Power measurement - Need your help

[Armagdn03]

Hello,

I have a rather large group of very good natured, curious souls who love the concept of free energy and love to play and learn. We have reached the classic stumbling block! HOW DO WE MEASURE INPUT VS OUTPUT???

I am actually quite well versed in this and could explain in great detail how to do so but I only have so much time in one day and cannot afford more time creating presentations that have already probably been created!

Would the esteemed members of EnergeticForum please point me to some of the best threads they know of / presentations created / documents published on power measurement input vs output?

Thank you all in advance, this will be a useful guide for those hungry to learn.

steady DC power is pretty easy
it is just volts times amps, and multiply time to get watt hours

AC or pulsed DC is harder, you have to multiply volts times amps at ever instant on the wave, then add together all the bits you get for each moment
some oscilloscopes have a math feature that lets you multiply 2 traces to get a 3rd virtual trace that if the first 2 traces are voltage and current, the 3rd would be power, then run the math feature on the 3rd trace and integrate it to get total power.

the alternate way (older method) would be to use an OP amp to multiply your signals and chart your power graph, then cut out the graph from the paper and then weigh the paper to figure out it's area. kind of messy, but it works.

also just converting back to steady DC makes things easier to measure

and no matter how many math errors you make, a self running device will only happen if you are actually getting energy from some external source,
so that is your ultimate proof

Hello,
HOW DO WE MEASURE INPUT VS OUTPUT???

What is your experiment?

If it is a simple matter, it may be that all you need to do is measure the voltage and current in amps on the input side and multiply these numbers together to get input power in watts. Same for the output side.

But if you have AC where the volts and amps are not in step, or if you are using sharp high voltage spikes on either the input or output side, then it is not so simple.

If you are able to show us a circuit, then we could explain more fully.

I can't point to any particular thread because the best method of measuring power output is never used here. Water Calorimetry. It is relatively easy and can be extremely accurate.

I am not sure, but I think the point Armagdn03 is trying bring up "How To measure", and he is insinuating most don't know how.
In his own words he doesn't need explanation, but apparently the rest of us "Hungry Minds" do. Since no one has ever explained this on the forum in a manner that would take a good amount of time to diagram and explain.

I can use a battery to run a set of lights for 3 weeks.
Now take that battery and charge it for a day with an el-chepo solar cell.
Now run the lights for another 3 weeks .
I don't know the power in , and I don't know the power out.
But 3 weeks of run and 1 day of charge seems like a pretty good trade-off.
Free power is impossible , but using everything available is, far from being achieved.
