Biosolar breakthrough promises cheap, easy green electricity

Thu, 02 Feb 2012 09:22:22 EST
Scientists are turning the term "power plant" on its head. A team of researchers has developed a system that taps into photosynthetic processes to produce efficient and inexpensive energy.

New tool determines value of solar photovoltaic power systems

Wed, 01 Feb 2012 09:49:49 EST
Consistent appraisals of real estate outfitted with photovoltaic installations are a challenge for the nation's real estate industry, but a new tool addresses that issue.

Classifying solar eruptions

Wed, 25 Jan 2012 09:38:38 EST
Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). While these are the most common solar events, the sun can also emit streams of very fast protons -- known as solar energetic particle (SEP) events -- and disturbances in the solar wind known as corotating interaction regions (CIRs). All of these can produce a variety of "storms" on Earth that can -- if strong enough -- interfere with short wave radio communications, GPS signals, and Earth's power grid, among other things.

New material to remove radioactive gas from spent nuclear fuel

Tue, 24 Jan 2012 14:03:03 EST
Research by chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste. They have used metal-organic frameworks to capture and remove volatile radioactive gas from spent nuclear fuel.

Power generation is blowing in the wind

Tue, 17 Jan 2012 16:16:16 EST
By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time. Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes (such as turbulence) to the wind profile, a turbine will produce different amounts of power. This variable power can be predicted by looking at atmospheric stability, according to new research.
