a simple one, which exploits certain properties of quantum dots to harvest heat," Professor Andrew Jordan of the University of Rochester said. "Despite this simplicity, the power it could generate is still larger than any other nanoengine that has been considered until now."...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
