Hi  :)

nice work hydro, could try applying pulses to a length of aluminum wire (ace carries it, clothesline wire)
 in the pic i have a 40 watt bulb being lit, albeit dimly,  using a fet and 555 it captures the emf more
 effectively than all of the materials I have used (copper, iron)  each coil has it,s resonance and this coil
 is short, I,ll guess that a longer one will have "bigger" capture of the spike.

Edit: I,m using a 12 volt battery as the power supply

your post is a little confusing. when you said you used a 12 volt power supply did this mean you used that to drive the fet, or did you use that to replace the wfc?

let me get this straight, you are using the back emf from a fuel cell like i have in the picture?

thanks genx, i will look into that wire, what is ace? maybe the ladie will know.

Hi Hydro

It,s just a straight hookup to the battery, I guess the point of the post is the aluminum wire has the best
 kickback potential, I haven,t tried bifilar yet.  I couldn,t find a place to put the post so I stuck it here, if you
 have a better spot than point me to it and i,ll put it there.

thanks for the site

Ok,

Today i tested this schematic.
It was part of a series of tests, just to see what Back EMF can do for any good here.
It was also because I saw some videos that put me on some thinking paths.

Test equipment:
555 timer with a very low frequency (1 till 20 Hz)
1 dpdt relais
1 solid state relais
normal LEDs
1 MOT (trafo from microwave)
And many other coils from personal collection.... ;)
Of course, my scopes and multimeters

My results are :
The test described by Wouter's message is correct. You can add BEMF into a capacitor.
Its scarry to see the voltage go to levels beyond the level of my battery....
From a 12V battery to 140V into my test capacitor.
That was a great test!
I also tried to discharge the capacitor into a very little test cell....
I am sorry to say that really nothing happened...LOL
Maybe the frequency of charging and discharging was tooooooo low. (every 20 seconds)

Hydros test:
The test with the schematic of Hydrocars also works. I can see a LED burning almost constantly.
However, I must say that I was hoping for more electrons to take out of the WFC.
I think the reason was as follows:
I saw some very very high voltage peaks on my scope. Hundreds of volts!
After a discussion with our master chief HYdrocars, we where from opinion that the BEMF was the reason of these peaks and that my relais between the coil and wfc was TOO SLOW.
If my relais reaction was quicker, I should not see the high peaks, because of the resistance of the WfC.
The BEMF was gone before it could hit my WFC.
Hmmmmmmm, that was nice and not nice. So, and old tyoe relais is too slow.
I also have now 2 Solid state relais in my collection.
As soon as i am more familiar with these kind of relais, I will do this test again , if necessary.

Every body the best with testing.
Till next update!

i hooked the cell to the primary side of the mot and the output was great!!!! allthough it would not light a floresent light you could still see deadly blue sparks. in this setup the fet made it possible for the wfc to run the trafo. i did try to put the tranfos output back into its input, it did resonate and slowly die, i think the problem with it not resonating to infinity or something is due to the SS tubes, i think they should be nickel coated before it will work.

to bad im not taking any further, right now i have other fish to fry.

The problem with SS relays is that there is some amount of leakage current so they are rarely completely off. In addition, they are voltage limited so if you've got really high voltage transients, they will probably short out fairly soon depending on their voltage rating.
