Far out Tk!! You know i got to make one too

Gadget and TK:

Nice work you guys.  I will never be able to keep up with your projects.  So much to try, so little time.

@ all

I a have question.. Why tesla coil doesnt self oscillate? If the tesla coil can create excess energy why it cant power itself without feedback from the secondary?

[gadgetmall]

Because it is cold electricity from the secondary and the primary uses hot electricity.
There is very little current from the secondary . You need Current more so than voltage for a Tesla input . I guess you can try and reduce the Voltage down with a transformer of some sorts to 12 volts and see if that increases your current enough to power up a Tesla supply .

here is a perpetual circuit tested !!supposedly.  it self resonates and powers itself after a tap from a  12 volt battery and is claimed to have been tested by a few . The key here is what transistor and the winds and ratio .and capacitor ..  It is worth Investigating and simple after all we have built many of the similar circuits, .

The battery starter can be replaced by a Piezo Lighter sparker hooked up to a coil for complete independence from a battery .
This circuit can be combined with a modified MEG and to date there has been no one who built or tested and verified it works however the original circuit i posted was confirmed .

Alexander Meissner 1914 - not with transistor at that time
