You're over-complicating it. It's simply heating, cooling and capturing steam. There is no manufacturing. You make it sound like there's a smoke stack in my house. Speaking of which, Nature has been "manufactured" or been impacted by man to a large degree. Contamination of most water supply is ubiquitous. God's laws gave you a brain to make tools to your benefit -- to adjust to your environment. Shall we ignore those God-given laws? Do you not build shelters, make fire? Or do you rely on only what Nature gives you? At what point do you use your brain? Isn't thinking a God given law? Again, where does your "clean", natural water come from? Simple question.
