Alternator Rewire (Y-Configuration)
The second image is taken from Stanley Meyers' Patent on his Water Fuel Cell. The first image is my re-drawing of his schematic. It is an image of a car alternator, from which the diodes and voltage-regulator have been removed, with new circuitry attached. The three pairs of concentric circles are the stainless steel electrolysis electrodes. The three coils forming a Y in the center are the Stator. There are two ways to wire up a three-phase generator: Delta, and Y. This is for Y configuration. In a Delta configuration, the coils form a triangle.
The Rotor spins inside the Stator. Normally, in your car, a voltage is maintained on the Rotor coil, so that whatever RPM your engine is running at, the voltage induced in the Stator coils is a certain voltage (13.6 V?). Stan Meyers rewired an alternator so it would produce pulsed DC for electrolysis. He was feeding the Rotor coil a pulsed DC waveform which I have drawn at the bottom of the picture. As you can see, the wave is "Gated", or has a Duty Cycle of less than 100%. Waves like this are easy to generate with two 555 chips, where one is set to a high frequency, and the other a low frequency. The low frequency oscillator Gates the high frequency one. You can look at the waveform in the picture as a high frequency wave, which has been amplitude-modulated by a low frequency wave.
Dave Lawton published a simplified circuit based on Stan Meyers design.
