NEXT MEETING June 12 - "Georgia State University's CHARA Array at Historic Mount Wilson Observatory" - Dr. Harold A. McAlister, Georgia State University

The CHARA Array is the world's most powerful facility for high resolution studies of stars. The design and operation of the Center for High Angular Resolution Astronomy (CHARA) Array will be described by Dr. Harold McAlister, Regents' Professor of Astronomy and Director of CHARA at Georgia State University. Dr. McAlister will also share some of the first scientific results that have come from this facility that became routinely operation in early 2005. These results include measuring the sizes, shapes, distances, temperatures and masses of stars as well as calibrating the fundamental distance scale of the Universe. The telescope array is located in the San Gabriel Mountains of southern California on the grounds of the famous Mt. Wilson Observatory. If you are an astronomy fan, don't miss this exciting presentation by a returning UTC graduate! Addtional background at www.chara.gsu.edu/CHARA and www.mtwilson.edu.

PREVIOUS MEETING June 5, 2006 - "Geothermal Heat Pump Systems in the Tennessee Valley" - David Dinse, Tennessee Valley Authority

David Dinse made a fine presentation on the conceptual basics, challenges, economics, and practical hands-on experiences of geothermal heat pump systems. Geothermal heat pumps have the lowest life-cycle cost and the lowest impact on our environment. Consumers rank comfort and satisfaction with geoexchange systems higher than all others. While a higher initial investment is required, the investment is paid back through low energy bills (enhancing resale value), excellent family safety, and real comfort. (www.geoexchange.org)
