Nice coil !!! But i do think you may encounter problems with the plastic insulation .  It may restrict the water from doing its thing.  Ive noticed that makes a huge diff.. And as far as putting thread between it is a pain in the arse and i don't recommend it.  I do recommend the cotton/cloth sheath or tubing from the diy audio store or that other place sid posted. The effect is more pronounced when the iron/steel is exposed . It may be insulated but i wouldn't do plastics or acrylics.   Hope this helps a bit. Thanks for your hard work again.

Just messing around with a reed and trying to pulse it with a spinning coil.  My cell is almost completely dry so its not putting out barely any measurable power.  Just having some fun.

G'day all,

@Freezer:  That's a pretty smick piece of engineering you've got there, good work!

@Georgemay: I not sure if this will work , It is just a thought. How about putting your coil in an electrolyte and just using  the iron coil ( copper not connected to anything)  as one electrode and a separate piece of ferrous metal as another and try and electroplate the oxide layer away from your coil.
It may be a way of cleaning up the coil without disturbing the whole assembly.
Anyway as I said it was just a thought. Good luck with it dude.

Ian,

The coil is in pieces.  I am cleaning the wire now.

LocalJoe.

The 'plastic insulation'  I have is a see through mesh.  Actually you can see the wire.  Water runs through the coil like there is nothing there.  It may not retain water like cotton insulation does.   Anyway the wick is on the order.

Sorry i didnt realize that about the mesh but ... The second reason im sticking with the cloth is just what you have mentioned. The cloth insulation will act as a siv in moist ground and retain a certian level of moisture. just enough to energize the coil. This guy was clever for his day.
