    Conversion of the propane (internal combustion) engine to hydrogene cost nothing (may be a little adjustments of the gas mixing equipment).
    So if you fill one of the boat's compartment with metal scrap and your plastic tanks with low concentrate of sulfuric asid and water mixture, then the out put of the chemical reaction between these two would be a lot of clean and cheap hydrogene. Will this scenario work?

    its hydrogen in english.

    and had to believe you could create hydrogen cheaper than propane when its all said and done.
    Most likely significant explosion risk with oxygen and hydrogen being present.

    I think it works until the moment when someone needs a cigarette.
    But you may be right: Making boats isn't ROCKET SCIENCE!

    propane boats

    Propane boats work just fine. Each aluminum forklift tank will run a 502 cu motor at 3000 rpm for 30 minutes.

    What happens to the water in the engine after it is stopped? How do you keep the engine from seizing after one use?

    water ?

    There is no water in my engine... There's a heat exchanger with antifreeze for coolant which stays in the motor and doesn't rust. New Zealand has done it for 15 years with no problem. the only downside is shorter run times. 2 hours max

    pistnbroke I try

    How are you getting the acid vapour out of the hydrogen/oxygen mix ?

    jetboat jay is right: 5 metric tonns of scrap produce 1000cu.m of hydrogen, so it is only for couple of hours on full trottle for 300hp engine.

    When hydrogen and oxygen combine, they produce water H2O. What happens to the condensate when the engine stops? As it cools, the water will sit on top of the pistons.

    Automotive propane powered engines never run on the single propane itself. They start on the gasoline, then change to propane when warmed up. Many diesel engines have so called turbo timer, so this timer shuts down engine automatically after 1-2 minutes idling.
    Same can be technically applied on the hydrogen powered engines. Only problem, as i said, too much consuption, expressed in volume of the hydrogen.

    Dont know anything about it, but I see the Swiss company Silicon Fire are producing Hydrogen Methanol fuel stations for lake boats built by Feller.

    "Automotive propane powered engines never run on the single propane itself. They start on the gasoline, then change to propane when warmed up. "

    That is the drill for running 75 year old engines on kerosene.

    There are hundreds of thousands of stand by house generators , and RV generators that use ONLY propane.

    In addition there are thousands of delivery trucks and fork lifts that have only propane.

    Propane is a far better fuel than gas , higher octane , and no residue when it evaporates in the carb.

    Gonzo; No water is left behind in the pistons because it all goes out with the hot exhaust as vapor. Water is the by product of all hydrocarbon combustion, even gasoline. Hot exhaust gases carry it out the tail pipe as vapor. Where it condenses out is near the end of the exhaust pipe where gases start to cool off, that is why the tail pipe rusts out first, and the seldom does the head pipe rust at all.

    Yuri. Hydrogen fuel should be one of the lowest cost fuel to make since it is one of the most abundant elements on the planet, but only if done in process plant. It is nearly impossible to make H2 gas as you are underway because the size and mass of the raw materials required would be too large and too heavy. You have to make the H2 at a stationary plant and find a way compress it and carry it. H2 as a fuel is very light but it takes a lot of pressure to make it liquid (way too dangerous). As a gaseous fuel at lower pressures it would take up the whole hull in volume and you would have no room for cargo/passengers. Best way to store low pressure H2 is in hydride storage cells, hydride absorb H2 in large quantities and will release it when heated. That is the most practical and safe way to store H2 gas, but they are costly to make. You would make large sealed tanks full of iron hydride pellets with heating elements running through it, the lower part of the hull can be used to act both as fuel tank and as a ballast, little weight change as the H2 gets consumed. You could supplement the H2 with a few tanks of propane so if you are out of H2 away from your H2 supply you can buy propane to get back to homeport.

    H2 as a fuel is clean and light, puts out no carbon (if that is your concern), and no pollution.
