Limit on coil size

["Tesla list" <tesla@xxxxxxxxxx>]

I attended a most inspiring talk given by Greg Leyh last night in San 
Francisco in which he showed a documentary video detailing the 
construction of his Electrum coil (I sure would like to have a copy 
of that, Greg) followed by a discussion of his plans to construct a 
lightning laboratory in Nevada.  He mentioned that there is a 
physical limit to the size of a Tesla coil beyond which it cannot 
produce an arc due to the frequency being too low to sustain a 
continuous stream of ions.  I believe he said that an ion would 
extinguish before the next one could be generated.  Does anyone have 
an idea how to determine this minimum frequency?
