    Couple of ideas to share

    If the right opportunities present themselves, I'd like to hop on board with replication of your project, given the successes and failures of my gravity mill project..

    Here's my thoughts;

      Water hammer

      I forgot to say in my video that the water pressure will probably not remain stable, and that the internal discs will probably cause a hammering effect, which I believe would be desireable.

        Hi Ben,
        Glad to have you take an interest in this project. I think it's a natural progression from the gravity engine. Besides, I can use all the help I can get.
        I watched your video and have a couple of comments. I've already tried the type of pump you suggested for all the same reasons you mentioned. Much to my disappointment it didn't work. It wouldn't raise the water more than about an inch. Since then I've done some research on centrifugal pumps and how they work. It comes down to having a stator and a rotor with some ports in it if you want it to be able to lift any water. That's a little beyond my machining capabilities.
        If you take your cone and invert it, you'll have what I'm working on now for a pump. Also reverse the direction of your spin. The water exiting in that direction has no speed.
        The water should be initially projected out through the nozzle in the direction of rotation because this adds absolute velocity to it (with respect to earth). Since kinetic energy goes up as the square of the velocity, we need all the speed we can get. Once the water is up to speed, we turn it around through 180 degrees to harvest the kinetic energy as forward torque. The conversion cycle is: pressure-speed-torque.
        This is a little counter intuitive at first, but if you think about it makes sense.

        Cheers,

        Ted

          I see what you mean

          perhaps the centrifugal 'force' can supply water suction?

          This could have adjustable nozzles both at the ends of the arms, and (not in my pic) at the base of the central water intake tube, to control suction.

          Priming can be by having full water level and facilitated by a 2 cone gearing system using a fanbelt.

          I didn't draw two gear adjusters, but that would prob be necessary.

          Then the water level could be dropped as it is sped up..

          @ted - where'd you source your motor?

              Hi folks, This is very interesting. You know I've been seeing this tapering spiral shape all over like in lamps and other places.
              Even though not totally the same, it seems Teslas turbine uses a spiraling vortex action to spin the discs efficiently and possibly with excess energy to be tapped. Similar to what Ren is speaking about of his friends device that had spiral channels in between discs although Teslas just used the adhesion effect to keep the water stuck to the disc as it spirals in towards the center outlet. Has anyone experienced or know of anyone getting high efficiencies with a tesla turbine.

                Tesla turbine

                @Skywatcher - No idea, but the tesla turbine and it's theory are on my research list for this contraption.. He did say it was his finest achievement, which is saying a lot.

                  water exit speed

                  @ Ted - wouldn't the water in this setup exit at the same speed as in yours?

                    I don't think it's so much the exit speed of the water as it is extracting the kinetic energy. My intent is to wring every last bit of energy out of the stream and convert it into torque. Going through 180 degrees takes twice as long as 90 degrees, thereby converting just that much more energy.
                    Plus, if your nozzle is facing straight out, you can't take advantage of the summing of velocities (rotational velocity + nozzle velocity).
                    To answer your question about the source of my motor: I scrounged it. It came from a 12 volt air compressor we use on some of our trucks at work. I like DC motors because I can easily change the direction of rotation, and they have good low speed torque. 1/3 hp is a little on the edge though. 1/2 or 3/4 hp might work a little better. The junkyard is our dear friend.

                    Cheers,

                    Ted

                      Hi all, this I have posted before in another form, but is how I see this, all be it a little complicated to build

                        Schauberger

                        Hi all,

                        in some of the former postings some of you have spoken form Viktor Schauberger.

                        1. Schauberger used devices with hyperbolic shape. There's a store in Switzerland where you can by this units. WYTOR Schauberger-Trichter, Hyperbel, Wasseraufbereitung, Wendelrohre.

                        is it possible that you want to reinvent the Segnersche water wheel?

                        3. I am no Schauberger expert. But this makes me thinking: Why does Schauberger called one of his devices Repulsine (re-pulsate/pulse). I think he called it Replusine because the fluid which eject from the unit push against a rim. 't the = re-pulsate

                          Hi Alana,
                          Interesting device. The Segner wheel is similar to what I'm trying to build except that he is using the power of falling water to drive a generator. I am attempting to use the power of centrifugal force and resonance to power mine.
                          I wonder what Segner does about his hole filling up with water?

                          Cheers,

                            Lol, maybe the powered device is a pump. Would that be COP > 1 ?

                              archimedes

                              @ stealth - can you do a little drawing of your design? i've debated using the rotation to draw water up via an archimedes screw but have been stumped at how to implement it in an actual device

                              with three of us working on this from different angles, it could get quite interesting.

                              also waiting eagerly for any pics from ren.

                                Basically you'd need the equivalent of a drill bit in a sleeve. Think of a drill bit boring a hole. The shavings climb up the flutes of the bit and out of the hole. A sleeve around a spirally fluted shaft may do the trick. Make the screw turn in conjunction with the turbine and make the sleeve stationary; much like an extruder for plastics. This will also create some heat increase due to friction of the water between the sleeve and screw creating an increase in pressure as it runs.
