What is one disadvantage of producing drinking water using distillation?
As you know water has a high boiling point, and high heat capacity... It is going to take you a lot of fuel to produce fairly small quantities of water. I have read that there are some nuclear facilities whose power output is EXPRESSLY used for water desalination...
Of course, all drinking water IS PRODUCED by the nuclear energy provided by the sun. The sun heats the oceans, the water evaporates and deposits as snow and ice, and water, on top of mountains
