Title: adressing two issues (fresh water and energy)
Post by: Emilio Romero on 22/09/2008 19:35:40
Would it be possible to generate (some) energy (electricity) in the process of desalinization of sea water?

You couldn't generate any net energy, since it takes a significant amount of energy to do this.

Well, it depends on how much energy and how much water. Inasmuch as power plants have large quantities of waste heat that must be dissipated, it would be possible to distill at least some water using it.

It also depends upon how efficient the desalinization process is. There are crude ways to distill water that consume large amounts of heat; then there are more sophisticated ways that consume much less heat.
