No, no jesting.  Our model M-150 system uses these exact parameters and it
produces 1 MEV with 9.5 ft. long discharges.  Coil length is 52 inches.

John Freau used less than 900 watts in a setup with a very large dia coil to
produce incredible output sparks over 42 in long.

Large diameters promote better coupling of energy from pri to sec inductors.
