More Efficient Solar Panel Design

Written by , on May 12, 2009

Scientists from the Rensselaer Polytechnic Institute in New York have developed a new design for solar panels which dramatically increases their efficiency The solar panels have rows of miniature concentrator lenes with concententric grooves which track the sun’s movement and focus it on postage-stamp sized solar cells. Microchannels at the base of the module transfer […]  Read more »

Low-temperature Geothermal Plant Goes Online

Written by , on May 9, 2009

Raser Technologies has begun delivering 10 megawatts of clean electricity to Anaheim, California, from its first low-temperature, binary geothermal plant located in Beaver County, Utah.  The plant’s power source is underground brine which is at a temperature of just 126ºC  Geothermal plants typically need temperatures over 180ºC to operate effectively. In a binary cycle closed […]  Read more »

New Wave Power Technology Demonstrated

Written by , on May 9, 2009

A British company, Checkmate Seaenergy Ltd, has demonstrated a new wave energy device known as “Anaconda”.. Its inventors claim the key to its success lies in its simplicity: Anaconda is little more than a length of rubber tubing filled with water. Waves in the water create bulges which travel along the tubing gathering energy. In […]  Read more »

Bioelectricity More Efficient than Bioethanol

Written by , on May 8, 2009

Researchers writing in the journal Science say that converting biomass to electricity which is used to power electric cars is far more efficient than growing plants to make bioethanol for fuel for cars. They calculate that, compared to ethanol used for internal combustion engines, bioelectricity used for battery-powered vehicles would deliver an average of 80% […]  Read more »
