Abstract
Systems and methods of the present disclosure relate to generating electricity by pumping fluid into a thermoelectric conduit that extends into a geothermal reservoir. A method includes pumping fluid into at least one thermoelectric conduit that extends into the geothermal reservoir. The method further includes generating electricity with the thermoelectric conduit due to a temperature differential between the fluid and the geothermal reservoir.
Claims20
A method comprising:
- pumping a fluid into an inlet of a first thermoelectric conduit and an inlet of a second thermoelectric conduit, wherein the first thermoelectric conduit and the second thermoelectric conduit extend into a geothermal reservoir, wherein both the first thermoelectric conduit and the second thermoelectric conduit comprise a helical shaped portion, and wherein the helical shaped portion of the first thermoelectric conduit is positioned within the circumference of and circumscribed by the helical shaped portion of the second thermoelectric conduit;
- and
- generating electricity with the first thermoelectric conduit and the second thermoelectric conduit due to a temperature differential between the fluid and the geothermal reservoir.
A system comprising:
- a first thermoelectric conduit and a second thermoelectric conduit extending into a geothermal reservoir, wherein both the first thermoelectric conduit and the second thermoelectric conduit comprise a helical shaped portion, and wherein the helical shaped portion of the first thermoelectric conduit is positioned within the circumference of and circumscribed by the helical shaped portion of the second thermoelectric conduit;
- and
- a fluid source and a pump in communication with the first thermoelectric conduit and the second thermoelectric conduit.
