    @Gw Builder Rather sure that algae is an adequate producer of oxygen. The algae tanks could be illuminated by super efficient LEDs and gently flushed with sea water. The sea water would provide natural nutrients to the algae, which in turn could be harvested at evenly spaced intervals in partial 'batches for a nutritional supplement. Just an idea. Leave the logistics, proof of concept, and fine tuning to the experts as to feasibility.

    Clinker : is from Dutch, and was originally used in English to describe Clinker bricks .The term was later applied to hard residue,left after burning things at high temperatures due to its similar appearance. Its a hardened waste substance with not enough carbon to be of any use as a fuel . it was sometimes used for pavement. So their spent candles might make handy garden edging 😉 . thats my unsolicited 2cents 😶

    The preheater to the boiler stripper is nothing more than heat integration. Some waste heat from somewhere else on the ship is, I'm presuming, captured via a fluid and transferred there as a means to reduce the heating requirements of the boiler. Similar techniques are used in plants to offset utility costs. Here, probably done for safety reasons.

    I've seen an attempt to use this same technology to harvest hydrogen from water then inject it into the induction system of petrol/diesel engines which supposedly resulted in lower emissions and an increase in fuel economy however it's unclear if the end result was worth investing in as the gains were relatively small and therefore required that one do a lot of mileage for it to pay for itself. I believe the company was called 'CGON systems' and they were based in SW of England.
