Xantrex Technology Inc., a subsidiary of Schneider Electric, announces it was awarded contracts from enXco Inc., an EDF Energies Nouvelles Company, valued at approximately US$1.5 million.
Nuclear power plants smaller than a garden shed and able to power 20,000 homes will be on sale within five years, say scientists at Los Alamos, the US government laboratory which developed the first atomic bomb. The miniature reactors will be factory-sealed, contain no weapons-grade material, have no moving parts and will be nearly impossible to steal because they will be encased in concrete and buried underground. The goal is to generate electricity for 10 cents a watt anywhere in the world. The reactors, only a few metres in diameter, will be delivered on the back of a lorry to be buried underground. They must be refuelled every 7 to 10 years. Read More Here.
Zenergy has successfully completed testing of its first commercial HTS Fault Current Limiter, which is expected to be installed in the commercial electricity grid of Southern California Edison in Q1 2009. Zenergy's FCL represents its second groundbreaking commercial product based on HTS technology.
A new fiber-optic laser system can measure wind speed and direction up to 1000 meters in front of a wind turbine, giving the massive machines enough precious seconds to proactively adapt to gusts and sudden changes in wind direction. The device, developed by Catch the Wind, a startup based in Manassas, VA, could improve the efficiency of wind turbines and keep them from breaking down. A prototype of the new laser-based LIDAR system, shown here, can horizontally project three invisible laser beams up to 300 meters in front of a wind turbine. Small particles in the wind are detected as they cross the beams. Catch the Wind claims that its laser system can boost turbine power output by 10 percent by improving orientation accuracy. The pitch of the blades can also be adjusted in advance of the wind to reduce wear and tear on turbine gearbox components and blades, lowering repair and maintenance costs by up to 10 percent and extending the operating life of a wind farm, the company says.

RainTube wins recognition in Re:Construct competition as a potential design element in Re:Vision's prototype sustainable urban space
Scientists from the Australian National University (ANU), Tianjin University in China and Chromasun, a Silicon Valley company with strong Australian connections, will join forces to create roof-mounted solar trough concentrator systems that they believe will be more cost-effective and efficient than previous models. The prototype measures 1.7 x 1.5 x 0.2 meters and incorporates seven mirrors that focus sunlight onto receiver tubes. Crystalline Si micro PV cells - with an efficiency of about 20% under concentrated sunlight - will be fitted to the receivers to operate under concentrated x20 - x30 sunlight with water cooling being used to deliver heat to the hot-water tank.

RNCOS has recently added a new Market Research Report titled, “Wind Power: Opportunities in Emerging Markets” to its report gallery. The report provides a brief description on key turbine manufacturing companies present in the emerging economies.
Current solar panels -- which convert energy from the sun into electricity -- absorb only about two-thirds of available sunlight. But surfaces treated with a coating developed at Rensselaer Polytechnic Institute in Troy, New York, can harvest 96.2 percent of sunlight. An untreated silicon solar cell only absorbs 67.4 percent of sunlight shone upon it - meaning that nearly one-third of that sunlight is reflected away and thus unharvestable. From an economic and efficiency perspective, this unharvested light is wasted potential and a major barrier hampering the proliferation and widespread adoption of solar power. Read more here.
