google (to start, there is a lot in these)

electronic goldmine
all electronics

These are some basic places to start and are very good!  Anyone else please feel free to add

Eh? I am not sure what your are talking about?

@all

Mobius !

@gadget

Tell us more about the one you made on a pole .

After reading i know now a bifilar like Tesla makes a stronger magnetic field for the same voltage , now could it be used to boost the jt power , i will need to try ...
...

unless more current flow through it, turns for turns they have the same mag field strenght.

what a Tesla bifilar have is more capacitance.
from a coil turn to turn you may have .1 volt between each turn.
but you will have 50 volts between the first and the 500th.
whitch, in a bifilar coil, happen to be the second turn...

@All:

Great work folks!!!!!

I have been very tied up lately and have only been able to pop in from time to time just to see how far behind I am...and it is pretty far I am afraid.

You all have been doing some really great work here.

Welcome to our group.  As I was reading some of the posts, I was going to try to help you but, I see the others here have beat me to it.  They are a very good group of people.  You will have a lot of fun here and I am glad you joined us.

@ Jeanna:

I do not understand why you keep saying you want to begin an AC topic when everything I am doing is AC. (JT, EB, Fuji, Bedini, etc.)  Feel free to do what you want but unless folks are using diode bridges on their JT's they are all AC anyway.

@ All:

I will try to catch up and comment on some of the great stuff I have missed here in the past few days.  Keep up the great work!! 

We had 3 more tornadoes touch down here within 10 miles of me.  These storms have been rough.

Thank nop , you are fast , but thank god this can be tested easily , i have made a electromagnet from a nail guess what ? one regular and one bi.

I can easily see why this is better ! More current more magnetic current , more capacitance you say well that proved it quite nicely, i want more !
