    ok so I did some reasearch on steam engines and then I had a big birght I idea use a hydrogen falme to boil the water instead of coal you would get H2O (water) as a byproduct perfectly clean water I have a blue print and everything but not a picture of my blue print I will have to take a picture my disighn is based on the uniflow steam engine it would work perfectly on a solor powered boat! you use electrolisis to get hydrogen when you are low on hydrogen oxygen from the air and water from the sea! of course you would need a compressor to but you get what I mean!

    its a viable thing that I have been working on It would be made out of aluminum except for one slide that would be magnetic to keep it inversly sychned with this sliding thing that I forgot to name its sort of like a piston though. and yes it is obvous but no one is doing it so ha! I think...

    It might be more practical to use a stationary land-based solar array to produce the hydrogen and compress it for sale to boat owners for fuel. Why cart around several tonnes of solar panels on your boat?

    thats the thing if you make the hydrogen yourself and compress it yourself with it all powered by solar panels its all free once you get it there is only a mantianence bill. :-D

    Use the electricity directly, fool.

    put will you be able to get enough juice to plow a boat through water at thirty miles an hour using electricity???? even on a sunny day. steam engines are amazingly strong a two piston steam engine is supposovly(I am a horrible speller) the same as a four piston gas engine.

    Nonsense. Your "design" will be much slower than using electricity. Electrolysis+burning will cause enormous losses.
    Stop wasting your time.

    you could use vast amounts of algea to get hydrogen from water other then elctrolosis. and all you need to ignite the hydrogen is a spark or glow plug once its lit its lit.

    Have you considered the size and weight of solar panels you would need to put on a boat to generate enough energy to electolyze water and compress hydrogen? In my opinion, and without doing any calculations, you could not produce enough real time power to move the boat. You could use small panels and store hydrogen until you had enough, but that makes the idea of having the panels on the boat rather on the dock pointless.

    Also a steam turbine might be more efficient than a reciprocating engine.

    You are wasting your time, it will not work. You can't make it more efficient than simply using electric motor.

    you don't need that many solar panels just a few to charge the boat while it is in the marina(battery) you could then have a see through top and have an algea culture underneath you coould get the hydrogen from the algea.(swamp algea thats why swamps smell how they do)

    Third try: if it's in the marina charging, then why not put it on the dock; then you can make it big and produce hydrogen for many boats.

    BUT THEN YOU HAVE TO PAY!!!!!!!!! its supposed to be free pay once and your set fro life as long as you clean the boat and mantian it and fix it when it breaks down just a mantianence bill.

    IT WON'T WORK! I tried to ease you into that understanding but it's not happening. Have you read 20,000 Leagues Under the Sea? You would like the submarine. It runs on seawater and is about as impossible as your idea.

    then how did a steam car work you have like triple the room for an engine on a boat YOU DON"T NEED A NICE CABIN!!!!! it could just be engine stuff.

    Say you want a 20 kW motor to drive your boat. A recip steam engine might be 15% efficient if you're lucky. You want to be able to drive your boat for say 4 hours between regenerating stops. That means you need 533,000 watt-hours of hydrogen. Electrolysis might be 50% efficient so you need about 1 million watt-hours. A typical PV solar panel can generate about 180 watts and is 1 metre square, so if you want to recharge in say 20 hours of sunlight, which might be several days in some areas, you would need 1,000,000/20/180 panels, or 278 square metres of panels.

    Now design your boat to install the 278 panels and recalculate the boat's weight and the motor size you need to power it. Keep iterating until you get convergence.

    Well, I forgot a few things like a hydrogen compressor, and auxiliary electrical systems you might want or need, but isn't it obvious how impractical this would be?

    yep!

    Don't forget every stage in a system will experience loses. the one after will always be less powerful then the one before. there is not enought chemical energy in your hydrogen-oxygen reaction to make up for this (if you are using air remember there will be more involved).

    Your best bet is the use solar heat (if you plan to use solar). this can drive a heat engine.

    it is also more efficent to use an internal combustion engine for heat rather than mechanical power - in this sense a steam engine will work if you used the exhaust heat from a small internal combustion engine to drive a steam engine.

    there is a very good reason we use fossil fuels as our primary power source and still remain to do so...................steam engines are dangerous (high pressure) and I wouldn't mess with them without a decent level of technical knowledge and experience.

    I was thinking of going solar using a frenell ens but every time you move it would be come "unfocoused" and then you wouldn't have any more heat no heat no steam.

    better idea:
    build a ballista on the boat, catapult the algea, the boat will propelled by the reaction force, if you run out of algea, you can replace them by batteries, solar panels, steam engines and even water

    consider a HHO steam engine with no compression or intake? could it work?



    Consider a two cycle, exhaust-combustion only engine. At TDC HHO gas and water are injected and ignited. The ignition of hydrogen and oxygen could flash water to steam, cooling the combustion and generating super heated steam, (I think?). The exhaust steam could then be connected to a turbine to generate additional power (electric?).


    This type of engine needs no starter due to no compression cycle to overcome. In a two cylinder(+) engine all that is required to start it, is the injection of HHO into the cylinder in the combustion cycle and igniting it. In a vehicle application, the engine need not run when no output power is required, say stopped or coasting.


    True, this requires both H2, O2, and water tanks, but is not O2 a byproduct of water electrolysis? Would the energy save from compression and intake cycles, as well as the elimination of gas just to keep the engine running, be at least a little more efficient? A plus, electrolysis in a closed vessel will, for free, compress the two gasses, in a sense replacing the engines compression cycle.

    Yes..Correctly..The Steam Engine work perfectly on solar powered boat...
