Bismuth core Joule thief

You got it , just imagine a 3 layer sandwich bismuth (modified to be  a solid electrolyte) so it could be aluminum /bismuth (electrolyte/reactor)/ carbon plate turned into a coil think tpu size coil , then put a coil around it(secondary) and a switching device on the coil to kick it.

Do  you have any links  for this bismuth electrolite ?

Are you talking about using  carbon  like it is a plate in a battery?
If you  can find  a way to support it .......you should  be able to pour melted bismuth around a carbon fiber core.....or maybe a spiral .

Take your pick there will be some chemistry involved in the process , but it is already used in fuel cells , they work on fuel , we could use magnetism to power this one like the NS .

RotoMetals sells bismuth.

I've acquired a pound of it (99.9% pure),  It's very wacky looking stuff, ..there are veins in it - shard like.  Very different from lead.  I've tried to stay away from lead.

.. I'm going to make a mold of plaster out of a toroid and see how this works out, I'll probably try a smaller toroid, and duplicate the circuit, one with the bismuth and one without ( from the original toroid  obviously ).

This may take a few days, I'm currently busy.  I may need a better torch too.

Edit:  I'll probably have some of the work done by Wednesday.  I'm a bit pre-occupied lately.  On top of that I'm having PC issues.

Ok, so far I've messed up three molds, I'm probably going to have to rethink this a bit.

On top of this, I've had some fiscal problems lately, And foresee being pre-occupied for a very longs time.
