    I look to Nature to provide inspiration when prevented by a novel problem such as that. Hmmm: open water, bog, rapids, pebbles and swamp. That would have to be a bird!

    Let’s talk about travelling wave’s propulsion please. Picture below can help to continue our discution.

    Thank you Mr. Watson. I should learn more about it.
    It seems to me a new aquatic sport Water Walking Ball also uses traveling wave’s propulsion.

    how about rotating ovoids kinda like elongated spheres
    they could even be solid but they would still be "walking" along a wave of there own creation

    rather than an undulating membrane

    same principal just differing approach

    oh sure
    did I hit the nail on the head or something
    let me guess
    the rotating ovoids within a membrane to keep em clean

    so
    how close was I :p :p :p :p

    you can tell me
    I promise I wont put it on the internet :D

    English language is rich enough to explain everything. Could you make clear your idea or give us a picture please? I can’t comment your writing.

    Yes, a valid concept. As I say, I was keen on avoiding as much mechanical stuff as possible, and the ovals would have to "fit" somewhere when not in use. They would certainly take up less space than say wheels or other mechanism.

    Rather than "undulate", I was envisaging quite robust "pillows" that inflated and deflated like compressed air shock absorbers, with quite a bit of muscle behind them to lift and propel heavy craft.

    Better not say too much more or Vladd will get miffed.

    I was kinda picturing a series of cylinders that instead of being round in cross section were maybe ovoid
    place them like rollers one behind the other inside a membrane and you have a sinusoidal wave machine

    To have a traveling wave machine you need to rotate these cylinders at equal phase intervals so as to produce a traveling wave in the flexible membrane so that a complete wave passes during each full rotation of the cylinders. On my picture of the traveling wave's propulsion device the crankshaft plays this role.

    That looks like an ordinary car crankshaft. Surely it wouldnt be any use for making waves for a boat ?

    It will be very useful if it will be made in compliance with my traveling wave propulsion device's picture on this page.

    I cant see how that will work. The camshaft appears to be from a horizontal four cylinder engine, where one piston on the opposing side is always opposite the other two cylinders.
    Your device of continuous sine wave vertical rods will require a continuous variable 'throw', and a lot more lobes than this camshaft has.
    More information would be helpfull.
