Ray's device and video @
https://www.youtube.com/watch?v=4J8uPhKwjG4I'm not an expert, but I think my observations and calculations are correct.
Some observations. (with corrections, typo fixes and changes )
1. We don't know the exact lifting height of the 72 coins.
2. A long run time (maybe 10 minutes ? ) will give a more accurate result.
3. An auto counter installed upon the lifter would give an exact count of the number of
times lifted in 1 hour.
Note...
It looks like only 1/2 (one direction) of the the back and forth motion of the
output is being utilized to do lifting.
If this is correct, then the out put is actually 2 times more than is being shown in
the video ? But then again, using both of these motions will affect the input power
as well.
calculations
1 U. S. quarter dollar coin weighs 5.67 grams
5.67 grams per coin, times 72 coins.
5.67 x 72 = 408.24 grams total lifting per stroke
130 lifts in 103 seconds = 1.262 seconds per lift
(from 5 minutes and 54 seconds to 7 minutes and 37 seconds in the
video = 103 seconds)
lifting height = 3/8 or 0.375 inch ? (approximation from video, could be way off)
should be measured / stated.
0.375 inch = 0.00952 meter
0.00952 x 130 repetitions = 1.2376 meters
... ... ... ... ...
102 grams exerts 1 newton
408.24 grams / 102 grams = 4.00 newtons
... ... ... ... ...
4 newtons x 1.2376 meters = 4.9504 joules in 103 seconds
4.9504 joules / 103 seconds = 0.048 joules per second
or
0.048 watts mechanical out put
and
0.01 amp x 4.2 volts = 0.042 watts electrical input.

IF
Ray's device as presented, is in fact functioning at unity, (that is to say, if my estimation of the
lifting distance of the 172 coins was correct)
and
Ray's electric power in, measurements are accurate.
then
1. Given that the driving electric motor functions at less than unity, his device
is demonstrating cyclic work from magnets.
2. If the pulley which lifts the coins were made to be eccentric, in such a manner as to
match the force change to distance change curve of the magnetic forces...
then also (and by consideration of this factor solely)
the device is exhibiting cyclic work from magnets.
3. When the energy expended to cause acceleration against the inertia of the coin mass
is taken into account,
then also (and by consideration of this factor solely)
his device is demonstrating cyclic work from magnets.
4. Even if my estimation of the height lifted is an over estimation, it remains to be
seen, whether or not the device is O.U. or can be made more efficient.
