oooh, good point, I never really came across anyones documentation on the carbonizing of oil. Im curious what would be the minimum requirement for this to not be a problem. I had some thoughts earlier on mixing Tesla's flat disc viscosity turbine with the rotary spark gap to create some motion in the oil, but then I lost some heart with the complexities of controlling a motor and all its moving parts alongside the complexities of timing and whatnot. Really can't beat the simplicity of a multi spark-gap!

Upon your note of the resonant charging circuit and seeing how simplistic Tesla's circuit evolution descriptions were, I am very interested in hearing more about your expensive lessons on resonant charging! I would love to do away with heavy iron in these desktop designs. Another trademark testament to the importance of understanding "tuning"!

I caused some good curiosity with my Grandpa this Thanksgiving when showing him my illustration work on Teslas 1981 lecture (that you and I have talked about earlier this year), and he asked me if I could build him a high frequency oscillator for his office. I would love to send him something that doesn't require 20lbs of iron and oil for powerful and beautiful operation :D as for my office as well. Yes!
