Waterfuelcell resonance action discoverd

what type of current probe are you using?

Thats the only thing i dont have, newguy. Only basic probes and 1 HV probe.
Maybe i can make a current probe with a coil or something.

we gotta have a current probe, been needing one myself

Steve,your seeing a resonance ring for sure.Have you checked the generator by its self without the cell hooked up?This may tell you if it's just the generator.Other wise,thats the frequency your cell is resonating at.Your seeing a ring just as if you were doing a hammer test on hydraulics.You can see the same effect in Spice also.

Try a Different Gap size, a single cell. See how this effects your Amplitude, Add salt, Did it effect the amplitude?

Simple test, Simple answer.

Try a long tube, Try a short one, Try even a Plate, Try 3. Remove the Water stevie, Use Baby oil. Any change?

Where must this Ringing be coming from? This ringing is a sign of something that is at resonance for a short periode, We all know there is no Perpetual resonance. Get to the bottom of it. I also got this same wave form with chokes when i first got an oscilliscope, However i didn't pay any attention to it and it never got my attention, I figured since i was using chokes, that it was just the chokes ringing. However, you didn't use chokes so,, I'm kinda interested now in where this ringing might be coming from!

the only thing i can think of is maybe the cell took on some charge, then there is a resistive resonant discharge happening.. during off time.. 

 i was sitting next to a piece of heavy equipment the other day the bucket was off the ground like 4 feet.. tractor was off.. its a older tractor and doesnt have the best performance.. leaky hydraulics... anyways sitting there i could hear a popping noise of the buckets joints because the hydralic cylinder was slowy leaking..  every little pop noise the bucket would drop a hair.. the point of this story is it would go into resonance.. meaning the pops would happen every 4 seconds or so... the bucket in the air is equivalent to potential charge that is built up.. the slow leaky discharge is eqivalent to resistive discharge... it will always tune into its own pace (resonance) of discharge determind buy the weight, height and malfunction of the hydraulics.

Ok,

I just removed the wfc from the circuit/FET.
So circuit, without load.

Now there are still some ringings. Less high and less impressive.
The scope setting are not changed between the 2 pictures here.
The big ringing thing is WITH my waterfuelcell.
It puzzles me a bit.

Measure between the gate and ground of the fet, see what that shows. I remember, They use to use the 2n3055's and take them apart, They would use them for some sorta Energy generator like a solar cell, Or, it could have been a Thermo Generator. I forgot.

It is less impressive because the fet is not under load. Remember how it wasn't so easy to get the alternator to go into loop mode, There must be some conduction before the fet will work properly. If you was to replace certon Loads, with Say a Led Light running to a fet, "It is possible the Led will not be conductive enough to cause the fet to kick on." This is why it is more impressive with the wfc, or load.

I will do some measuring on the gate. I also will do this test with 2n3055 transistors and see what that brings.
