According to Fretwell, two phase power existed 100 years ago, and it
was over two wires, 90 degrees phase difference. Suppose I run it
over 3 wires instead, with a shared neutral, make it 120V. So,
you have a generator supplying 120V, two coils, one shared neutral.
Would there still be two phases there?
(I believe Fretwell said yes)
Your answer?

When you lie you can always make your point.
I never agreed you were right about any of this.
Two phase simply does not work like this
