"...water turns to gas through evaporation at lower temperatures so maybe you can just distill that vapor in smaller amounts."

That actually is "a thing" in chemistry. Called "sub-boiling distillation". Elimination of bubble formation and subsequent breaking drastically reduces contaminant carry-over and yields a much purer final distillation product. Used primarily in the production of ultra-pure reagents for ultra-trace analysis.

Yes, very good. LENR is an “ultra-pure reagent” of fusion. I like it.
