This reminds me of Dune. Does this really work tho?

Most likely not. Hard part really is rejecting the heat involved in phase change of water from vapor to liquid. You have to effectively dump that energy somewhere and all the time you do not you don't get liquid water.'

It sounds easy, but eventually you can heat up whatever you use as heat sink and then you have to wait for that to cool.

I honestly can’t believe the article didn’t mention dune.
