Abstract
The present invention provides components with metamaterial structures for use in enhanced geothermal systems.
Claims23
A casing connector for a geothermal well, the connector comprising:
- a hollow cylindrical body with upper and lower ends;
- and
- a bellows disposed within the body, wherein the bellows comprises a form defined by at least two sets of intersecting or interfering corrugations.
A casing connector for a geothermal well, the connector comprising:
- a hollow cylindrical body with upper and lower ends;
- and
- a bellows disposed within the body, wherein the bellows comprises an undulating surface defined by intersections or interferences among two or more sets of corrugations.
A casing connector for a geothermal well, the connector comprising:
- a hollow cylindrical body with upper and lower ends;
- and
- a bellows disposed within the body, wherein the bellows has at least two sets of non-parallel undulations that meet or cooperate to define open cells along a surface of the bellows.
A casing connector for a geothermal well, the connector comprising:
- a hollow cylindrical body with upper and lower ends;
- and
- a bellows disposed within the body, wherein when pressure is applied axially to the connector, open cells along a surface of the bellows promote deformation of the connector axially to an extent greater than that of a connector made with a bulk monolithic structure and no open cells.
