  • Helmholtz resonators as WFC?

    Just wondering if anyone has ever used Helmholtz resonators (shaped like a gourd) as their WFC. If not, why not?

    A Helmholtz resonator is a single-DOF narrow-band device. It should be easier to build-to-tune to one specific frequency than a set of nested pipes. You'd have a metal gourd-shaped WFC with a single wire center electrode so you get that large voltage gradient near that wire.

    I view the water dissociation setup (and correct me if I'm wrong) as two resonators pinging back and forth between each other. One resonator is an LC circuit, the other is the WFC itself. Both of them have to be at a specific resonant frequency or heterodyning will take place, and you won't get that additive power accumulation from resonance.

    So your circuitry has to be free of extraneous noise, and your WFC has to be narrow-band.

    Or am I off in left field again?

    Another question... this regards charging the WFC "capacitor"... why do people push their voltage *and* their frequency in at the same time? Shouldn't the voltage be applied all the time so the cap can stay charged, and the frequency is arrived at by pulsing the return route?

    Take two scenarios:
    1) A WFC is at 0 volts. We hit it with 20,000 volts at 42,800 Hz. The WFC has to wait for each pulse before it can recharge.

    2) A WFC is direct connected to the high voltage source (because of the resonance driving voltage high and current low), and charges to 20,000 volts. Then, the circuitry pulses the voltage return path at 42,800 Hz.

    Keep the WFC "cap" charged all the time, only pulse the return path, which would cause a gigantic and instantaneous voltage gradient at the electrode far in excess of what your power supply could do when filling the "cap" under Scenario 1.

    Would that make any difference? Or am I TOMA again?

      Ok, last dumb question for the day... I promise. Heh.

      Is it possible to drive voltage so negative that you're below the entropy of ZPE, and thus ZPE will *want* to flow into your circuit? Or is that how it even works?

        Ok, I lied. One more dumb question. LOL

        Has anyone ever tried to use piezoelectric transformers to provide the high voltage at high frequency?
