Gerry -

The secondary voltage is in KV. The equation should read

    Secondary KV = 65 x (inches^0.7)

A 30 inch continuous spark would be 703 KV with Tesla coils. Streamers for
this voltage could be over twice this length. In other words random 5 foot
streamers terminating in air could be about 700 KV. This equation is based
on data from coilers in the past. Present and future data may change it.

Hi John,

Something is puzzling me about this equation.  Lets assume that one has a 30
inch spark.  65*30^.7 = 703 volts ??? or is the equation meant to express
voltage in KV.  Also, is the equation 65 * (inches^.7) or (65*inches)^.7
The latter would yield 201 volts or would that be 201KV
