Device measures conductivity and velocity of ionized gas streams

Coaxial arrangement of primary coil and two sensing secondary coils contained inside slender quartz tube inserted into ionized stream permits simultaneous determination of conductivity and linear velocity. System results agree favorably with theory

Groundwater Heat Pump: An Efficient Way to Heat and Cool Your Home

Engineers at the Utah Water Research Laboratory and the Mechanical Engineering Department at Utah State University have looked into the evonomic feasibility of groundwater heat pumps for residential heating and cooling in the Utah climate. They have found that this type of system conserves evergy and may cost less than conventional heating systems. By using a heat pump, thermal energy can be taken from goundwater and can be used to heat homes in the winder and cool them in the summer. If you are a Utah homeowner in an area where the goundwater heat pump system is economical, you may wish to take advantage of groundwater as an abundant (and often overlooked) indirect source of solar energy
