  3. Studies See Significant Drop in Rooftop, Utility-scale Solar Prices

    The price of solar energy in the U.S. continues to fall substantially, according to the latest editions of two annual reports produced by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).,br />
    A third Berkeley Lab report, written in collaboration with researchers at Yale Univ., the Univ. of Texas at Austin and the U.S. Department of Energy (DOE), shows that local permitting and other regulatory procedures can significantly impact residential photovoltaic (PV) prices.

  5. Light Source for Chips Can Be TunedChips that use light, rather than electricity, to move data would consume much less power — and energy efficiency is a growing concern as chips’ transistor counts rise. Of the three chief components of optical circuits — light emitters, modulators and detectors — emitters are the toughest to build. One promising light source for optical chips is molybdenum disulfide (MoS2), which has excellent optical properties when deposited as a single, atom-thick layer. Other experimental on-chip light emitters have more-complex three-dimensional geometries and use rarer materials, which would make them more difficult and costly to manufacture.In the next issue of the journal Nano Letters, researchers from MIT’s departments of Physics and of Electrical Engineering and Computer Science will describe a new technique for building MoS2 light emitters tuned to different frequencies, an essential requirement for optoelectronic chips. Since thin films of material can also be patterned onto sheets of plastic, the same work could point toward thin, flexible, bright, color displays.Read more: http://www.laboratoryequipment.com/news/2014/09/light-source-chips-can-be-tuned

  11. Nanotech Cools Electrons Without External SourcesA team of researchers has discovered a way to cool electrons to -228 C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy. The process involves passing electrons through a quantum well to cool them and keep them from heating. The team details their research in a paper in Nature Communications.“We are the first to effectively cool electrons at room temperature. Researchers have done electron cooling before, but only when the entire device is immersed into an extremely cold cooling bath,” said Seong Jin Koh, an associate professor at UT Arlington in the Materials Science & Engineering Department, who has led the research. “Obtaining cold electrons at room temperature has enormous technical benefits. For example, the requirement of using liquid helium or liquid nitrogen for cooling electrons in various electron systems can be lifted.”Read more: http://www.laboratoryequipment.com/news/2014/09/nanotech-cools-electrons-without-external-sources

  15. China’s Energy Plan Holds Climate RisksDeep in the hilly grasslands of remote Inner Mongolia, twin smoke stacks rise more than 200 feet into the sky, their steam and sulfur billowing over herds of sheep and cattle. Both day and night, the rumble of this power plant echoes across the ancient steppe, and its acrid stench travels dozens of miles away.This is the first of more than 60 coal-to-gas plants China wants to build, mostly in remote parts of the country where ethnic minorities have farmed and herded for centuries. Fired up in December, the multibillion-dollar plant bombards millions of tons of coal with water and heat to produce methane, which is piped to Beijing to generate electricity.It’s part of a controversial energy revolution China hopes will help it churn out desperately needed natural gas and electricity while cleaning up the toxic skies above the country’s eastern cities. However, the plants will also release vast amounts of heat-trapping carbon dioxide, even as the world struggles to curb greenhouse gas emissions and stave off global warming.Read more: http://www.laboratoryequipment.com/news/2014/08/chinas-energy-plan-holds-climate-risks

  17. Photosynthesis Inspires Better FuelsSociety’s energy supply problems could be solved in the future using a model adopted from nature. During photosynthesis, plants, algae and some species of bacteria produce sugars and other energy-rich substances (i.e. fuels) using solar energy. A team headed by researchers from the Max Planck Institute for Chemical Energy Conversion is currently developing experimental methods to ascertain how this process occur in nature.The scientists are investigating a particularly important cofactor involved in photosysthesis, a manganese-calcium complex, which uses solar energy to split water into molecular oxygen. They have determined the exact structure of this complex at a crucial stage in this chemical reaction. This has led to a detailed suggestion as to how molecular oxygen, O2, is formed at this metal complex.

  19. Meeting of Rivers, Seas May Be Source of PowerWhere the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT.The researchers evaluated an emerging method of power generation, called pressure retarded osmosis (PRO), in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less-salty stream would cross the membrane to a pre-pressurized saltier side, creating a flow that can be sent through a turbine to recover power.Read more: http://www.laboratoryequipment.com/news/2014/08/meeting-rivers-seas-may-be-source-power
