Recently I have been reading about a thing called the Tesla hairpin circuit, or the stout copper bars arrangement. I have never heard of this before in over twenty years of Tesla research and *fiddling*.
Best I can find is something to do with radiant energy and, it would seem, a short form of wireless power transmission.
Have you heard of this description, and if so can you direct me to simple plans and explanation of the concept.
Beers and cheers,
