Ok, someone remind me to take a 15 second exposure of my coil
operating so it can look as impressive :-P.  My coil photos are
typically 1 second exposure max.  Id rather capture the spark as it
appears to us in real time, rather than layers of sparks which give a
false sense of being more powerful than it really is.  Richard Hull's
coil is nothing short of amazing, dont get me wrong, but there is no
reason a DRSSTC of the same size could not match that performance, and
possibly exceed its efficiency.

So it means i build my coils with efficiency in mind.  I need to get
the maximum spark length for wall-plug watt that i can.  Most guys
would probably just upgrade to a 50A line and let the coil run at
lower efficiencies.  Spark length vs. input power is a challenge for
me, which i enjoy.

 this is one more reason to say you

20A will kill you as easily as 50A...

 20 a - it is your problem, not mine, coz in our

My limitation is the cost of *me* buying the 8 or 6 awg wire to add my
own, more powerful, line.  The fact is, i dont need more than 20A
because the coils arcs are already the maximum size for my space.  If
i go too much bigger, i risk arcing to power lines.  Anyway, we have a
100A service to our house, so that is in fact the maximum.

 and for symbolic sum of money

My coils will not require power factor correction.  The 6kW AC-DC
converter im designing will pull a very sinusoidal current and
perfectly in phase with the voltage.  Power factor should be .9 or
better im guessing.

Guess how much the 6kW power supply will weigh?  Probably 30lbs max.
Have fun with your 250lb 5kva Pig, plus the 100lb ballast, then the
75lb variac to control it... oh, and the 10kva you will require to
match my 6kW ;-).  It wont take long before people building BIG coils
will realize the large benifits of the DRSSTC: more efficient, more
control, less weight.

Its been fun arguing :-)
