    Preliminary test, or preluminary test, of the secondary coils alone with "offline" transmission through a bucket of soil and directly connected coils, or set up as a single wire audio system. The (much better) 22mm diameter copper pipes that were used in the bucket are now buried in the garden so the 6mm diameter steel rods will have to do in the meantime. The same modulating preamp as before is used as the power supply with no modifications. Ohm's law has fallen overboard.

    From the video I remember that this single wire transmission works with 8 micron wire while a normal power transmission line has to be 16mm2 for this amount of power transport.

    I try to understand Tesla/Eric in saying that the energy is transported through an electrostatic longitudinal wave in stead of a transversal electromagnetic wave. I suppose that the transversal wave modes cancel each other in this transmission line. The line really acts as a wave guide and they say it is much more efficient than an circuit exactly like Tesla wrote.

    I can only think of lines of force going from one part of the wire to a part that has a lower potential further on the wire because of some resistance in the wire gradually lowering the potential along the wire. I hope I picture this right?

    I don't think it's necessary with the extra coil, at its ground end there is the secondary's gradient ring, and on the top end is the capacitance mast. Unless you are talking about the copper mass? I have a problem already in that Tesla's measurements were not accurate due to stray factors, so my frequency is already higher than the designed scaled frequency because the stray factors don't exist in my setup. So you could say that the unwanted capacitance is already "missing".

    Thanks for the concern but I am informed and the knowledge has already served its purpose. There comes a point that you can (want to) be no more informed and the information serves only as a distraction. You will find enough "information" out there to keep you occupied for the rest of your life, posted all over youtube no less. Beyond the basic truth it's all useless and quickly leaves the realms of reality behind. It's time to move on and do something productive, otherwise it makes no difference whether you are informed or not.

    I agree Eric, that is the reality of it.

    I was referring to the words and reality post, which appears to now be
    completely replaced.

    Minor adjustments will be made but the primary and secondary coils are now good to go:



    The extra coil parts will be assembled and wound over the next few days.

    Nice Sunny Lyrics dR-Green, I like it !!

    Tesla complex currently do nothing !! Wait new investments and young fresh minds to continue Tesla work !!

    Couple of photos from Tesla towers complex near the Town Истра, besides the village Красная Горка.








    From this Tesla tower were lauched the biggest manmade sparks ever, more than 150 meter in lenght - more than 500 feet.

    Very impressive. But what does it do?

    Not all the statements attributed to Tesla are really his. And, the "key" can also be in Russia or Madagascar. USA is not special in any way. Give scientists from other countries half of the standard of living that Americans enjoyed for decades and they will probably be as creative if not more. Gens una sumus.

    Looking at your secondaries, did you intentionally increase the inter-turn spacing towards the top of the coils to better distribute the voltage gradient? That's an excellent idea, I hadn't thought of that. Does that eliminate the need for a gradient ring? It makes sense to do it that way since max current will be at the bottom of the coil and max voltage at the top. I wonder how that effects the velocity of propagation?
    Yes that was intentional (but it was originally only meant to be the top 2 turns not 3). I copied and scaled the frame dimensions (groove distribution) from CS Notes rather than just the coil (winding) dimensions. The final turn is the one described by Tesla as being "on insulators", and on my coils is a thicker wire than the rest of the secondary, so it also plays a similar role to the gradient ring, but the main reason it's a thicker wire is to match the copper mass to the primary.

    Tesla says the final turn is excluded from his (L and C) calculations, but including or excluding this changes the height of the coil (and the free space propagation), so I haven't investigated exactly what's going on there yet. At this point I don't know if I should include it or exclude it to get the free space propagation, and I don't have any reference to know any different what effect it all has on the bench. Only:

    Free space propagation (excluding final turn in coil height) = 68%
    Measured propagation (including final turn) = 63.19%


    Also, thanks for the updates Aaron.
