Leo discovered how power circuits work. He says smoke is the real thing that makes power circuits work because every time you let smoke out of something electrical, it quits working. He claims to have verified this with thorough testing.
Smoke makes all things that are electrical work.
I sat and smiled like an idiot as more of the truth dawned. I remembered when I'd witnessed the awful destruction of a four-kilovolt breaker and bus at Sunnyvale. The breaker and bus had leaked out so much smoke that they actually melted and quit working. See, it's the conductor that carries the smoke from one device to another. It starts at a power plant where the stuff is burned to produce smoke.
