Never. Energy is measured by power expended over time. Electrical
power is voltage times current. Voltage transformations occur under
various conditions and can never indicate OU performance without
current or power and time measurements.
Well, that's not exactly true. Set up, say, an Orbo run by a battery.
Capture power from the rotor with a generator and arrange this so
that it charges the battery. If we can eliminate losses in the
circuitry, and if the system is operating at unity, power in would
equal power out. Over unity would produce excess power which could be
used somewhere else.
Now, replace the battery with a capacitor. Charge it first with the
battery, so the initial condition is that pulling the battery has no
*immediate* effect (the voltage doesn't change). If the system is
operating at over unity (after deducting losses), the capacitor
voltage will increase, if under unity, it will decrease.
That's why using supercapacitors in place of the battery for Orbo was
suggested as a test. They were claiming 200% operation, that should
be plenty of power to stay over unity overall. Gee, they didn't do
it! I wonder why not?
The voltage on a capacitor varies directly with the stored power, it
integrates it, so, indeed, that voltage is a measure of power
generation or consumption. It's very simple, whereas power in a
battery is really, really complicated.
