      To all of our new members,

      Welcome. Like most groups we run the Gamut of interest and knowledge. At
      present there isn't a high level of activity. I, for one, hope that you
      will help change that. Tell us a little bit about yourself and your
      interest in the little steamboats.

      They bring back childhood memories for me. I have been trying to design
      a POP-POP Clermont as a result of recently found interest in Robert
      Fulton. More later if interested.

      Again, from Old Frank, Myself and all of our members Welcome.

      Pete

        That's right, Pete,
        There is not much activity on the forum. However, this doesn't mean
        that there is no pop-pop activity. Last week I travelled to the
        Netherlands to meet first in Amsterdam a specialist of coil engines
        and then in Leeuwarden two students who intend to propel by means of
        a pop-pop engine a real size boat with two men on board. This boat
        will run a race this month in the framework of their studies with a
        pop-pop engine… heated by the sun. Yes, a solar pop-pop. As if things
        were not enough difficult… Due to the very weak power developed by a
        pop-pop engine they have not the least possibility to win the race
        and they are aware of this. However, what is very interesting is the
        fact that their first solar pop-pop engine worked. I'll let you know
        more ASAP.
        Two months ago these students built a very interesting pop-pop engine
        with many pressure and temperature sensors, but unfortunately the
        design of the engine was not good enough to get a reasonable thrust.
        That's a pity. And I'm afraid they will never build another one
        because they will finish their studies next week and then they will
        start a new life.

          Hello there,

          I have to admit that I haven't been able to work on my pop pop project
          this winter, I was focused on my iceboat model that just seems to be
          unusable actually but I'll be back on the ice next winter here in
          Wisconsin.

          Jean Yves, this is not fair to tease us like that, the folks here are
          I am sure just like me really really eager to learn more on these
          projects ! Whatever, it just seems that seeing these boats was worth
          the trip, I am sure that you are back with lots of pictures and good
          diagram for us.

            Well thank you,

            Allow me te introduce myself. I'm Paul, 33 years old and I come from
            the Netherlands. One of my (too)many hobbies is to improve things by
            trail and error, in our case the putput or 'pufpaf' engines as I like
            to call them.

            My first experiment was a simple aluminium coil type engine but after
            blewing a gap in the pipe I discarded this attempt. My second engine
            is still in a experimental fase as it continous to run quite voilent.

            It's a brass box design(80mm*25mm*10mm) with an ultra thin membrane
            and 2 nozzeled rear pipes. It runs on a tealight, mostly noisy with
            reasonable performance but sometimes it overheats and stalls.. which
            is bad as I didn't designed it that way! A pro of the design is that
            it is nearly impossible to run it dry as the pipes are fitted about
            2mm in the angled boiler so there will always be a certain amount of
            water in it.

            My new design will be quite unusual. Instead of 2 rear pipes it has 1
            inline pipe with an in only valve at the front and an out only valve
            at the rear. (valves are madee from bicycle tires) The membraned
            boiler is connected with an angled pipe to the valved pipe. The most
            unusual in the design however will be the membrane. It delivers an
            unused source of mechanical energy and I'm about to chance that.

            I hope to post some pics soon, for know.. stay happy and keep
            experimenting with those strange tiny steamers.
            Don't hesitate to ask questions.

              The 2nd design is very nice. Are the valves operated with sliding magnets? And do you have a working model already?

                  The second design would use an R/C servo to move two permanent
                  magnets. There are no models workingâ€" or non-working.
                  If I tried to develop a model, it would be based on the first design,
                  using damper plates to control heat distribution to the ends of a
                  reversible duplex coil engine. the tricky part would be in finding a
                  heat source that would keep both ends operating when the damper plates
                  were centered and provide quick responses when the plates were tilted
                  in either direction.
                  Developing a model based on the second design would be more difficult
                  because of all the interactive variable factors that would have to
                  come together to make it workâ€" somewhat like opening a can of worms
                  and expecting them to crawl in the same direction as ranks and files
                  the first time out.
