Hi All, Pardon my late reply.

Interesting ,despite his experience he belongs to old school and don't get/accept quite big toroid status of a modern coiling art.15 years ago he constructed coil with small toroid on it but at 2 kW input it produced 6' sparks. It's been awhile since last time we contacted and I'm not sure what he is up to.

'Equilibrium' between space charge contribution and favorable thermodynamics of arc channel occurs very early in THOR Why's that?Let alone big toroid with decent charge support (But still enough potential),could a DC power be important factor ? Have you tryed a primary polarity reversal during the exps. to observe changes? regards, Boris __________________________________ Do you Yahoo!? Yahoo!
