Patent ID: 7647988

Claim:
A method of drilling a hole into the ground and installing a geothermal transfer apparatus, the method comprising the steps of: positioning a sonic drilling apparatus at a desired location, the sonic drilling apparatus including a rotating and vibrating apparatus for rotating and vibrating a hollow drill string into the around, the hollow drill string having an inner space; drilling the hole to a desired depth by rotating and vibrating the hollow drill string into the ground and discharging a fluid into the inner space of the hollow drill string; fitting the geothermal transfer apparatus to a reinforced steel structure and lowering both the geothermal transfer apparatus and the reinforced steel structure into the inner space of the hollow drill string following the drilling of the hole to the desired depth; and removing the hollow drill string from the ground, wherein said geothermal transfer apparatus is one of a coaxial flow geothermal transfer apparatus, a geothermal transfer loop, or a geothermal transfer apparatus comprising a thermal superconducting medium.
