Okay i guess somebody had a slight error in numbers? Here is what
I got from that short video. After warm up to steady state

INPUT VOLTS = 101
INPUT AMPS = 3.9
RPM = 1400 approx.

Next these are the values I got from his blurry video for output
side coils. First we get the average voltage 72v all the way
up to 86v after 1400 RPM is reached.

This is a static condition of no load or non-loaded condition
therefore no amp reading is possible because current is not
flowing yet.

Next comes the loaded condition where the output readings
come into play verses input.

Input readings do not change upon loading and RPM increases
from 1400 RPM to 1700RPM approx.

INPUT VOLTS = 101
INPUT AMPS = 3.9
RPM = 1700 approx.

OUTPUT VOLTS = 127
OUTPUT AMPS = 3.89
RPM = 1700 approx.

This is where Thane says that the output exceeds the input.
The RPM going from 1400 - 1700 has a calculation also.

So in this case COP is over 1, some might say infinite because
the battery is saying charged while the motor runs and pulls
an EV down the road.

But that of course is not a practical expression in the real world
due to braking and not accounting for the period of time the
that the system has not reached the "CRITICAL MINIMUM"
operating frequency where extra energy can enter.

This is why Thanes say a 50 percent increase in distance is
their company goal.

Have a good day.
