- the_sleaze_ 2y agoOnly if their energy cost never increases and the figure is resistant to inflation - 500k in 1999 is now equal to $942,584.03. There's also something to be said for the carbon emissions and the fact that we can point to frozen water being a viable system.

- the_sleaze_ 2y agoThanks for this, I had never heard of qanats or wind towers. I'm imagining a giant modern qanat running underneath a city or a large dense neighborhood and each structure reaching down into it to feed a ground-source heatpump in the cooler water like roots. Everything fed by solar panels on the roofs.
