Billions of dollars lost each year as waste heat from industrial processes can be converted into electricity with a technology being developed at the Department of Energy's Oak Ridge National Laboratory. The high-efficiency thermal waste heat energy converter actively cools electronic devices, photovoltaic cells, computers and large waste heat-producing systems while generating electricity, according to Scott Hunter, who leads the development team. The potential for energy savings is...

"I have a slide that has a photo of a cornfield and a big photovoltaic array," says Robert Blankenship, a scientist who studies photosynthesis at Washington University in St. Louis. "When I give talks I often ask the audience which one is more efficient. Invariably the audience votes overwhelmingly in favor of photosynthesis. " They are wrong. This question and its surprising answer (below) is the point of departure for a provocative article published in the May 13 issue of Science. The...

Fungi play significant ecological and economic roles. They can break down organic matter, cause devastating agricultural blights, enter into symbiotic relationships to protect and nourish plants, or offer a tasty repast. For industrial applications, fungi provide a source of enzymes to catalyze such processes as generating biofuels from plant biomass. One large fungal group with such enzymes are the rust plant pathogens which cannot survive on their own so they use crops as hosts, leading to...

Novel properties of ferroelectric materials discovered at the Department of Energy's Oak Ridge National Laboratory are moving scientists one step closer to realizing a new paradigm of electronic memory storage. A new study led by ORNL's Peter Maksymovych and published in the American Chemical Society's Nano Letters revealed that contrary to previous assumptions, domain walls in ferroelectric materials act as dynamic conductors instead of static ones. Domain walls, the separation zones only a...

The Department of Energy announced on Wednesday that it would invest up to $130 million for projects in its Advanced Research Projects Agency-Energy, or ARPA-E. The funding, which came in part from this month's federal budget deal, will go to five new program areas: producing biofuels as an alternative to oil, finding viable alternatives to rare-earth minerals, storing thermal energy, maintaining electric grid reliability and reducing solar power costs, the Department of Energy said. "ARPA-E...

In tests of four different types of new refrigerators, National Institute of Standards and Technology (NIST) researchers found that ice makers increased rated energy consumption by 12 to 20 percent. About three-fourths of that additional energy cost is due to the electric heaters used to release the ice bits from the molds. With only one-fourth of the extra energy actually used to cool and freeze water, "there are substantial opportunities for efficiency improvements merely by optimizing the...

New electrolyte mix increases energy storage by 70 percent Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. But new research indicates that modifying the battery's electrolyte solution significantly improves its performance. So much so that the upgraded battery could improve the electric grid's reliability and help connect more wind turbines and...

ASSR could reduce amount of heat needed in purification process Natural gas extracted from the nation's coal beds and methane-rich geologic features must first be purged of hydrogen sulfide before it can be used as fuel. Until now, processing methods have often proved to be inefficient, requiring large amounts of heat. But a team of Battelle researchers at the Department of Energy's Pacific Northwest National Laboratory has discovered a method that could dramatically cut the amount of heat...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
