Carbon Arc Spark Gap COP Calculation
magnetoelastic:
For example, I can measure the output voltage of an unloaded neon sign transformer. Then, by adding a capacitor of a few hundred pF, across the output, I can measure the output voltage to have significantly increased. If I assume that the Ein is constant in this case, I can conclude that the capacitor is OU, where, in reality, it is just resonating with leakage inductance of the transformer to allow the AC mains voltage to more effectively deliver Ein.
Elvis Oswald:
I have to agree with Magneto (partially) on this one. But keep in mind that no one is shooting anything down... this forum is heavily "peppered" with tangents that are counter-productive - caused by the inability to see that asking questions is the very heart of experimentation.
To whodini - Showing more energy out with one circuit compared to another proves only one thing for certain - efficiency. Quesitons that seek to validate the amount of energy in are valid... But, something I've discovered is that no matter how you measure it... it will never be good enough for some. :)
Personally - I believe the coincidence is too great. Energy is all around us - witness lightning. And what is a spark gap, but lightning? A potential difference creates the path in the air gap via ionization... just like streamers in a lightning storm. You are definitely on to something.
To Magneto - a WH Gen. is not the same as a transformer connected to the grid. The comparison is apples to oranges. But - I'd like to hear some basis for the argument that the circuit is simply pulling more power from the WH. Maybe you can give us insight on how to ensure equal input to both circuits?
Elvis Oswald:
Why not charge the capacitor with the generator... and then move that charge through the test circuits and measure the result? That would ensure the Ein was the same for both circuits. Should be simple (and satisfying one way or the other) to all.
magnetoelastic:
I would also suggest a few modifications to the experiment - try to determine if it is the carbon/tungsten combination that produces your boost in output, or just the spark gap. Substitute your carbon rod and/or tungsten rod with a different material, say, brass or stainless steel, and see how that affects your result.
To measure Ein, you would probably need to place a torquemeter on the WM. The torque needed to turn it will be a function of its power output (though I am guessing the WM efficiency is VERY low).
Doctor Whodini:
My proof is the difference in output energy. Thats what counts.
