Reports the impact of air cooling technologies on the International Gas Turbine Institute Turbo Expo in New Orleans, Louisiana. Power consumption of turbine air cooling systems; Types of evaporative cooling media developed by Munters Corp., Operation of cogeneration plant by Kalaeloa Partners.

Reports on United States-based energy companies and utilities' adaption of district cooling. Background on district cooling technology; Advantages of using the technology; Reasons for the growth of district cooling in the US; Industry analysts' comments.

The article informs that a group of energy consultants in the U.S. have looked into the feasibility of cooling building space by combining a solar collector with an absorption chiller. Instead of converting the solar flux into electricity, the system will use the sun's energy to heat the absorption chiller. The consultants say that a solar-thermal absorption chiller may make economic sense for commercial installations at least in some parts of the country.

Reports the effectiveness of an onboard fuel-distilling system to restrain the hydrocarbon spills from a cool starting engine in Texas. Reasons for the exhaustion of unwanted hydrocarbons; Key elements of the fuel-distilling system; Use of a volatile fuel to limit the release of hydrocarbon emissions.

Reports on the development of solid-state lasers by scientists at the Los Alamos National Laboratory in New Mexico that will cool satellite-borne detectors and instruments. Absorbing of energy from microscopic thermal vibrations; Chilling objects by bright light; Tuning the laser to outsmart the normal tendency to produce heat; Shining a beam of infrared light nearly as intense as the sun's surface.

Describes a computer model developed by scientists at the University of California's Lawrence Berkeley Laboratory that simulates the circulation of water through ceilings or floors to cool buildings. Flow of water through plastic tubes; Removal of thermal energy; Advantaged of hydronic radiant systems.
