I'd imagine that most beachfront properties have basically unlimited water, but are instead throttled by electricity costs. Output water vs input water efficiency (20% in this case? 1-liter output from 5-liters input saltwater) matters in some cases, but not others. Since we all live in different terrains and locations, some inventions will be useful in some areas, while other inventions are useful in others.
