Stubblefield coils (bifilar) and speculations

Jeanna:

No, thank you for all of your hard work.  As you see, I backed up a little from the NS coil to the electrode approach.  Nothing like lighting a few leds to get some inspiration.  I will get back into the coils later on but for now, I want to test the limits of this set-up.  I have already had comments on youtube that it takes more electricity to make magnesium than I will ever get out of it.  We shall see.

Of my new earth battery set-up running 4 ultrabright 10mm 28,000 MCD leds from my joule thief.  The earth battery is powering the joule thief.  This is so cool.
I know I can light more.

Each led is 10mm, 28,500 MCD, 3.5-4.5 forward voltage and 30 mA's.
