You can pump water back after it condenses?

  Assuming you can scavenge 100% of super heated water. There is always going to be some loss factor. And if a geothermal installation is going to need several hundred million litres of water then an installation in an arid area will still be problematic. It also comes down to how that heat is harnessed - will they be channeling the latent heat up and using it to generate steam at the surface, or will they be pouring the water down into the interior and converting it to steam within the subterranean chambers and harnessing the resulting steam pressure coming back up etc.?

    After the water went through the turbine it's not superheated anymore. You probably have a condenser already to improve efficiency. I wouldn't be surprised if it's a completely closed loop anyway.
