After a mammoth tornado wiped out most of this rural Kansas community in 2007, supporters of clean energy in the state seized on an unusual opportunity to rebuild a town from the ground up with the latest green technology. They came up with a sustainable-power dreamscape: wind turbines to power hundreds of homes, futuristic buildings […]

These wind turbines will blow you away
Michael Jordan used to say that talent won games but teamwork and intelligence won championships. He had the Chicago Bulls in mind, but he could have been talking about wind turbines. When wind turbines harness breeze, they let out an uneven wake on the other side. This wake makes it hard for the turbines that […]
Discovery offers new possibilities for clean energy research
UH researchers find new high-efficiency thermoelectric material University of Houston physicists have discovered a new thermoelectric material offering high performance at temperatures ranging from room temperature up to 300 degrees Celsius, or about 573 degrees Fahrenheit. “This new material is better than the traditional material, Bismuth telluride, and can be used for waste heat conversion […]
Tornado-Stricken Town Rebuilds with Clean Energy
After a mammoth tornado wiped out most of this rural Kansas community in 2007, supporters of clean energy in the state seized on an unusual opportunity to rebuild a town from the ground up with the latest green technology. They came up with a sustainable-power dreamscape: wind turbines to power hundreds of homes, futuristic buildings […]
Meeting New Energy Star Energy Efficiency Ratings
In a typical supermarket, refrigeration alone accounts for over 35% of the energy consumed. It has become the object of increasingly stringent legislation targeting the vast energy saving potential of commercial refrigerators and freezers. Energy Star, the international standard for energy efficiency in consumer products, has mandated that by 2014, refrigerators must use 25% less […]

GE Offer for Alstom Not Good Enough
French President Francois Hollande says that an offer by General Electric Co. for troubled French engineering company Alstom is not good enough and wants the U.S. company to come up with a better deal. The $17 billion bid for Alstom’s energy activities has prompted resistance within the French government, which is struggling to revive the […]

Taking the Lead Out of a Promising Solar Cell
Environmentally friendly solar cell pushes forward the ‘next big thing in photovoltaics’ Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using “bench” chemistry — no fancy […]
Paper Examines Clues for Superconductivity in an Iron-Based Material
For the first time, scientists have a clearer understanding of how to control the appearance of a superconducting phase in a material, adding crucial fundamental knowledge and perhaps setting the stage for advances in the field of superconductivity. The paper, published in Physical Review Letters, focuses on a calcium-iron-arsenide single crystal, which has structural, thermodynamic […]
