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.

Years-old, off-the-shelf technology uses compressed air to drive old-fashioned car engine pistons instead of combusting gas or diesel fuel to create a burst of air to do the same thing. On highways, the CAV can cruise at interstate speeds for nearly 800 miles with a small motor that compresses outside air to keep the tank filled. The motor isn't finicky about fuel. It will burn gasoline or diesel as well as biodiesel, ethanol or vegetable oil. Even if it used only regular gasoline, the air car would average 106 mpg, more than double today's fuel sipping champ, the Toyota Prius. The air tank also can be refilled when it's not in use by being plugged into a wall socket and recharged with electricity as the motor compresses air. More info here.

PV-Thermal hybrids have recently become popular because these systems make more effective use of valuable solar roof space. The Hybrid collector effectively more than doubles the per square foot power output of PV alone. This is done by producing heat for hot water or space heating as a byproduct, in effect, a solar co-generation process. On its own, Solar Thermal usually produces over 4 times the energy of PV in thermal terms. A thermal collector covered with PV is going to work at lower efficiency because most of the direct sunlight is blocked by the cells. If the thermal portion of the Hybrid collector was working at only 25% efficiency, the gross energy output would be doubled. Now add to that increased PV panel efficiency and decreased cooling load and you have a real winning combination. Read more about this idea.
The global solar energy market in 2008 is expected to grow by 50% compared to 2007. The Chinese solar PV industry is growing rapidly and will soon be the biggest producer of solar cells and modules in the world.

For homeowners interested in reducing their personal carbon footprint through solar power but wanting to start off on a smaller scale than a whole-house option, an exciting, energy-saving solution will be available soon from heating and air conditioning leader Lennox Industries. Expected to be available in 2009, Lennox' new SunSource™ system is the industry's first integrated, solar-assisted residential heating and cooling system - and it uses just a single 190-watt solar panel. Featuring a patent-pending design, the innovative system is currently in full operation at multiple test sites throughout the country. The single 190-watt solar panel provides power to assist the fan motor that moves air across the outdoor coil, a key part of any home comfort system. Read more.

In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
