Widespread use of these could eliminate disease-spreading sanitation problems around the world, at least in places that don't have open sewers alongside roads.

Another application would be irrigation for farming. A lot of land that's now desert could become fertile, thereby reducing malnutrition.

Nuke-powered desalinators are a win-win idea.
