Well, i never got beyond the model-t Tesla Coil stage, at that age, that and the school (36" high) Van deGraff. But some mention seems caled for of a reliable friend. Who tells the story (he was ca 15 years old) of stripping a power transformer from a discarded XRay machine... 'bout 100KV 60 Hz. Current unknown. He was drawing arcs from one electrode to another when he dropped one. Energizing the ground. So he couldn't turn it off. thanks dave pierson |the facts, as accurately as i can manage, Digital Equipment Corporation |the opinions, my own. 200 Forest St |I am the NRA.
