Tehran, Iran, has run out of water

42. I'll admit to not understanding the details BUT

2 points:

1. the water can not (er, SHOULD not) be discharged directly back to the environment, as in discharged to a body of water, while it is above the temperature of that water. Yes, you said closed-loop - but it certainly was not this way in the past, back when I was paying more attention in this specific area, it was a huge problem - power plants and industry using water for cooling, then discharging heated water back into the environment, thus raising the temperature of whatever body of water they were discharging to. (much aquatic life is rather sensitive to temperature, so raising the temp is not a good thing)

Given the relative cluelessness on both sides of the aisle, and the actual malevolence on the reich-wing side, I doubt that there have been substantive and sustained improvements in how energy-hungry entities operate in this regard.


2. Closed loop would be great, but given probably not (point 1 above), I'm presuming there's some volume loss throughout the process. I'm not 100% sure there isn't a small loss over time even with a closed loop. (by closed loop I assume you mean as in a ground loop geothermal system. Which they all should be using but I can pretty much guarantee they are not.)
