@CaptHook

Let him be right.  And he will be right.  Right up until he throws the power switch and puts 20KV across a bizillion turns of number 44, and melts the wire leading into the coil.  But I think the really, really fun part will be winding a bizillion turns of #44.  Better make a good jig to do that.  I have a hard time with #30.  My current coil that I am playing with only has 3920 turns of #26, and it took me two weeks to build.  Of course it is very large and made from iron pipe.  But you know we were all there once, and someday EvilXBOX will look back and say Doh!

z.monkey - ROFL  :D

- - -

What about your core?  What are you going to use?  What is its saturation point?

Have you ever wound a coil?  Do you know how long it would take you to PROPERLY wind an 8 mile long coil?  100 hours would be a low guess..... IF you could even get a whole coil wound without breaking it (doubtful)

The point is - you can obtain a comparably powerful coil with low power draw using common volts/amps with a manageable wire/coil size.

Start off small - - -

8 miles of #44 x 4?  FORGET IT DUDE - REALLY!!!!!!

CH

BTW: if you calculate the AT from the data you provided:

2000V / 10372000R = 1.928e-4 amps

1.928e-4Ax 40,000 turns = 7.713 Amp-Turns

All of the simple coil examples I gave you BLOW that out of the water and consume about the same amount of power.....( yours .39 watts / 7.7 AT  - mine .44 watts 206 AT)

So for 10% more power I'll get 2900% more Amp-Turns.    ;D

Anyone wanting to spec coil design should check out this handy on-line Inductor Simulator:

@capthook

Thanks for the link. I had been looking for something like this program on and off for sometime now.

Here is the ideal coil spec I have derived for my project and will be winding tommorrow:

#26 AWG / 250? / 10 ohm / 1250T

1.23V x .24A  =  .295W (how did I derive this?  Attached my power supply (1 "AA" battery) to a variable resistor set to 10 ohm and tested with DMM)

.24A x 1250T = 300 AT

So 300 AT @ .295W consumption - pretty sweet IMO.......

Why can't I find any information on Amp Turns?
Give me a wiki link, or similar
thanks

oh no, my calculator died going to the reply page...oh well, computer only now..until I get 4 AAA....

this is what capthook posted, to my one pound that I have already calculated
2,000V, 2ft circumference
44 AWG / 80,000' / 207440 ohm / 40,000T
2,000V * 0.00964134207482 Amps = 19.2826841496336 W
0.00964134207482 Amps * 40,000T = 385.653682992673 AT

385.653682992673 AT @ 19.2826841496336 W consumption @2,000V
...tell me what to compare it with?

to one pound of 26 AWG...
24378.3520234032AT @ 78010.7264748903 W

tell me what else to compute?

the ratio of my AT/W is 20 for 44AWG(on the dot) and 0.3125 for 26AWG

Updated spreadsheet so you can play with values

http://en.wikipedia.org/wiki/Magnetomotive_force is what I was about to paste in here, as someone in EFNet just linked me(I found it before, but this time I bookmarked it)
Does anyone know of an OverUnity chatroom on IRC??
I think I will get that spool today, on the 7th
..a little more than half a pound for each rotor doesn't sound bad or anything, I just wonder how powerful it will be with my other techniques I am using

Your coil:  386 AT / 19.28 W = 20 AT per watt

The coil I am winding: 300 AT / .295 W = 1017 AT per watt

And the coil is small, cheap, easy to wind and uses common/small volts/amps.

You seem like a bright guy - you have a basic grasp of some of the fundamentials. However,  you certainly can choose to ignore the good ideas presented to you and do it your way - but I would discourage it.

that was for 1.5v, not 2,000...use my spreadsheet to determine things, I havent sat down to figure out the exact differences though
