Captret - Capacitor and Electret

[Sprocket]

@Groundloop - Guess I should have read more of the thread before posting (I assume this had already been posted) - that's quite intriguing!

For the record, using a 1000uF cap, after shorting and about 5 sec, the voltage is already over 0.1V, after about 30sec it is over 0.13V, using a digital meter, so despite the 10Meg loading.

I also noticed that the rate of change is temperature-dependent - grasping the capacitor tightly in your (warm) hand sees the voltage shoot up, (relatively speaking!) release it and it falls back down again.  Interesting...

Ok, you don't need to put salt into it you only need water. Salt might corrode the aluminium foil. Thanks electricity!

The newest captret has a smaller negative on the outside and about the same size positive in the middle. The captret part is bigger then both. The voltage in battery is 5.38 volts, but negative to captret it goes up to 5.50 volts. So the bigger the captret foil and the smaller the negative and positive the higher the voltage.

This could be where the self charging is coming from, because you need higher voltage to charge and thats what the captret is doing.

You may find that it's more pressure dependent than temperature. Try the same experiment again but eliminate temp from the equation either by insulating your hand or use an alternate pressure method.

Hi everyone! 

how about pulsing a tiny coil with this captret?
i'm looking for a strong self induce energy and charge the battery.

just a wild think 

great discovery 

I think Tom bearden has a version of this discovery too.

i hope this vid will help us a little, some kind of a little related.

I have held it in a small vice and blew on it and the voltage also went up, stopped and it fell - that could be moisture-related but I think it has more to do with temp.

Anyway it's a moot point methinks - after trying a few more caps I found to my horror that the 'effect' is only really relevant with a single one, all others climb to a measly 20-30mV. Sooo...  I spent the last hour  desoldering a dozen or so more from a bust TV set - result, nada, zero, zip.  They all at most increase to 20-30mV...

So I have just ONE cap that shoots up to 140mV, all the rest, nothing!  I'm discouraged...
