Has anyone tried to build a TMT (extra coil) Tesla coil?
« on: April 16, 2024, 09:21:39 PM »
https://waveguide.blog/history-tesla-coil-geometries/

This article goes into some detail about it. Tesla seemed to think the third “freely resonating” coil could make “bigger sparks”

Googling this comes up with basically nothing. Was this idea lost? Impractical? A bad idea?

Tesla said it will “be recognized later as a material and beautiful advance in the art”

There are also a bunch of cone Tesla coils he built. Makes me wonder what other unexplored coil geometry might work. In another thread I mentioned I’m going to try different geometries because it’s fun to build secondaries but I need to figure out how to make some self tuning drivers that I can hook up to different coils for testing.

They are usually called "magnifiers" for some reason. People still occasionally build them but it seems that they are needlessly complex and take up more space than standard 2-coil designs. I haven't seen any evidence that they out-perform standard 2-coil designs.

Thanks for that key piece of info lol.

Now that I have something to go off of I have found more information. I even found a thread you posted with an interesting paper about this, that nobody replied to sadly. The paper talks about people continually copying old ideas which really resonates with me no pun intended. I intend to do weird stuff with tesla coils, or maybe I'm not smart enough to know what's a bad idea. At least I'll probably try something nobody has seen before, maybe someone will be entertained by it. I will investigate this extra coil further and see if there's anything to it.

Tesla himself had some interesting theories but of course it's hard to separate the fantastical from the practical; however I am inclined to wonder about things he insists upon based on his track record of innovation, even though a lot of his ideas were proven to be bunk.

Thanks.
