I was wondering if a pump-jet that converted sea water into steam and then used that as thrust would be useful at all as a method of propelling water craft, or if it makes no difference whether you're using a normal water-jet vs a steam-jet. I do not have an engineering background and do not have any clue if it would actually work or not. The idea just popped into my head.
Anyone who could answer this for me?
