Solicitante:

BERMAN ARI PETER [US]

Resumen de: US2019145666A1

A new system for and a method of deploying a heat exchanger pipe. A bore hole is drilled from an access ditch location to a terminal ditch location using a piloted drill head powered via an umbilical attached to the piloted drill head. A casing is attached to the piloted drill head and disposed about the umbilical into the bore hole from the access ditch location to the terminal ditch location. At the terminal ditch location, the piloted drill head is removed from the casing and the umbilical and a heat exchanger pipe is attached to the umbilical. The umbilical is withdrawn from within the casing deployed in the bore hole to pull the heat exchanger pipe into the casing. The casing is then withdrawn from the bore hole leaving the heat exchanger pipe in the bore hole.

RAYTHEON BBN TECHNOLOGIES CORP [US]

US_2018013048_PA

Resumen de: WO2018009573A1

A sensing system including in-ground sensors not requiring battery power. A thermoelectric generator sensor rod includes an upper thermal contact and a lower thermal contact at or near its two ends. When the thermoelectric generator sensor rod is buried in the ground with one end buried more deeply than the other, a temperature gradient in the soil produces a temperature difference between the upper thermal contact and the lower thermal contact. The upper thermal contact and the lower thermal contact are thermally connected to a thermoelectric generator, e.g., by heat pipes or thermally conductive rods. Electrical power generated by the thermoelectric generator powers sensors for monitoring conditions in the ground, and circuitry for transmitting sensor data to a central data processing system.
