System and methods for enhanced thermal syphoning

A thermal syphoning system comprising a first well and a second well extending though a permeable geological layer, each well having:

• an inlet channel to introduce a fluid into the well and an inlet valve to control an inlet fluid flow rate into the inlet channel;
• an outlet channel to draw the fluid when geologically heated fluid from the well and an outlet valve to control an outlet fluid flow rate from the outlet channel;
• and
• an opening in the inlet channel adjacent the permeable geological layer,
• wherein the inlet channel of the first well and the inlet channel of the second well are in fluid communication with each other such that the inlet channels receive heated fluid from each other via the permeable geological layer and through the openings in the inlet channels, wherein each inlet valve and each outlet valve can be adjusted to vary a flow volume of the respective fluid between the first well and the second well to thereby control a temperature of the heated fluid drawn from each well.
