NO JOY

Shell condenser   Testing brings no joy.

It appears that I have a major error in the coil lay out design.

The outer ring of the disk seems to be a short in the field that limits the rim to 485vac instead of the 80,000 that I was aiming for. The design of the coils was for a 600 volt per turn field. 485 volts is about right for the coils fully loaded sag.

Tesla remarked in his “Boulder Colorado Notes” that with air coils, any 3rd coil aligned with and within the influance of the primary field would react with the same per turn voltage as the primary.

Note that this drawing of Tesla’s transmitter, the top toroid is covered with dimples. In the Wycliffe design the dome was covered with “scales” that did not touch but were connected in a star pattern at the center of each panel to prevent current circulation.

Pictorial schematic 03

Guess I should have paid better attention.

My present layout has all the power coils in axial alignment with the disk.  The skin of the disk acts as a short.

The naked main coil would light up florescent tubes 3 feet away.  The unpainted Disk over the coil limited the tubes lighting up to about 6 inches. The metal paint seems to be preventing enough radiation to cause any light up of the tubes. To solve this problem all the coils will be removed and used remotely for testing while a new coil system is designed.

A poly phase coil driver set is contemplated.  Most likely star configured and laid out axially between the frames 90 degrees from the disk axis.  pg

    This is a bummer, pg. I’d thought you’d separated the conductive areas to avoid the eddy currents. I hope your rework fixes the problem.

    The concept that the skin of the disk would serve as a “coil turn” seems to have escaped me. 😦
    However “no big thing”. This coil layout was just a test setup on the way to the conclusion.
    Unlike my first attempt, this one is made up of parts that can be changed, rearranged, or replaced as needed. For now the Great coil and it’s driver will be removed and set up nearby, 90 degrees off of the shell axis, to remotely supply high voltage to the disk for additional testing. This will also make several other experiments easier to carry out.
    Next I will need 3 high voltage coils that can be driven polyphase and arranged in a star pattern between the disk frames, 90 degrees off of the disk axis. If that works the thrust cans will be next. 😎 pg

    pg – since I was never really into Tesla coils it took a while to understand the advantages and problems of the loose coupling that they use. It allows lower turns ratio, but the magnetic flux does spread a long way so there are a lot of side effects running both ways. I don’t think that the loose coupling does anything other than that, though – using a cored coil where the core is fast enough would work just as well as regards the final results and would be a bit more defined. Maybe worth thinking about if you need to get the coils close to the conductive plane of the disk in future. You can invert the normal construction and clip the ferrite (as TV yoke coil cores or similar) around the coils so that the ferrite is wrapped around the wire rather than the other way round. One way of getting bigger coils and still reducing the stray flux. Since this gives tighter coupling you’d need a higher turns ratio to achieve the same voltage hike. It might be more efficient, though. By changing the number of ferrites clipped on you can change the coupling and the shielding.

    @Simon; Thanks for the insight on enhancing coil coupling and shielding. My knowledge and experience is mostly in electrical and not electronics. This thing is an electronic project on a massive scale of energies. Kind of like a CRT based display the size of a house! 😎 pg

    pg – I’d also thought to test out the plastic-coated soft iron wire used in gardening as the core material to wrap around a coil to improve coupling and shielding. It may not go to the same frequencies as ferrites, but is cheap, easily available and easy to use. There’s however no specification as to the saturation level in it, core losses etc., so it’s a bit suck-it-and-see to decide how much you need to use. We can make some estimates, though, from the characteristics of pure iron since it’s pretty pure without much alloying (otherwise it would break too easily when wrapping plants). Insulate the ends of each length of wire from each other so you don’t get an electrical loop. Ideally you’d go for a lot of C-shaped sections with an insulated small gap between the ends, but a lot of small lengths with a few wraps would be OK unless you had very high frequency.

    Note that I haven’t tried this myself, but worked out the idea when I wanted some special-purpose coils in another experiment – how to stop the big magnetic pulse getting out of the box. Somewhat of a poor-man’s very-large ferroxcube fully-shielded core. Because the iron wire is thin and there’s the insulation around it, it should have low eddy-loss and be good to around 10kHz (but I haven’t tested it).

    pg – there may be some interesting reading for you based from http://revolution-green.com/displacement-field-drive/ which one of our audience noticed. It’s very much a different principle than you’ve been working on, but currently they can produce about an ounce weight of force.

    @Simon; The spinning diamagnetic disk over a stationary Hv disk should yield the needed result.
    Reduction of the effects of mass/inertia and gravity.

    My attempts are designed around achieving the same results by different methods.
    The use of high voltage and elevated frequency fields in rotation. My WAG is 80,000volts @ 20,000 cycles in rotation. One gravity equals about 60 horse power on 1000 pounds. One “G” of acceleration will result in “Trans Light Speed” in 40 days.

    A number of years ago there was a “craze” over ceramic super conductors that would work at elevated temperatures.
    Two researchers in Finland published a small paper in the German edition of “Nature”. that reported strange results from their super conductor experiments.
    They created a 10cm disk and placed it over a solenoid inside a set of poly-phase coils. The solenoid levitated the disk and the poly-phase coils were used to spin it. This was in an open flask of liquid nitrogen for the needed cooling. As the apparatus was operated the pipe smoker noticed that his pipe smoke spiraled UP and not Down over the super chilled flask as was normal. The experiment was being carried out in a multi floor building so he checked on the floor above and below, in both cases his pipe smoke spiraled UP in the area above and below the experiment. Changes in the frequency applied to the apparatus changed the amount of the effect. His estimate was a 3 to 5% reduction in gravitational effects that was being caused by the spinning levitated super conductor disk. Super conductor ceramic material acts as a diamagnetic material, as it reflects any magnetic lines of force that attempt to enter it.
    There was supposed to be a more extensive paper in the English version of “Nature” but it was never published. A few years later the Russians claimed that they were the ones that did the experiment, not the Finns. One of the Finnish researchers named later claimed he was not involved.
    This one of many reports of strange effects resulting from spinning EMF fields. High Voltage fields as well as those at high frequencies also seem to result in effects not expected.

    There is much more to learn about physics then is presently accepted in the standard model. pg

    pg – in the situation you mentioned it’s a little difficult to be sure that the effect is a reduction of gravity or is an effect of diamagnetism or something else. If your disc shows an effect, although you’ll be pleased and think your theory is justified you still can’t be really sure that it’s not pushing against *something else* and not a reduction of gravity. In fact a thrust independent of gravity would be more useful since it would work outside a gravitational field.

    I think gravity is an effect that is caused by mass slowing time down (and not time being slowed by gravity) and thus it seems unlikely we can actually produce a variation of it, but a device that produces an electric/magnetic field and pushes against it to produce thrust should be possible and also very useful.

    I’m sure there will be a lot more to learn, anyway, and making sense of the experimental results is going to be fun.

    @Simon; whether the effects are gravitational or inertial, we can let the Phds determine later after we make it work. 😉
    I my opinion, mass/inertia and gravity are all effects of warpage in the Aether created by EMF emitted by matter. As they are all connected any modification of one will affect the others and act as propulsion, much as a helicopter “beats the air into submission,” the active fields will get a grip on the Aether. pg
