3 . The system of claim 1 wherein said closed-loop working fluid circuit comprises insulated tubing.

4 . The system of claim 1 further comprising a pump.

5 . The system of claim 4 wherein said pump is an electric submersible pump.

6 . The system of claim 1 further comprising a working fluid.

7 . The system of claim 6 wherein said working fluid is pressurized.

8 . The system of claim 6 wherein said working fluid comprises a liquid phase.

9 . The system of claim 6 wherein said working fluid comprises a mixed-phase.

10 . The system of claim 6 wherein said working fluid comprises a dry phase.

11 . The system of claim 6 wherein said working fluid comprises a single phase.

12 . The system of claim 1 further comprising a multilateral channel.

13 . The system of claim 1 further comprising a polished bore receptacle.

14 . The system of claim 1 further comprising a flow diverter.

15 . The system of claim 1 further comprising a triply periodic minimal surface lattice.

16 . The system of claim 15 wherein said triply periodic minimal surface lattice comprises a flow baffling.
