I would suspect that you, like me, would be able to BARELY turn it about a 1/3 of a revolution. Simply put: there is a lot of FRICTION. And I've felt the weight of that 450-lb flywheel. I'd hate to have to lift it! Joe tells me that two grown men grabbing the rotary of the 350-pound positive displacement pump --- with all their applied strength --- can barely turn that rotary even one full revolution! And it takes them 2 minutes to do so! I'd say that's a bit of "friction".

Dear Evan,
as I don?t know, if the 7500 pound motor has any iron inside the stator
and the magnets inside the rotor will cogg to this iron,
it could be really hard to turn the rotor if there is no voltage applied
due to this cogging effect ..
Otherwise, if the voltage from the solar panels are applied, I could imagine,
when Newman uses good bearings, that after the powering up phase, when the motor
spins at its idle RPM this 7500 pounds Newman motor only needs about 10 to 20 Watts to overcome
the friction inside the bearing, as there is only mainly the bearing friction to overcome.
As the flywheel is not a fan, this will not drag much down the motor via airfriction.
so airfriction is probably pretty minimal , probably below 10 Watts.
Now let?s say from the 120 Watts of input remains about 100 Watts at the Newman machine output shaft,so
as there is also a gear which amplifies the torque via lower RPM conversion, you have left this 100 Wattsto pump the water 10 foot high.
As we already calculated, it only needs about 17 Watts constantly to do so to pump 0.56 Liters/sec or 5000 gallons
of water per day 10 foot up.
So all in all this pump could waste about 100 Watts - 17 Watts = 83 Watts of power in friction to do the pumping...
As long as we don?t have the exact measurements of friction versus RPM of these devices, it is all
speculation how efficient this Newman motor is.
At least there are smaller pumps that can pump the water much higher at lower input Wattage,
so this was not such a good demo.
