Solar power without solar cells: A hidden magnetic effect of light could make it possible

Solar power without solar cells: A hidden magnetic effect of light could make it possible
A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. The researchers found a way to make an "optical battery," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. In the process, they overturned a century-old tenet of physics. "You could stare at the equations of motion all day and you will not see this possibility. Light has electric and magnetic components. "This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation," Rand said. What makes this possible is a previously undetected brand of "optical rectification," says William Fisher, a doctoral student in applied physics. Rand and Fisher found that under the right circumstances and in other types of materials, the light's magnetic field can also create optical rectification.

Sator Square The earliest datable square was found in the ruins of Pompeii which was buried in the ash of Mt. Vesuvius in 79 AD. Examples may be carved on stone tablets, or engraved into clay before firing as pottery. Translation[edit] Sator (from sero=to sow) Sower, planter; founder, progenitor (usually divine); originator Arepo unknown, likely an invented proper name; its similarity with arrepo, from ad repo, 'I creep towards', may be coincidental Tenet (from teneo=to hold) holds, keeps; comprehends; possesses; masters; preserves Opera (a) work, care; aid, service, (an) effort/trouble Rotas (rota) wheel, rotate; (roto) (I) whirl around, revolve rotate; used in the Vulgate Psalms as a synonym for whirlwind and in Ezekiel as plain old wheels. One likely translation is "The farmer Arepo has [as] works wheels [a plough]"; that is, the farmer uses his plough as his form of work.

(3) Given our current technology and with the proper training, would it be possible for someone to become Batman Lights and flat-panel displays: Researchers 'brighten' the future of organic light-emitting diode technology Chlorine is an abundant and readily available halogen gas commonly associated with the sanitation of swimming pools and drinking water. Could a one-atom thick sheet of this element revolutionize the next generation of flat-panel displays and lighting technology? In the case of Organic Light-Emitting Diode (OLED) devices, it most certainly can. Primary researchers Michael G. Helander (PhD Candidate and Vanier Canada Graduate Scholar), Zhibin Wang (PhD Candidate), and led by Professor Zheng-Hong Lu of the Department of Materials Science & Engineering at the University of Toronto, have found a simple method of using chlorine to drastically reduce traditional OLED device complexity and dramatically improve its efficiency all at the same time. "It turns out that it's remarkably easy to engineer this one-atom thick layer of chlorine onto the surface of ITO," says Helander.

Sacred Geometry: Deciphering the Code untitled by J. Curt Stager This article is an adaptation of the introduction to J. Curt Stager’s Deep Future: The Next 100,000 Years of Life on Earth (Thomas Dunne Books, an imprint of St. This excerpt appears in two parts. In the past, seemingly intractable debates over environmental issues have sometimes been resolved with the aid of long-term historical perspectives. Although it's a rather eclectic discipline that straddles the fields of geology and biology, my chosen profession of paleoecology is well known among scientists for its ability to harness truly long-term thinking in order to place current environmental issues into their most meaningful contexts, showing us where we've been, how we got here, and where we're likely to be headed next. Today, scientists with such long-term perspectives are once again nudging us beyond currently entrenched arguments over human-driven climate change, but their gaze is aimed forward in time, as well as backward. But all is not doom and gloom.

Physicists create clouds of impenetrable gases that bounce off each other When one cloud of gas meets another, they normally pass right through each other. But now, MIT physicists have created clouds of ultracold gases that bounce off each other like bowling balls, even though they are a million times thinner than air -- the first time that such impenetrable gases have been observed. While this experiment involved clouds of lithium atoms, cooled to near absolute zero, the findings could also help explain the behavior of similar systems such as neutron stars, high-temperature superconductors, and quark-gluon plasma, the hot soup of elementary particles that formed immediately after the Big Bang. A paper describing the work will appear in the April 14 issue of Nature. The researchers, led by MIT assistant professor of physics Martin Zwierlein, carried out their experiment with an isotope of lithium that belongs to a class of particles called fermions. Different states of fermionic matter are distinguished by their mobility.

High-temperature superconductor spills secret: A new phase of matter? Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature. "Our findings point to management and control of this other phase as the correct path toward optimizing these novel superconductors for energy applications, as well as searching for new superconductors," said Zhi-Xun Shen of the Stanford Institute for Materials and Energy Science (SIMES), a joint institute of the Department of Energy's SLAC National Accelerator Laboratory and Stanford University. Shen led the team of researchers that made the discovery; their findings appear in the March 25 issue of Science. The electrons in the pseudogap state aren't superconducting -- so what are they doing?

Scientists extract images directly from brain ::: Pink Tentacle Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. For now, the system is only able to reproduce simple black-and-white images. "These results are a breakthrough in terms of understanding brain activity," says Dr.

This Geoid Is The Most Sophisticated Map Of Earth's Gravity Yet Since 2009 the European Space Agency's Gravity field and steady-state Ocean Circulation Explorer (GOCE) has been mapping the Earth's gravitational field, and today the agency released its most detailed model of the geoid to date. More potato-shaped than spherical, this latest model shows just how different gravity can be at different points on our planet. The geoid is, roughly speaking, a model of the earth that doesn't follow the surface of the crust but rather the average ocean surface if the oceans were at equilibrium and extended through the continents--in other words, the shape the earth would take based on its existing gravitational field if the tides, currents, and crust features didn't distort things. It's an idea that's been around for well more than a century but only recently has been modeled precisely, largely thanks to GOCE. Today's new geoid marks the most precise model to date.

NEW MOON: SACRED REALITY « Critical Trilogy Pisces New Moon; March 14, 2010 5:01 PM It was quite a synchronicity to open Orca Chantress Beluga Shaman by Leesa Sklover, a Jungian practitioner and enchanting chanteuse whom I heard speak at the Temenos Institute in Westport on Friday night. She played the Orca Chantress kundalini yoga chant at the close of her presentation,”A Jungian Look at Yoga Therapy, Meditation and Chant.” The music hits at my highest and lowest chakras simultaneously. She certainly has the sacred geometry down! This afternoon, after nearly 48 hours of a power outage, which made the darkest moon last night I have had in a long while, I open the CD and discover a song, Beautiful All Around, containing the sacred geometry of the hieros gamos! It is the New Moon, after all, and the discovery brings to mind an alchemical image depicting the geometry of the six directions: The King (Sol) and Queen (Luna) united by the dove (spirit) This chant contains the YOD, the last letter of the Hebrew alphabet sky: yod hey vav

Blue Brain Project Earth Has an Orbital Companion Stuck in a Horseshoe-Shaped Orbit Around the Sun Near-Earth asteroids aren't all that rare, but today two researchers at Armagh Observatory in Northern Ireland say they've found an extremely rare near-Earth object in an orbit very similar to Earth's. Asteroid 2010 SO16 is not exotic because of it's closeness to the home planet, but because it is stuck in a rare horseshoe orbit. Horseshoe orbits only happen under a specific set of circumstances, so it is believed they are pretty rare. The name "horseshoe" is derived from the shape of the object's orbit as seen from Earth--that is, it doesn't stop mid-orbit, turn around, and travel in the other direction. It has everything to do with shifts in the object's orbital path and our perspective of the object as it gets closer, shifts orbit, and then gets further away without ever passing Earth. To better understand this, one only needs to keep in mind that objects closer to the sun orbit faster and objects further away orbit more slowly. The full paper is here (PDF). [Technology Review]
