Selfrunning Waterpump-generator device runs 60 Watts lamp...

Hi, Fritz!
I have to disagree with your calcs. Simply, centrifugal water pumps are not OU. They're not "heat pumps", where "surplus" energy (HEAT) is being pumped from an environment.

With the same arguments - I can declare that almost everything in this forums is
nonsense.
BTW: Viktor Schausberger did interesting things with vortex driven turbines -
and thos pump is nothing different.

If you calculated that CoP is 2.5, then from where is this energy comming from?

From hydrodynamics !? Other people working on OU from electrodynamics !?

Pumps like the one we're talking about are quite inneficient devices. Khabe said it's (overall) efficiency is probably below 30%, and I certainly agree with this number.

What efficiency are you talking about ?
If you take as efficiency the work needed  lifting water some meters up - than 30-50%
is the efficiency. If you add the accelerated water flow at the end - the efficiency
is somewhat different.

If the water stream output velocity really is 20 m/s, then the water flow rate is severely reduced. Accordingly, energy calcs results are quite lower, too. Well underunity.

If you take have of the GPH (5000) and have 20m/s - there is still a
COP >1 (what concerns the pump - energy system (excl. generator+turbine)).

Pump manufacturers are "cheating" big with providing ideal/theoretical values for capacities. But flow rate is easily measurable - there are good and not expensive flow meters on the market, still the easiest way is filling a known volume container in known time....

I agree with that.

I have a "state of the art" centrifugal pump (all stainless steel and 2" output to pipe, single phase 600W). It's nominal capacity is declared at 14000 l/h, but It never went above 11000l/h (and that was at the beggining of emptying the pool - height difference less than a foot.). When the pool is allmost empty (-2m), it's pumping capacity is reduced below 5000l/h. So a  140m3 of water is pumped out after cca. 26 hours... Ah, yes, output pipe ID 2"/5cm, lenght 4m. If I would put a 1" "nozzle" at the exit, it would probably take a week to empty the pool.

I own a similar pump (...)

The pump is definitelly not the source of OU in this setup. So - turbine or generator?
As turbine - "paddle" wheel (the spoons on a pulley every now and then) is (sorry to say) - rather primitive - highly inneficient. No OU here either.

Where do you got your truth - "owning a pump" !?
A pump like this is from the mathematical point of view at least as complex as the
other parts involved.
It feels like you own a wide range overunity detector.

If this setup is really self sustaining, than the generator must be at least 10xOU.

Why ? because of the rotten copper inside !?

Why sould OU only occur in generators ? Thats bizarre.

Either that, or "inventor" lies.

There is no truth and there are no lies - only different perceptions
of reality.
The problems we are facing today are based on the illusion that there
is a truth somewhere out there - and if you are not willing to believe
that - they judge you in the name of the lord.
I dont like that.

What is more probable?

I dont know.

Cheers!

Prosit !

OK All,

We all agree that the math proves it can't work.  The pump is all wrong, the generator is all wrong, the water wheel is all wrong, nothing makes sense................................

I dont agree.
If you find a way to accelerate a water beam without adding excessive
pressure/load to the pump - then you gain a surplus of kinetic energy.

 I am betting that the setup would not have ran by itself for very long. The amount of energy used to start the process would have lit that bulb for along time and I am betting it would have lit that bulb longer then what the setup does.

I tried to figure out what back pressure the
1 inch hose causes to find a realistic operating point for
this pump.
Normally, the Bernoulli equation keeps everything below
overunity here (...)
Maybe someone here is more used to this calculations.
Whats clear from my calculations is that the kinetic
energy "takes off" > 15m/s.(velocity goes in with power of 2)
The kinetic energy with the recommended 4inch hose is
pretty nothing -> only 1,3 m/s. Otherwise, the length of the
1 inch hose is short.
So everythings still unclear.

BTW:

Watching the video again near the end where the paddle-wheel is spun disconnected, there is an obvious "kerchunka" on each revolution, once per turn.  Either due to a bent shaft, an out of balance wheel, something loose, you can clearly pick it up. 
Rewinding back to the zoom-in of the paddles, where the device is running closed loop, you can clearly pick out the kerchunka sound.  Watching the seconds count and counting the sounds, there are, on average, very close to 4+ per second.  That would put the small pulley somewhere around 18-20 per second, and thus the generator, if the 4" pulley is on its shaft, would be turning 1100-1200 RPM.
