Yale Engineers Making Solar Power More Efficient

Innovations by a team of Yale University researchers could lead to improvements in basic solar power technology that result in lower-cost, higher-efficiency photovoltaic systems.

Photovoltaics (PV) directly convert sunlight into electricity. PV systems can be arrayed on rooftops to generate electricity for entire buildings, among other uses. Less expensive, more efficient systems could encourage broader use of this clean energy technology. (more…)

Researchers Use New Approach to Overcome Key Hurdle for Next-Generation Superconductors

Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications – and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO).

A superconductor is a material that can carry electricity without any loss – none of the energy is dissipated as heat, for example. Superconductive materials are currently used in medical MRI technology, and are expected to play a prominent role in emerging power technologies, such as energy storage or high-efficiency wind turbines.

Microbes Generate Electricity While Cleaning Up Nuclear Waste

EAST LANSING, Mich. — Researchers at Michigan State University have unraveled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals.

Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. The implications could eventually benefit sites forever changed by nuclear contamination, said Gemma Reguera, MSU microbiologist. (more…)

Berkeley Scientists Pioneer Nanoscale Nuclear Materials Testing Capability

Nuclear power is a major component of our nation’s long-term clean-energy future, but the technology has come under increased scrutiny in the wake of Japan’s recent Fukushima disaster. Indeed, many nations have called for checks and “stress tests” to ensure nuclear plants are operating safely.

In the United States, about 20 percent of our electricity and almost 70 percent of the electricity from emission-free sources, including renewable technologies and hydroelectric power plants, is supplied by nuclear power. Along with power generation, many of the world’s nuclear facilities are used for research, materials testing, or the production of radioisotopes for the medical industry. The service life of structural and functional material components in these facilities is therefore crucial for ensuring reliable operation and safety. (more…)

Russian Nuclear Industry to Conquer Country of Pyramids

Russia is ready to build a nuclear power plant in Egypt at its own expense, to manage the plant, and even find markets for the electricity. Early next year Egypt is expected to announce a tender for the construction of nuclear power plant with the capacity of 1 GW 150 km from Alexandria. Russia’s Rosatom will participate in the tender.

A meeting of Russian-Egyptian intergovernmental commission on trade, economic and scientific-technical cooperation was held on Monday. From the Russian side it was chaired by the Minister of Industry and Trade Viktor Khristenko. (more…)

Roller Coaster Superconductivity Discovered

Washington, D.C.— Superconductors are more than 150 times more efficient at carrying electricity than copper wires. However, to attain the superconducting state, these materials have to be cooled below an extremely low, so-called transition temperature, at which point normal electrical resistance disappears. Developing superconductors with higher transition temperatures is one of physics’ greatest quests.

Between the Nightmare of the Gulf and the Magic of Solar Impulse

While the BP Deepwater Horizon well spits tens of thousands of barrels of oil offshore on the Gulf of Mexico, an environmental disaster of proportions never before imagined, a beautiful new kind of bird flies silently in the skies on its first test flight.
