Question of the Day
Question:
"Dr. Hal, I think my lawn mower is sending me messages. Since it doesn't have a battery like a car does, then where does the electricity to spark the spark plug come from?"Answer:
Most small lawn mowers, chain saws, trimmers and other small gasoline engines require no battery. Instead, they generate the power for the spark plug by using a magneto. Magnetos are also used on many small airplanes-- because they're extremely reliable. Now, the idea behind any ignition system is to generate an extremely high voltage, on the order of 20,000 volts -- at exactly the right time. This is Power Tool Drag Racing kind of stuff. The voltage causes a spark to jump across the spark plug's gap, and the spark ignites the fuel in the engine. In a magneto, a strong magnet is moved past a coil of wire to generate electricity. In your case, the leaking electric pulses through the handle of your mower deliver the so-called "messages" in sympathetic resonance to the sinusoidal nature of your nervous system experienced as feedback to the brain. It happens when within the magneto, a magnetic field having been generated in the armature, inducing current in the primary and secondary coil, and now reaching its maximum, a switch in the electronic control unit opens. This breaks the flow of current through the primary coil and causes a voltage spike of, perhaps, 200 volts (I'm not familiar with the specific anatomy of your mower). At this instant the secondary coil, having 100 times more turns than the primary coil, which it's wrapped around, amplifies this voltage, in one tremendous surge, to 20,000 volts-- and this voltage feeds to the spark plug. Of course, in your case you are indeed, as you have accurately suspected, receiving esoteric communications in this fashion, though I won't elaborate here. Just follow the instructions I gave you, and all may be well.
