Ground-source heat pumps take advantage of stable temperatures just below the Earth's crust for energy-efficient heating and cooling.

August 30, 2007

Ground-source heat pumps (GSHPs), often called “geothermal heat pumps,” exploit the relatively stable temperatures found just 5 feet (1.5 m) or more below the surface, either depositing or extracting low-intensity heat. Heat pumps—whether ground-source or air-source—are basically air conditioners that can be run in reverse to provide heating as... Read more

Light-emitting diodes (LEDs) use semi-conducting materials to turn electricity into light; electrons jump from one material to another, emitting photons as they travel. Different semiconductor materials create different colors of light: most white LEDs use indium gallium nitride (InGaN), which actually emits blue light. The blue light excites a... Read more
