I guess there are some practical issues. Maybe some sinks into the mantle or gets salty or something. But on the other hand, we know the reciped for water and as far as I know there's a lot of hydrogen and oxygen floating around.

Yeah, I've always thought the same. The problem is that we are too dumb to live and do agriculture in the areas that receive adequate rainfall. We keep stubbornly trying to build cities and farms in deserts.
