Hi Reinhard, Terry,

Methinks you are on the right track with relating the ozone production to the 
size of the discharge. John Freau reports that he gets considerable ozone 
from his VTTC throwing 19 inch sparks. Not only is the 3O2 + energy yields 
2O3 reaction unstable, less than
8% of the available oxygen is utilized before the reaction reverses. The 
triatomic
molecule uses 8 % of 20% of the volume of air in the room. So the way I seez
it, my little VTTC produces no detectable ozone because the volume of air 
within the discharge "sphere" is too small.

Maybe there is some ozone but ony our Weimaraner can smell it. ;-))  

Happy day,
Ralph Zekelman
