Solving two Anthropocene problems with a self-sustaining loop

Another proposed combination of technologies may result in a synergistic cost saving by creating a self-sustaining loop.  CO2 removed from the atmosphere by Direct Air Capture (DAC) is stored in deep, hot aquifers.  Heat brought to the surface could then be used to power the DAC process.  Thus the excess CO2  itself could reduce the high cost of removing it from the atmosphere. 

Like the nearby geothermal source I wrote about eight years ago, however, this particular hot spring would not be a suitable location for such a self-sustaining loop.
