PHYSorg.com: Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy's Ames Laboratory. A team of researchers at the Lab that is jointly funded by the DOE Office of Basic Energy Sciences, Division of Materials Sciences and Engineering and the Defense Advanced Research Projects Agency, achieved a 25 percent improvement in the ability of a key material to convert heat into electrical energy.
"What happened here has not happened anywhere else," said Evgenii Levin,
associate scientist at Ames Laboratory and co-principal investigator on
the effort, speaking of the significant boost in efficiency documented
by the research. Along with Levin, the Ames Lab-based team included:
Bruce Cook, scientist and co-principal investigator; Joel Harringa,
assistant scientist II; Sergey Bud'ko, scientist; and Klaus
Schmidt-Rohr, faculty scientist. Also taking part in the research was
Rama Venkatasubramanian, who is director of the Center for Solid State
Energetics at RTI International, located in North Carolina...
