Patent ID: 7712326

Claim:
An energy transfer system comprising: an energy transfer device including at least one water inlet and a water outlet, said energy transfer device being positioned adjacent a structure, and spaced-apart from a water source, the water source having a sidewall; at least one water inlet pipe having a first end connected to the water inlet and a second end opposite the first end in communication with the water source, said at least one water inlet pipe extending within a respective at least one horizontally directionally drilled inlet passageway from the water source to the at least one water inlet, wherein the respective at least one horizontally directionally drilled inlet passageway extends through the sidewall of the water source; and a water outlet pipe having a first end connected to the water outlet and a second end opposite the first end in communication with the water source, said water outlet pipe extending within a horizontally directionally drilled outlet passageway from the water outlet to the water source, wherein the horizontally directionally drilled outlet passageway extends through the sidewall of the water source; wherein said at least one water inlet pipe is used to extract water from the water source and transport the water to said energy transfer device, and wherein said water outlet pipe is used to discharge water from the energy transfer device to the water source; wherein said second end of said at least one water inlet pipe extracts water from the water source at a respective at least one predetermined extraction depth, and the second end of said water outlet pipe discharges water into the water source at a predetermined discharge depth; and wherein at least one of the horizontally directionally drilled passageways extends through the sidewall of the water source at a depth of at least 80 meters below a surface of the water source.
