Reverse Circulation (RC) Drilling Technique
Reverse circulation (RC) drilling uses a dual-walled drill pipe (rod) with a solid drill bit to produce a hole in a formation and delivers rock chips (cuttings) to the surface for a subsequent analysis. The drilling mechanism is a pneumatic reciprocating piston (hammer) driving a tungsten-steel drill bit and a compressor to blow the cuttings, created by the drilling operation, to the surface. Reverse... (posted by Alexander 2 years 319 days ago.)

Geothermal Drilling for Green Energy
Geothermal Heat Pumps (Ground-Source Heat Pumps) are electrically powered heating and cooling systems which transfer heat to and from the earth via a refrigeration process. Geothermal Heat Pumps have been in operation for over 40 years and operate on the same principle as your household refrigerator or air conditioner. At depths below 30 feet (10 meters), ground temperature stays a constant 42 - 55 deg F. (6-12 C)... (posted by Alexander 2 years 319 days ago.)
