    or better yet if you can slip it into a tank ?

    No the elec motor is not going to be a part of this heat test ,yes that is not completely fair because your motor makes heat too...

    however,
    you are really going to like finding out "what you got "!!

    There is a line in the sand ...one side of the line people yawn and scratch their shorts.....say, yeah no big deal.

    The other side of that line ................

    the line for heating water ?
    roughly
    you take 0.1 kwh , thats exactly how it will look on your KWH meter [0.1]
    one liter of water 120 degrees temp rise.
    two liters 60 degrees
    etc etc
    thats unity [well close enough for this test]

    so when your done building the tank ,measure its volume
    do the math.
    don't start your test until the temp of all components has stabilized.

    Conversely you will have to let it "sit a bit" after the test due to your "stored heat issues".

    That being said if you hit the line [temp rise] at shut down,
    Do the happy dance.

    one other thing that you should do is a control run, take a cheap immersion heater with your exact same water volume and run 0.1 kwh of power
    check the temp.

    I have simplified the process, before you do a run call me.

    PS
    One thing I should mention
    if you cross that line,your life is going to change [along with everyone elses.......]
    Hello
    Thank you and I will getting in contact with you for the testing.

      Hi Slapstick and All,

      I wanted to build one of these for a number of years and have been collecting # 10 can steel lids that were cut out from the top of cans to build my version of it. I have probably 30 or so now, but have not drilled them to mount to a shaft yet.

      I could use your help so that I don't have to go through the same 1,000,000 test versions and experience the same bugs you have found.

      There is a drive motor energy saving circuit called the Rotoverter that does spin a 1 horsepower 3 phase motor on about 20 watts (or less depending on bearings etc...) - no load. I don't know the amount of motor torque that your heater requires, but if it can spin very freely, and doesn't use gobs of motor torque, then the Rotoverter might be a good swap for your 500 watts no load motor.

      One question I have is my #10 can lids have corrigations in them (concentric ridges). If I use them, then I would need matching ridges or rings for the stationary disks?

      I know Konehead of EVGRAY forum built one similarly and used 1/4 nuts each side of disks on allthread but his didn't work out too well. There have been a few others with sucess and others not. Do I need to have a machine shop for the close tolerances?

      Anyway, Congrats on your progress and willingness to share.
      Ken
      Hello Ken
      You don't need a machine shop but it really make it easier for the tight tolerances.
      As far as the corrugated metal you are using, the spacers will have to match.
      It would be a good way to get more surface area in a smaller core. Almost like Viktor Schauberger repulsine design. He did design a heater that was similar to the repulsine.

      Thank you
      Gabriel

          Hi slapstick and all,

          I understand when you say that most all is available here and on youtube... I know cause I contacted you through youtube few months back. I didnt act on it cause of free time then, but I got to tell you.

          Replicating is not the same as merely constructing. If I am to replicate your device I need sketching if I cant get them, then it can be an attempt of replica based on my understanding and we wont have 100% accurate results cause if the device dont work on my side then it will be due to some error I made, or something else... Hope you understand what I am trying to say and why sketching and details are all that important.

          Thanks

          P.S. even if you dont get sketches, I will go ahead with trying to replicate, I appreciate the time you took to show us how you did it.

            Hello Slapstick,

            Thanks for posting you video link.

            I was just wondering how you arrived at that pulley ratio you are using. Perhaps you can drive it faster with a different set of pulleys and get even more heat out for the same power consumed. I could not tell if you are really loading that motor to it's rated output.

            Thanks again!

              Hello
              The pully setup is to keep the high temp from getting to hot and flashing the oil. With that being said, I have ran into a issue with the oil I have been using. I will be using a new kind of oil that has a higher smoking temp. The old oil that I was using had a smoke temp of 400F.
              The new oil I will be using has a smoke temp of 700F. This will allow me to get higher temps and not burn the oils.

              If anyone knows of an oil that is non toxic with a higher smoke temp please feel free to share. This is still a work in progress and I am tying to push this as hard as I can to get the most out of it.

              Thank you
              Gabriel

                If you find a way to loose heat immediately from the can you don't need a high temp oil I think.

                  Thermal Conductivity

                  Hello Slapstick,

                  If the outer body is made of stainless steel then I think you can do very well with what oil you have right now if you change the material of the body and the spacer rings to aluminum.

                  The choice of material makes a big difference as was shown in the example here (scroll to the bottom of the page): Thermal Conductivity of some common Materials and Gases

                  In essence, you gotta lose that heat to the atmosphere at the same rate as it is generated in the oil, otherwise the oil temp will just keep on rising until the entire system reaches equilibrium (heat generated = heat dissipated).

                  Just an input for you and I wish you all the best with this project of yours. Fantastic results!!!

                    It is the same problem as the car engine.

                    You need a radiator and a circulating pump, both possibly from a car
                    scrapyard. With these in place, could you not then exchange the
                    oil for water?

                      Hello,

                      I am trying to get the core heat up as high as I can before drafting the heat off of it. I do have one with a heat exchanger and I am running into the same problem with the oils. I am going to be running wight mineral oil that has a smoke temp of 700F and the same viscosity as the previous oil. After this is all done and perfected then I will implement all aspects of the Core itself. Trying not to put the cart before the horse

                      Thank you,
                      Gabriel

                        Hello,

                        I get this week new laser cuting disks. Then I can carry out other tests.

                        Greeting

                          This is tough to interpret. (You mean 14 cents per KWH, I take it).

                          If the device is powered by electricity (at 14 cents per KWH),
                          the input power should be approximately 333 watts.

                          333 watts could not keep your house toasty warm.
                          Therefore, it would seem likely that the device is overunity,
                          and by a considerable amount.

                            Hello

                            I will be sending off one for proper lab testing to see what all is going on here.

                            It does keep my house very warm and for a very cheap price.
                            For the month of December I will be running base board style heaters and keeping track of the KWhs used in the month of January I will be running my heater and keeping track of the KWhs used. I will track the inside Temp and out side Temps on a day to day, along with the inside Humidity.
                            At the end of January I will be posting my findings.

                            Thank you

                              Just built one from paint can. Going for improvements soon.
