Measuring electrical power

   Measuring electrical power is very easy in principle and very difficult
in practice.  If the current and voltage going to a device never change
than the power input is simply current times voltage.  Both can be easily
measured with an accuracy of a percent or so.  Unfortunately, while supply
voltages, as from a battery, can be almost constant, currents vary rapidly
with time, particularly when you are driving a motor.  Most current meters
measure the mean value of the current.  This will only tell you the mean
power if the voltage is absolutely steady.

   If the voltage changes when the current changes, which it almost
certainly does, then measuring the mean current gives quite the wrong
value for the power.  What you have to do is to use a wattmeter.  This
multiplies the instantaneous voltage by the instantaneous current to get
the power and then averages the power to arrive at the mean value.
However, even accurate wattmeters can give spurious results if the current
contains very fast spikes.  The current into electric motors often does.

   Things get much more complicated when the power source is alternating
current (AC).  Then, even if the mean current and voltage are absolutely
constant the power can be changing.

   There are two ways of measuring AC voltages and currents.  Cheap meters
assume that the AC voltage is always a pure sine wave.  They turn it into
half cycles all in the same direction and measure the mean value.  Then
they apply a correction factor to convert this into a true voltage.  Since
the AC voltage is rarely a pure sine wave and AC current almost never is,
cheap meters are unreliable even when measuring voltage, much less power.
They only give reliable results if the load you are connected to is a pure
resistor such as an electric heater.

   The alternative is to use an RMS meter.  (Root Mean Square, it's a
description of the averaging method they use.)  This will give a correct
voltage or current reading unless there are spikes in the current.

   There are two standard ways of measuring current.  One is to pass the
current through a small resistor and to measure the voltage.  This is
potentially accurate but is prone to error in practice since the voltage
measured is usually in the millivolt range.  It is easy to pick up
interference or to include more resistance in the circuit than you mean
to.  The alternative is the "clip-on" ammeter.  This can also pick up
interference and may not be better than 5% accurate anyway.  Not all clip-
on meters can measure DC.

I can put 12V AC in a transformer and get 120V AC out.. hehe.. it must be OU!    j/k

Yep.. volts and power (watts) aren't the same.

Doug Konzen has been working on OU devices for quite a while, see http://www.geocities.com/koneheadx/ for some of his prior work.

He's an excellent builder and experimenter. So his video should not be taken so lightly, as I'm sure no one has to explain power measurement to him.

Regards, Larry

Many peoples have been working  much more a while on OU devised - up till today they do not know or not want to understand about correct power measurements.
When all measurements done by right way and correctly, then seems no one "investor"(pigeon) will be found 
Some this kind people even do not look for money - its just like autoerotism - like masturbation.
I can do it! ... Im Messias! ... I can tell you, my son ...
and so one like apostolic blah,
cheers,
