Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input is lost as waste heat. The material could signify a paradigm shift. The inefficiency of current thermoelectric materials has limited their commercial use. Now, with a very environmentally stable material that is expected to convert 15 to 20 percent of waste heat to useful...

Death Valley Still The Hottest Spot On Earth
2012-09-13 13:39:03

Lee Rannals for redOrbit.com - Your Universe Online Meteorologists have ended an 80-year debate over where and what the hottest temperature ever recorded on Earth was. Back in the summer of 1913, temperatures soared to a scorching 134 degrees Fahrenheit in Death Valley, California, setting a record as the world's hottest temperature. However, less than 10 years later, on September 13, 1922, reports came in of a 136.6 degree Fahrenheit temperature being recorded in El Azizia, Libya....

Steve K´s vaping world releases a new review of Innokin iTaste VV e cigarette performance. (PRWEB) June 22, 2012 The Innokin iTaste VV (version 2) tries to turn what Vapers knows about e cigarettes on their ears. The device features a unique square design, variable voltage and an innovative magnetic connector. It works best in its original, proprietary configuration, but the addition of adapters means it will work with most standard cartomizers. From those who haven´t made the...

Scientist works to understand how fluctuations change biochemical reactions inside us We are surrounded by a constantly changing magnetic field, be it the Earth's or those emanating from devices, such as cell phones. Carlos Martino, an assistant professor at the University of Nevada, Reno, is interested in understanding how these magnetic-field fluctuations change biochemical reactions inside us. Martino explains that the subject is controversial. "Our research shows that exposure to...

Concordia physicists modify battery-like enzyme to produce carbon-neutral energy New research at Concordia University is bringing us one step closer to clean energy. It is possible to extend the length of time a battery-like enzyme can store energy from seconds to hours, a study published in the Journal of The American Chemical Society shows. Concordia Associate Professor László Kálmán – along with his colleagues in the...

Magnetic Fields Can Send Particles To Infinity
2012-04-17 13:34:38

Researchers from the Complutense University of Madrid (UCM, Spain) have mathematically shown that particles charged in a magnetic field can escape into infinity without ever stopping. One of the conditions is that the field is generated by current loops situated on the same plane. At the moment this is a theoretical mathematical study, but two researchers from UCM have recently proved that, in certain conditions, magnetic fields can send particles to infinity, according to the study...

Helmholtz-Zentrum Berlin developed a magnetic valve that novel electronic devices can be realistic In close collaboration with colleagues from Bochum and the Netherlands, researchers from the Helmholtz-Zentrum Berlin (HZB) have developed a novel, extremely-thin structure made of various magnetic materials. It is suitable as a kind of magnetic valve for data-storage units of the most recent generation and makes use of effects in the context of so-called spintronics, with which, in addition...
