    My picture explains how traveling wave works when crossing the firm soil. Car wheels work the same way.

    I would like to hear your opinion about screw drive’s advantages and disadvantages

    Hey Vlad

    Your ideas are really going in the right direction IMHO. I have been interested in the concept for a long time, and even introduced a few threads about it over the years.

    My preference for the "undulating" amphibious propulsion system would be a series of air inflated rubber tubes, perhaps moving a series of protective surfaces.

    For this you would need a compresser, air lines and no through hull holes.

    This would do away with the cumbersome "push rods" in your earlier diagrams, and make the mechanics much simpler and more robust. It would also lie flat against the hull when deflated (not in use) if you wanted to engage sails or auxilliary props.

    The undulating method could be supplemented by a retractable prop for deep water operation, but for sand, shallow or rocky places, you would be just like the seals in the previous posts.

    It would get you to remote and fascinating places that other vehicles could not contemplate

    You will continue to think this way until you understand how travelling wave propulsion device work.

    My question is what is the goal to be accomplished by this future boat that cannot already be done with existing vehicles? Don't we already have submarine, amphibious, all terrain craft, hovercraft or even helicopters, that would work for every conceivable terrain? Is the goal to have the versatility with more economical drive, at greater speed, with less power or less weight? Is the goal to surpass selected sea creature propulsion by mechanical means?

    I believe a version of the hydrocopter might have the capability for land travel if the propelling blades were strong enough, so might be a contender.

    If you can’t see goals, this problem is not interesting for you. Try to attract others attention to your hydrocopter version.

    I would think it boils down to efficiency, the screw drive or the undulating drive both; I would think, have much higher resistances than say wheels or propellers. Ends up being a mater of fuel economy although in some terrains the screw drive seems like it would actually be able to move better.

    I thought it was slick that it can go dead sideways as well

    but still not much practical use unless your living on a semi frozen tundra

    cheers

    Unfortunately a working model of the amphibious vehicle with the travelling wave’s propulsion still does not exist. That is why it is hard to compare these drives. But what is clear for me in some terrains they would be able to compete with each other.

    Thank you

    Well, no, you didnt really.

    "A rotating control assembly regulates longitudinal expansion and contraction of cells ....."

    Thats a mechanical method, though it does manipulate "cells", but there is no discussin on inflating and deflating with compressed air

    and further

    "substantially flexible spine fixed by said connecting means to the frame only at the center of mass"

    He is using a mechanical technique.

    Valid points Boston, but if you have been 4 wheel driving, you will know what a limited range of enviroments you can travel across, and you have to carry winches, spades etc for the unexpected.

    Also, a lot of unexplored territory can only be accessed by open water.

    In my mind (twisted though it may be) - I travel say 100 kilometres of fairly rough open water in conventional boat fashion, "crawl" across a shallow sandy bar entrance that blocks a river (that would bog a 4wd, and be too far away for a small hovercraft), float up to the first set of rapids (that would sink a 4wd) crawl up the river over the boulders and loose pebbles (that would ground a boat and smash the underboady of a hovercraft), crawl across a boggy button grass plain (that would halt a hovercraft with the small stunted bushes preventing sealing around the skirts, and would bog a 4wd) and continue on into the unexplored area with minimal environmental damage due to the load spreading of the inflatable exterior.

    Just a dream at this stage, and lots of practical problems to overcome.
