I dont know why this keeps coming up? It is a closed loop system. The water aren't used at all.

Many data centers use evaporative cooling.

It's a closed loop on the geo side sure.

How do you cool the steam off enough to condense so it can go and be boiler feed water again?

Lots of power plants use cooling towers for this which are typically evaporative. Some are dry, sure, but most are wet.

Our method is open on both ends. It draws from one layer of the aquifer and then returns the water to an adjacent layer.
