@bill

there are 4000 turns of 28g wire on the secondary.

This is one of the reasons i believe that you here the description of the cell being plant pot sized, the primary may just be 5 layers or so but its the sheer amount of secondary windings that give it its bulky description.

@jeanna

as ive built my cell in paralell i believe this is why i am having to short the bottom iron wire on the cell with the top copper wire on the cell to see the best results.

Im in the process of obtaining more bare copper wire, il leave the first cell in the ground and take periodic readings and get to work on a simple make and break in my spare time.

Il get to work on a cell thats described in the patent, i have about 9lbs of 28g copper wire for the secondary so il put all this on and see what we get.

I didnt have the funds at the time to buy material to make a cell like the one in the patent so i had to improvise a little.

Cool Note,
  I left my copper rod in the ground all winter its a good 5or 6 feet long and its had the weirdest effect. It seems the snow has melted arounnd it in a bout a 5 foot diameter circle,  i mean thres a foot or so less snow there compared to the rest of the lawn, wierd right?

@ Joe:

I have observed the same thing with my electrodes out in the garden.  When it snowed, there was about an 8" dia. circle around the positive electrodes where the snow was melted away.  This means there is heat, and to produce heat means....yes...ENERGY!  Remember my story about me putting a load on the cells and earthworms flying out of the ground?  A lot going on under the ground out there.  Still no word from Hans, I really hope he is ok.

@ One:

Sorry, I guess I did not understand your post a while back.  I thought you said you were pulsing the primary to see what you would get on the secondary.  My error.  I am just very interested in what will happen when we all wrap secondaries and begin the pulse attempts.

@ Chad:

Thanks.  I remember it seemed like a large number to me when I first read it. 4,000 turns is still a large number.  I was going to attempt to calculate the length of the wire (magnet) needed but it is not so easy to do.  We have a starting outside diameter of X which using pi we can figure how much wire is used per turn but, X increases with each layer and then requires more and more wire to do each turn.  I guess we could figure in the diameter of the magnet wire and see how much larger the coil dia. is getting per layer but, that would assume perfect  layering and winding with no overlap.  If anyone has a good idea how to figure this, I am all ears. (I think Spock said that once)  I would hate to think I had enough wire only to run out halfway through.

Hi Bill,

I think this is what calculus does well. I don't remember how to work a dif. or int equation, so that's not happening here. But this ought to work:

Use 3 or 4 diameters (lets say 4) and work out what the circumference of one circle in that diameter is. This is the length of wire needed to go around that one wind. then multiply that length by the number of winds possible in an inch of that

then multiply times the length/inches of the coil.

Do this for each layer then add them all up.

If you then divide by 4 you will have a kind of average length of wire for each layer.

Multiply this average by the number of layers.

Add another half length and you ought to be close enough to buy the right quantity.

I hear folks talking about pounds of wire not length so you (we  ) may need to calculate the weight somewhere along the way too.

If this doesn't make enough sense, I will try again, so please tell me if you want to hear another version.

PS. Joe and Bill,
That is really cool about the copper melting the snow. (Maybe that is the real reason copper used to be used in roof flashing, to keep the ice at a minimum.)

@jenna

You could also measure the length of your wire,  take a set ammt record that length gauge ect. Use the coil calc to get the MH inductance and then make a proportion for a larger wire size

set length                                   x
--------------   =       -----------------------------------------------------
set inductance        desired inductance for desired freq
