RSG+Airblast = better performance and less current draw

On my six inch coil last night, I used an analogue clamp meter to 
measure the 11kV pole pigs current draw from the wall. It was drawing 
16A during normal operation and ~30A when the safety gap fired. Total 
spark length was 60" with 0.02uF and ~800 BPS. I placed my airblast gap 
in series with the asynchronous rotary. Spark length rose to over 70" 
and current draw dropped to 8-10A. I think this is because the air 
blast allowed better quenching of the spark and reduced the short 
circuiting of the pole pig. I could now pretty much run this coil from 
a standard 10A socket with no ballast and get over 70" sparks. 
OBVIOUSLY I WOULD NEVER DO THIS but technically it is possible. I think 
alot of the coilers out there could improve their performance if they 
used a static gap with the rotary (I know of many who don't). I don't 
know if this would work with synchronous gaps though. Another advantage 
is that the electrodes of the rotary are less stressed and will last 
longer. Photos soon.
