Solution to two long-standing mysteries of cuprate superconductivity found. 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" phase, the movement of superconducting electrons appears to be restricted to certain directions. So exploring the pseudogap and whether and how it affects the movement of electrons has been a pivotal challenge. Now, a team lead by scientists at the U.S. SunShot Initiative.

Cascade solar concentrator greatly reduces solar cell footprint. (Phys.org) —Solar cells are often made of expensive materials, which is why much research is focused on finding cheaper materials in order to reduce the overall cost of solar energy.
Another way around this problem is to use solar concentrators—cheaper light-absorbing materials that cover a large area, which absorb, redirect and focus light onto a smaller area containing the actual solar cells. While the solar cells are still expensive, fewer of them are needed to generate a given amount of electricity because they receive more sunlight. In a new study published in Applied Physics Letters, Sthy Flores Daorta, et al., at the University of Pavia in Pavia, Italy, and the Eni Donegani Institute's Research Center for Non-Conventional Energies in Novara, Italy, have proposed and fabricated a new design for luminescent solar concentrators (LSCs). Soon Censored? Korean Scientists Successfully Kill Cancer with Magnets. In South Korea, scientists used a magnetic field to get cancer cells to actually self-destruct.
The body removes old, defective, and infected cells through the process of programmed cell death (PCD), or apoptosis. In apoptosis, the rejected cell responds to certain signals sent by the body by fragmenting. Immune cells then consume these fragments. The magnets help trigger apoptosis. When apoptosis fails, however, rejected cells divide uncontrollably, developing tumors. Magnets Induce Apoptosis. Solar Roadways installs energy harvesting parking lot. About 8 years ago, an electrical engineer and his counselor wife started throwing around an idea to replace asphalt on highways and byways throughout the US with electricity-producing solar panels that were tough enough to be driven upon.
The idea blossomed into a project, where the panels featured built-in LEDs that could “paint the road” with markings and warnings, and could be heated to prevent snow and ice build up. The US Federal Highway Administration paid for the couple to produce a working prototype, which they did, and then again to expand the concept into an operational parking lot setup. As the latter contract comes to an end, the Solar Roadways project has released photos of the (almost) completed installation at its Idaho electronics lab. Now the team is dipping into crowd-funding waters with a campaign to raise funds for the move into commercial production. Icists discover how to change the crystal structure of graphene. A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology.
Graphene consists of extremely thin sheets of graphite: when writing with a pencil, graphene sheets slough off the pencil's graphite core and stick to the page. If placed under a high-powered electron microscope, graphene reveals its sheet-like structure of cross-linked carbon atoms, resembling chicken wire. When manipulated by an electric field, parts of the material are transformed from behaving as a metal to behaving as a semiconductor, the UA physicists found. Graphene is the world's thinnest material, with 300,000 sheets needed to amount to the thickness of a human hair or a sheet of paper. Trilayer graphene can be stacked in two unique ways. Hawaii's Solar Market Is Booming; Why This Is a Very Bad Thing. In June 2001, when Hawaii became the 35th state to adopt a Net Energy Metering (NEM) law to promote the installation of small renewable energy grid-connected systems, it probably seemed like one of those “duh” moments.
All that sun power waiting to be harnessed would certainly transform the state into one blazing hot solar market. But things started out slowly. In a recent article for the Honolulu Civil Beat, Marco Mangelsdorf, who is president of ProVision Solar and also teaches energy politics at University of Hawaii at Hilo, noted that from 2001 through 2007 a total of only 386 NEM systems were installed across the state. Multilayer, microscale solar cells enable ultrahigh efficiency power generation. Researchers at the University of Illinois at Urbana-Champaign use a printing process to assemble tiny cells into multilayer stacks for extraordinary levels of photovoltaic conversion efficiency.
As an energy source, the Sun has always been a dependable provider. Although it freely shines on everyone, the ability to capture and convert the Sun's abundant energy is anything but free. However, new technologies aimed at achieving "full spectrum" operation in utility-scale photovoltaics may soon make solar energy a viable option. "A few simple ideas in materials science and device assembly allow us to bypass many of the limitations of traditional photovoltaic technologies," explained John Rogers, whose research group is developing these concepts. As a result of these new efficiencies, external industry experts project solar energy electricity generation costs that can reach, without subsidies, levels that are lower than coal, natural gas, and nuclear.
Now That Solar Capacity Is Soaring—Koch Brothers Demand Tax on the Sun. U.S.
Solar electric capacity has expanded explosively - 418% - from 2326 megawatts in 2010 to 12,057 MW in February 2014, an increase of 9,731 MW reports the U.S. Energy Information Agency. Solar has moved rapidly from a niche market to 1.13% of total U.S. capacity. To stop the rapid growth of solar, which is threatening to break Americans from the death grip of fossil fuels, the Koch Brothers are demanding to tax the sun. Soapstone: The soft rock with incredible heat properties! Some Soapstone History People have quarried soapstone for thousands of years.
Native Americans in eastern North America used the soft rock to make bowls, cooking slabs, smoking pipes and ornaments as early as the Late Archaic Period (3000 to 5000 years ago).  Native Americans on the west coast traveled in canoes from the mainland to San Clemente Island (60 miles offshore!) To obtain soapstone for cooking bowls and effigy carving as early as 8000 years ago.  The people of Scandinavia began using soapstone during the Stone Age and it helped them enter the Bronze Age when they discovered that it could be easily carved into molds for casting metal objects such as knife blades and spearheads.

Naked Energy touts hybrid solar panel in tube design. (Phys.org) -- A British company, Guildford-based Naked Energy, has come up with a “hybrid” solar panel that has generated much interest in the past weeks because of its design, function, and test results, comparing favorably to traditional solar panels. The solar panel is of the “hybrid” variety because it does two jobs at the same time. The product, called Virtu, can generate both electricity and hot water simultaneously.
The company believes that with Virtu they have invented the right design and process to achieve an effective thermal transfer system. The panel is in a vacuum tube configuration, The tubes have low thermal losses and will produce energy regardless of the climate they operate in, hot or cold, according to the company. “The annual yield depends on the application, local climatic conditions and quantity of panels installed. Naked Energy is prepared for more turning points. Zero point energy field effects photons. MostRecentIssue. Planarized Star-Shaped Oligothiophenes as a New Class of Organic Semiconductors for Heterojunction Solar Cells - de Bettignies - 2003 - Advanced Materials. Zamsolar. Quantum Efficiency. The "quantum efficiency" (Q.E.) is the ratio of the number of carriers collected by the solar cell to the number of photons of a given energy incident on the solar cell. The quantum efficiency may be given either as a function of wavelength or as energy.
If all photons of a certain wavelength are absorbed and the resulting minority carriers are collected, then the quantum efficiency at that particular wavelength is unity. The quantum efficiency for photons with energy below the band gap is zero. A quantum efficiency curve for an ideal solar cell is shown below. The quantum efficiency of a silicon solar cell. While quantum efficiency ideally has the square shape shown above, the quantum efficiency for most solar cells is reduced due to recombination effects. The "external" quantum efficiency of a silicon solar cell includes the effect of optical losses such as transmission and reflection. YouTube. AppDSolarRadiation. Solar Water Heaters.

How do i turn algae into fuel? - Physics Forums. The easiest and cheapest way is to use a centrifuge to separate the algae from the water, and then a press [like an olive press] to remove the oil from the algae.
There are many methods of extracting the oil from the algae, including the use of chemicals. If you go to you will find many links and good information. Once you have separated the oil from the algae, it is fairly straighforward to convert the oil to biodiesel through a chemical process known as transesterification. Arup unveils world's first algae-powered building. Eco-pods by Howeler + Yoon Architectureand Squared Design Lab. Boston architects Howeler + Yoon and Los Angeles digital designers Squared Design Lab have designed a conceptual structure for Boston, where an unfinished building would be covered in modular pods growing algae for biofuel. The pods would be continuously rearranged by robotic arms (powered by the micro-algae produced) to ensure the optimum growing conditions for alage in each pod. The designers intend to use the structure, called Eco-pods, to inform the public about the potential of micro-algae, a bio-fuel that can be grown vertically.
The pods could also house research projects. Personal Protective Equipment (PPE) Personal Protective Equipment (PPE) The earth's orbit. Bob Hardage: Using seismic technologies in oil and gas exploration. Seismic waves – the same tool used to study earthquakes – are frequently used to search for oil and natural gas deep below Earth’s surface. These waves of energy move through the Earth, just as sound waves move through the air. In oil and gas exploration, seismic waves are sent deep into the Earth and allowed to bounce back. Geophysicists record the waves to learn about oil and gas reservoirs located beneath Earth’s surface. 10 Green-Collar Jobs with $80,000+ Salaries.
