Story tips from the Department of Energy's Oak Ridge National Laboratory, September 2008

cts expected to set new standards for performance and reliability. Capstone Turbine Corp. of California credits ORNL and the High Temperature Materials Laboratory for playing a key role in developing the C200 microturbine with a generating capacity of 200 kilowatts. The unit features 33 percent efficiency and meets stringent California emissions requirements. While most of the microturbines sold by Capstone are used in land-based distributed generation applications, the company is focusing on microturbines to be used in hybrid buses with double the fuel economy of a traditional diesel bus. This research has been funded by the Department of Energy's Advanced Microturbines Program. Capstone worked with ORNL through the HTML User Program.

GEOLOGY-- Compelling evidence . . .

Fragments of tektites, natural glass objects, discovered by a team of geologists and geochemists help support a theory that a meteorite may be responsible for the sudden climate change that devastated large mammals in North America 11,000 years ago. While critics of such an extraterrestrial event have in the past noted the lack of evidence, the micro-tektites from the Clovis-age Murray Springs in Arizona could cause them to rethink their position. "These micro-tektites contain iron oxide spherules in a glassy iron-silica or silica matrix, which is one indicator of a possible meteorite impact," said lead author Mostafa Fayek of the University of Manitoba in Winnipeg. "The spherules also contain elevated concentrations of vanadium and sulfur, and small amounts of titanium." The University of Tennessee's Larry Anovitz, who works in ORNL's Measurement Science and Systems Engineering Division, noted that the chemistry of the spherules and matrix is consistent with that of tektites associated with other meteorite impact sites such as those found in Romania. Funding was provided in part by
