  • Modifying a tesla coil to produce longitudinal waves

    I thought I would start this thread as there doesn't seem to be a dedicated source to this topic despite the interest in the production of such waves. Also, there is a device that I read about many years ago called the Perry Interdimensional Power System that I would like to attempt to replicate one day which uses a tesla coil:

    Perry's Interdimensional Power System - KeelyNet 12/23/01

    The device uses a tesla coil that limits radiation of hertzian waves. Above the coil are two copper plates rotated at 20,000 rpm, between which is a flat spiral coil. Mounted on the outside of the copper plates are magnets used for shaping the field generated by the rotating copper plates. The inventor of the device claimed that with a 100 watt input he was able to obtain a 350 watt output. The inventor of the device died a few years later under mysterious circumstances. This is the only information that I can I find on device. Based upon what I know about tesla coils and judging from the power input I would assume that the device uses a solid state tesla coil, although considering the large box holding the coil it could be a small TMT.

    My understanding of modifying a tesla coil to produce longitudinal waves is that the production of such waves is best achieved with a three coil system in which the tertiary coil is wound with loosely coupled turns and the topload is of very small capacitance, while the input to the primary coil should ideally be made up of non continuous transients such as impluse or oscillating currents. However, assuming that the tesla coil used in Perry's system is solid state this would contradict this. There are also other experimenters such as Stoyan Sarg who use soild state tesla coils for longitudinal wave production in their experiments.

    So basically my question is can any tesla coil be modified to produce longitudinal waves and if so what modifications need to be done to the coil?

    its not readily obvious but look at the size of that first coil



    until you run across this pic



    the coils seem to have a deliberate distributed capacitance, I expect similar to eric dollards transmission line experiment






    I get the impression that the most efficiency is obtained when the magnetic and dielectric is at the top of the coil at the sphere and the whole circuit is a 1/4 wave funnel.

      The problem is that amount of power produced in longitudinal wave is miniscule. Why I stated that ? Because in other ways we would have longitudinal effects everytime we turned on the light switch. It required HV voltage and a device to switch it ? do you have such ? All mosfets I know is restricted to some 800V .

        I've been very interested in producing longitudinal waves from a Tesla coil myself. I've tried numerous different types of input to a standard tesla coil configuration, including pulsed dc, even going so far as using the pulsed dc from the exploding water experiments with an ignition coil. Everything I did seemed to produce standard hertzian oscillations in the Tesla coil. However, I'm not sure how you would necessarily measure success. Part of the problem may be identifying the production of scalar waves, unless produced in really large amounts where there are noticeably odd effects.

          MEYL uses 4 to 90 ratio on a pcb. About 6" dia sec pancake coil on top and about 3x space to trace ratio and for secondary and the primary on the bottom of the pcb with 4x spacing and 2wice the path width of the sec coil traces roughly.

          He shows the tw and lw waves in his demo.

          dollard appears to look at it like a transmission line and he shows how to measure the magnetic and dielectric so you can use that to adjust your coil.

          Then finally I would think there has to be a 1/4 wave standing wave between the source and the sphere.

            I was surprised recently to see Dr. Lindemann's comment that he didn't feel what Konstantin Meyl was doing was the same as what Tesla and Eric Dollard were doing. I can't remember if he also said that he didn't believe that the apparatus that Meyl was using actually produced longitudinal waves or if maybe I just assumed that by extension. Either way, I would like to see an elaboration of the point by Dr. Lindemann, which I'm sure he has done somewhere, I just don't know where to find it.

              Is this the one?

              If you really want to replicate Tesla's work, you should study the work of ERIC DOLLARD, who is the only person in the last 30 years to have built a Magnifying Transmitter. In my opinion, all the work of J.L. Naudin and Konstantin Meyl is unrelated to what Tesla was doing.

                Ha,ha!! Yes, there it is! For the life of me, I couldn't remember where I had seen that statement, and there it was in a thread right on this page! Thanks! Oh, by the way that last post was my first post here. Forgot to mention that. Been lurking for a while.... Howdy all!
