>>11567066The nature of desalination makes me think of the distillation process.
Is the left side supposed to represent an intake? and the right side being a steam output into a condenser like picrel?
I've got a distillation rig in my shed that I've been experimenting with. I'm not averse to angle grinding/machining/welding new parts either.
Sometimes it's always easier to get an idea drawn out, so this process may help.
