It doesn't matter, moron (only morons capitalize words in the middle
of sentences).  It exists, when you _still_ maintain that it doesn't.
Not only that, you believed that you can't convert from 3-phase to
2-phase with a passive device.  As I said, turn in your degree!

Completely irrelevant.  You can't buy DC from the power company,
either.

Not an assumption at all, asshole.  You were told about it many times
and still said it was impossible.  Turn in your degree now!
