Greetings, Tesla List-
So...interest is diminishing, is it? Well, I,m sorry to hear it but the
same here, tho the fact that I'm now 90 will have a lot to do with my
own loss of it. Plus...my and my lady-friend's morbid fascination with
our current & lamentable White House soap-opera. I remember the huge
3-phase 440V SG coil on display once, down south of San Francisco.
Secondary wound with cable used in locomotives as I recall. 20 ft or so
screaming, streaming and deafening arcs dancing all around, plus the
accompanying SG. Yea!...Hooray! (Can't remember who made it...)
But my interest was in SRSS coils since that's the technology Tesla
himself would surely have used. His sparks were, of course, just to
entertain prospective investors, since he wanted to broadcast power
rather than make sparks. Cockamamie idea, that, but he didn't know
(altho he may well have come to suspect it).
Either whenever I can get to them from storage or else after, I will
have 2, 12" x 3 & 4 ft undamaged secondary coils (self-resonant at ~100
& 125 KHz), a Landergren 6" x 24", 6061-alloy toroid, and an unfinished
primary assembly to offer up, in the East Bay area of San Francisco.
The primary assy incorporates 4, "pancake"-style coils arrayed radially
in order to create 4 flux paths thru the secondary. Those coils
together with their s.s drivers are made and in place on a 4' x 4'
platform. The rest of the primary apparatus consists of power supplies &
misc. stuff, all intended to establish an overall positive-feedback loop
from secondary-coil current-input to primary coil current-output. I'd
supply prints of the schematics--some as finished, some not so.
And BTW about the List's format: how come there are so many repeats of
messages? Clutters it up way too much IMO.
