Stan Meyer's pencil math, 1987: five miles of wire in one coil

Five pages in Stan Meyer's own pencil, signed "Meyer 1987": the arithmetic behind his voltage intensifier circuit. The secondary is 84,500 turns of .002 in copper, 26,000 feet of wire, almost five miles on one spool. Divide by the 200-turn primary and you get a ratio of 422.5: twelve volts in, 5,070

Five pages in Stan Meyer's own pencil, signed "Meyer 1987": the arithmetic behind his voltage intensifier circuit. The secondary is 84,500 turns of .002 in copper, 26,000 feet of wire, almost five miles on one spool. Divide by the 200-turn primary and you get a ratio of 422.5: twelve volts in, 5,070 out. The chokes are 430 stainless, a resistive wire, and he worked out its resistance by hand, 16.33 ohms a foot, which is what the book value gives. All five pages, with every number transcribed and checked, are on stanslegacy.com. Wind one and tell us what you measure.

About the voices. The narrator is NeuralStan, an AI voice the archive uses for its made films. Where you hear Stan Meyer, it is Stan: every word of his is cut from an original recording, and nothing he says was synthesised.
