could a stainless steel wire be used in replacement of the steel or iron wire

Not a very high iron content. Off hand I would say no.
You can buy uninsulated butt connectors from magnet wire size to service entry size. A bag of 25 of Awg 16 to 12 sizes is about $4.00 us. When crimped right there hard to pull off. 
I wouldn't mind trying the fiberglass. Seeing how the company that is making it for Mw is in the business of just making heater cords they may not want to do it on a larger scale. I think quite a few here would like to try it though. Mw would have to check that out. Im going to wait on that until I see some numbers from Mw.
@ Protonmom: Glad to see we havent lost you!

An observation and question. The magnetic field of the core runs north and south which puts the field perpendicular or 90 deg to the copper and iron windings. What affect would there be if you coiled the "insulated" iron wire around the copper wire then wind that on the core? The iron magnetic field would be going north and south along with the core in this manner. I would think there would be more amps produced this way.
Anyone have any insights or knowledge on this?

I have also been doing a lot of non galvanic tests.  I have had some really encouraging results.

Test 1:

I have wound coils with copper cores and copper wires no iron wire at all.  I have found that it is possible to get voltage and mA simply using copper alone.  You need to use dissimilar diameter copper wires.  This effect works in the ground and out of the ground.

Test 2:

I have also found that a NS coil works using enamel covered copper wire and iron wire in a dry state.  I will admit that I am now very interested in building a Faraday cage to do further tests with this non galvanic NS coil.

laser,

Non-galvonic approach = good for pure research. Is my own approach as well.

Test#1 demonstrates important concept of 'disparity'. It is a NS coil fundamental. (Magnetic disparity) More disparity will be seen with iron and copper but you have clearly demonstrated it can be had with same materials of different size. Again, critical concept in NS coils.

Test#2 further demonstrates that the magnetic field aspect of this coil = fundamental. And perhaps that electrochemistry is not as big of a player as thought.

A few posts back, there was mention of magnetic fields in both copper and iron. The two graphs demonstrated this. A clear disparity. Think hard about this disparity in NS coils and the fact Fe and Cu wires placed right next to each other. In further thinking, I believe the NS coil design is quite flexible as long as certain fundamental relationships/functions maintained. I believe we need to be thinking of field, especially very localized field activity in the windings.

Great stuff laser. I hope others see the value in your experiments. You clearly demonstrated the approach I mentioned in taking a few posts back; fundamental analysis. Every result good/bad is a clue. We just need to test these things forward-backwards-sideways and read the clues. I believe you are on the way. I hope to catch up soon!

Some news about fiberglass covered wire. I explained that others interested in fiberglass insulated copper wire. Their response =
---------------
We would like to avoid having a bunch of small customers that will require the same product.  We would prefer if you wouldn't mind being the distributor for the product and that way you can also keep costs down and we can avoid having to set-up as frequent if we can do larger batches instead of one piece here and there.
---------------
So if there is enough interest here, maybe we can pool resources? Those seriously interested would have to agree on a specification and indicate length they would commit to purchase. Everyone would pay same price/foot and be responsible for their own shipping costs. *note, this not a $ thing for me at all. I would just prefer to order, divide up accordingly, and get my money back*

Should this not be an option, I will try hunting down another manufacturer that everyone can use on their own. In reading laser's last post, I now wonder if this form of wire insulation is even necessary...

That depends on the numbers. If there better or close to it then it would be much cheaper than the cotton. We need the numbers and materiel's from you though. The 1018 in my opinion is the closest to what Ns had and cheap enough. A lower carbon core with silicone may be better but not necessary.
If your numbers are good on the 1018 Im up for 500 feet to start.
You mentioned the iron wire insulated. Are you buying the iron wire and then having them insulate it?

1018 is fine. What gauge? I will quote for 500-1000-2500-5000 lengths (manufacturer's lengths)
Interest in copper as well? What gauge? I aready have quote for 16ga. ($/ft) see below.

500   1000   2500   5000
$0.18   $.161    $.148   $.144

I was not charged for copper in my 250ft sample hence difference with above. They had a small leftover spool they used and only yeilded my 250ft 16 ga sample. Above = standard production quote for everything.

Manufacturer reluctant to do another small run for me in iron, hence I will have to order a larger quantity to get. Iron should be cheaper in my opinion.

Basically I need to know gauges of each. Hopefully anyone interested all agree on what gauge will be. I initially chose 16ga as it is easily formed and suited to smaller coil geometries good for testing.

Its dandy insulation and I'm sure everyone would like using it.

here are a couple of pictures of my fiberglass copper wire as recieved. Material = UN16S-BC, basically a bare 16ga uninsulated wire, soft drawn.

In the background, a rope heater from same manufacturer can be seen mounted on a cooking appliance.

Potential iron wire w/ this fiberglass would look identical. It would be ordered at same gauge as copper thus identical dimensions and clean windings.
