Back on topic.
With our luck, they'll harness this thing and energy will dirt cheap.
But... We'll still have single phase in our homes and thus no "heavy iron"
in the garage :-)

everything that we have ever done is an order of magnitude simpler. So, it
might be _theoretically_ possible, but might require some nonsense like a
500 teraton nuclear bomb.

Back on the three phase issue, many shops use another
3phase induction motor method to create needed three phases.
Some don't even use a starting capacitor. They simple
spin the motor with a pull rope and switch on the current.

I'm definitely not going to try *that* approach with an RP06. :-)

You can break the RP04-II/RP05/RP06 out to run on 220.
The RP04 was a true three phase motor driven item.

My mistake. Maybe I was thinking of RM05s.
So how much power *does* an RP06 require? Both the continuous maximum and
the spinup peak would be desirable to know.

A bitch to change without the field service"RP06 motor removal/replacement
tool" which was a big round six wide pipe to place under the motor so it
didn't drop and crunch your hands flat.

Sounds a bit 3rd world alike .... And the motor is still
not running well!

I have done that before to start induction motors by hand without
start capacitor. Some have dual caps from what I heard for starting
and running. If the motor is hugh sized, capacitors or start switch
circuitry burnted out to go w/ it would be very $$$ and some didn't
chose to have start cap and do the B&S thing start. (pull and flick
switch same thing as choke off after start.)
