  • @luno:

    Where is the article from that you posted, because the link to skif you posted is about Melnichenko ?

    I see it like that. If Dudishev really would get 10KW out of an ordinary triode, then his website should somehow at least reflect that. I donґt see that mentioned anywhere.

    Will research that a bit more though.

He says that an ordinary vacuum tube can be used to produce great currents up to 10KW if anodes and cathodes of the triode are cooled. All you need to do is apply short impulses of positive high voltage to the grid of the triode and the HV ground goes to the anode. This way cathode emitted electrons are accelerated to the anode in a avalanche fashion and then this current goes through the load to the cathode and is again recycled and accelerated.
      Hope this helps and hope I understood everything right.
      Sounds like Correas PAGD

      • hello all,

        SPeaking of Melinchenko, it is an interesting little experiment i have done yet not OU sign in my setup. Perhaps it needs extensive fine tuning and large components.

        By the way, being inspired by the Steorn tech, that maintain as a key technology pulsing a coil to a semisaturated core by an external magnetic flux (small impedance) and then collapsing it without the influence of external magnetic flux (higher impedance)... gains energy! lol

        Interesting little concept. I make a series of experiments in core saturation of solenoids, toroids and EE cores, and i can see that the application of a suitably oriented external b-flux (orientation plays a major role), results in considerably diminished self-inductunce hence impedance.

        I guess the trick -if there is such- is not to pay more for the external b-flux creation than the surplus energy "created" by diminished inductunce.

        ...
        More or less the concept is the same as Melinchenko's with the main difference the secondary passive coil is not passive as well. It is pulsed too.

        Experimenting...

        • Hi everyone,

          If you have some problems with Google translation, post the incomprehensible phrases or words, I'll correct them.

          You can find some information about Melnichenko also from:

            • you may really enjoy this as it contains many of the same elements described in that translation.

              Photomultiplier - Wikipedia, the free encyclopedia

              especially in conjunction with the multipactor effect, and secondary emmision

              Multipactor effect - Wikipedia, the free encyclopedia
              Secondary emission - Wikipedia, the free encyclopedia

              Short explanation: An electron may be accelerated into an anode, where if it has the correct kinetic energy, it may knock 2 electrons free, which may accelerate to a second grid and knock 4 free and so on. To accelerate them requires NO energy, only static electric field.

              • The question is :
                How do you scale this up from a small signal (light) application to a power application?
                It seems that it canґt be scaled up. Unless you give credence to an unsourced article related to Dudishev that doesnґt go into detail about what tubes are used at what operating parameters.

                  It could be difficult, look up Farnsworth multipactor tube

                  • Electron beam tech:

                    Hi All

                    I was just reading through here and I thought that I would post this design of mine as it is more or less what you are talking about. This has a current draw of 2amps, but it has an output of 7amps.

                    It uses two HV supplies, one at 20% of the other, and I use flyback transformers which I can regulate from 0-30KV.

                    This is electron broard beam tech:

                    Enjoy
                    Mike

                    • Mike,
                      this sounds interesting!
                      Looks more like an Ed Gray tube with the difference that here the grids are grounded and electrodes (?) brought to 2 different high voltage potentials (as it looks like), which some people have speculated Gray had actually done and why nobody could reproduce his results.
                      Would it be possible for you to elaborate on how you run the HV circuits?
                      At what frequency or is that not crucial?
                      Do you have photos of your tube? From the illustration itґs hard to imagine how the inside looks like.

                      How and where do you extract the 7 amps?

                      Regards,

                      • Speaking of Melnichenko

                        Hi everyone,

                        I made some tests of a motor from microwave oven using Melnichenko method. Fed with 220 v from mains it takes 150 mA. Fed with 93 v from transformer in series with 2.4 µF capacitor you have practically 220 v on the coil and you need only 115 mA from mains. See details on the picture joint.
                        I began with 28 v from transformer. With 2.4 µF capacitor you have 54 v on the coil. But if you add two magnets ( one ceramic near the rotor and other Neo on the top of the coil) , you'll have 60 v on the coil. I didn't measure the RPM but it seems to be the same (the same sound of the motor). Don't use ceramic magnet on the top of the coil it will die (the magnetic field dissipated from the top is very strong and you can use it also: two coils attached on the ends with one Neo magnet + one string in the centre of it or simple coil with iron core).
                        But with 93 v no advantages of magnets found.

                            • Luno, thanks for the link.

                              I am shaken a bit. There is certainly something to vacuum tubes, but the video is not really convincing as it shows nothing than a guy with a kacher playing with a plasma globe.
                              The site seems to be run by Dudishev and he is selling stuff, that makes it a bit odd.
                              I mean had he indeed found a way to extract 10KW out of that, why is he not presenting it with lighting hundreds of bulbs rather than playing with plasma?

                              But i will experiment with that stuff too a bit soon to see it for myself and not only being skeptical.

                                I couldn't find the book from d'Arsonval in french that Don Smith cited in his 1996 lecture



                                but found an English version of a book "Medical Electricity", from 1916 talking about d'Arsonval medical device.

                                Scanned in 2004, all pages are available for free by Jeff Behary c/o "The Turn Of The Century Electrotherapy Museum"
                                The great website : The Turn Of The Century Electrotherapy Museum Tesla Library

                                Index of the book : (1200 pages, 160Mo of .jpg)

                                Hope you can find useful data inside,
                                thanks and good luck.
