I wouldn't know, I can only surmise, if I said they were at different stages of an experiment, I think that would be incorrect
As the displayed items are as a display, it suggests to me the intension is to show the different stages of the cells construction.

Aside from the above photo, as I mentioned previously, the material I have has been made on a laser printer, some of it is very old, some photos are in a bad state, tonight I have seen the perfect example privately emailed to me, so if anyone has better copies than the ones I have, please post them as better copies are able to tell us more info.

Finally started my replication and took some photos. The cotton tubing is from wickstore. 1/16"

http://www.wickstore.com/wetbulbwick.html

Copper is 2mm 12M
Bare Galvanized wire 1.9mm 12M

I used a cotton shirt for the insulation of the and each layer of winding and made careful there were no shorts between the galvanized wire. The wire ended up at the other end of the coil than what I started. Shouldn't make a difference though. If I don't get any results from this, I can just splice on more wire and wind probably another 15-20M.

Will start testing the coil dry and wet tonight.

I added another nut on the inner part of the coil and also a washer so I could tighten down good the wood end since I would use it for turning. The other end fixes itself. I attached the wires to the coil first and then pulled as tight as possible by holding onto the wooden ends of the coil and turning and keeping the wires tight at the same time. The other ends of the wire were 12M away attached to a wall about 1M separated so I could vary where I stood to make sure each wire was equally tight. I wanted to make sure the coil was as tight as possible to increase the voltaic response. Definitely want to motorize this for next test!! I have a slow speed drill press that I think will work good.

The rest?

Did some testing using a extech 22-816 rms multimeter

All 4 wires open, coil dry
.801 volts dc (positive probe on copper, negative on iron (same end))
0mA

Immersed in spring water
.942
0mA

Not sure if those are good results. Will test tomorrow to see if it's enough to drive the nc reed switch. If I need to add more to the primary, I have more room and can just splice in more wire.

Man, that is a beautiful coil you have there!!!  The vdc seems about right but you should have a decent amount of amps I would think.  Please don't take offense to this but, have you checked to make sure you have not blown a fuse on the mA part of your meter?  I was reading "0" mA's on several tests before I finally figured out that I had blown one of the 2 fuses on my meter.  Later, I again read "0" and it still took me a while to test the fuse and found out I had blown yet another one.

Maybe try testing a "AA" battery for mA's just to see?  You have a lot of mass there and it is wound very nicely, I would suspect that you should see at least 20-30 mA's wet, possibly a lot more.

I read in another topic that the mA fuses on our meters are very prone to blowing at the slightest provocation.  It might have blown when you first tested it if it was set too low.  Trust me, it does not take much.

I hope this helps.
