so 4 coils around a torroid, where 3 of the coils are 120 degree's out of phase, supposably tuned, "Its called 3 phase no matter the degree's."
The forth coil, Bigger coil, was a current restricting coil, "That was its job."
Simply Put, water likes 3 phase, Why not give the water what it wants? Stan used it! Research EV's and 3 phase please.
Don't forget your series cell, and of course, an calculator. (A Push for 3 phase)
