We’ve thrown lots of sparks, but is that all Tesla had in mind? In this sequel to the classic, we venture into the utilitarian Tesla. Can Tesla coils do real work? Can they power an alternative fluorescent lighting? Build a “third generation” Testa coil and a Tesla lighting plant. Discover the magic of oil immersion, close coupling, and precise pulsing. Meet the new electronic neon technology. A look at the familiar hybrid-spark ignition-coil and flyback Tesla coils. Then a leap forward to the Tesla coil pulsed directly by solid state, where battery 12 volts can yield a clean usable output of 2000. The same circuitry can pulse 500 volts into a primary, yielding 100 times that. Can spark also deliver clean, stable outputs? Meet the Chaffee gap. 40 illustrations.
