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

[khabe]

Few simple observations:

When Pump is switched  on (uses external power) - water starts to flow, waterwheel and Generator start to spin up but - why we do not see  the Lamp
need to glow at first and then successively lighter and lighter up to normal light
It does not - next point we can see - it just lighting.   OK - let it be 

What is RPM of waterwheel? Then what is RPM of Generator - everyone has own opinion but lets agree it is 1000 RPM (for example).
Do you see adequate fluctuation of RPM when reswitching happend (sleight of hand) - adequate to load what is climbing up 6...16 times at least.

Generator speed 1000 RPM loaded with  Lamp 60W  -
How many wats uses Pump? 300W or 900W
When 300W then after reswitching -> load of Generator is 360W -  we need 6 times more torque to keep the RPM as same (1000 RPM)
When 900W then after tricks with wires  output of Generator need to be 960W - we need 16 times more torque for keeping RPM on the same level (1000 RPM)

Where is Voltage Regulator This regulator must to be able to keep Voltage on the same level when load is 60W->360W or even 60W-960W,
Where is RPM regulator? What kind miracle keeps RPM  on the same level  when needed torque increase 6 or 16 times?

When no voltage regulator - then output Voltage of generator  differs 6 (or 16) times when pump added as load to generator output,
When voltage regulator exists - then needed torque must to change 6 (0r 16) times - what the hell provides this
or RPM must to be change (diminish) 6 (or 16) times when torque of Waterwheel is constant.

At that frequency!
Performance of this Pump is very-very dependenced about frequency - its calculated/designed for 60(50) Hz

PS:
*All those "6....16 times"  are just simplified usage - in reality different losses align with game as well

*When gas-engine driven the same generator then torque and RPM regulated via throttle

I am in no way trying to defend the operation of the Hardy device as real, however some of these effects can be explained e.g. The output of the generator is feeding a small relay that does not pickup until critical velocity is reached. This will keep the generator unloaded until the resonance band is attained.

The resonance band may be adjusted to provide some degree of self regulation e.g as used in ferroresonant transformers, where capacitors tuned with an extra winding provide regulation.

I believe the pump was found to be a T10000. The data sheet is attached.

Note that the current reduces with increased head pressure. This is itself a form of inverse feedback. It is not possible to know what his head pressure is without a current measurement of the pump in action, since I cannot make a good guess from the tubing size and restriction effect of the flow. James Hardy has published no technical data on this or the modifications to his generator.

It is possible that no single part is responsible for OU action, the system must be modeled as a closed resonant loop, with phase leads and lags and resonance band accounted for.

Just a guess, surely lacking information.

In my opinion it is OK to disbelieve and it should not draw insults, better to draw possible explanations.

Kind regards.....V

Yeah, I know well how wound field generator voltage could be regulated - I waited answere from Inventor or from believers 
But even then you can not keep RPM as stabil as seen on the Video - needed torque grows up 16 times when Gen loeaded 16 times higher.
I have special test stand for generators, I have messed with generators years, I do read all parameters included using torque.
You can use what ever wonder regulator - no way to escape from adding traction power when RPM need to be constant.
At that even smallest deflection of voltage - Pump will be detect it instantly - glitch/failure - downtrend voltage, even pulsed ... not correct frequency ...this is not DC playground !!!
OK - AC you can stabilze as well - have you seen 1kw AC stabilizers? I do, but dont see it on the Video. No stabilizers, no compensators.
Audible clink-clang by every turn of big wheel ... belt transmission  was 1 : 4.5 - then generator spins appr 1000 rpm - mostly those need appr. 3600 RPM (when Gas engine) to have 60Hz.
Someone has at least smallest idea what is output  frequency Surely not 60Hz!  Perhaps somewhere hidden AC-AC converter ? Or this "modern" generator was designed for oldtimer-style engine what uses used oil as fuel

It is good to have a knowledgeable person like yourself on the forum. I will defer to your greater knowledge of generators and motors.

By the way I have a large stack of AC stabilizers in the basement, some of which are too heavy for a strong man to lift. I was referring to an inherent stabilization scheme by virtue of "resonant lock" rather than a discrete device embedded in the machine.

Now I will ask a question. Is it possible to have a "resonant lock " with an AC generator if large capacitors are tuned to the driving AC motor, single or three phase. Have you ever experimented with such a thing. I am merely curious as I have seen something like this in a device called the Rotoverter, but I don't know if it is real.

I have played with DC and AC machines as a young man and recently built a  3KW and  10KW gas powered generator from components because I wanted to experiment with the ratios, rather than buy a commercial fixed speed device.

Your experience is appreciated.......V

No, Im not big specialist,
Those generators, I do wrestle with, are very specific - Im in troubles near every day - I dont feel cheap to ask someone for help or to look from books ... included google 
Although those generators are 3-ph DC -  PM generators - trail  3-ph full bridge rectifier and  several switch mode voltage regulators. My mission is to guarantee stabilized DC 12V and numbers of lower voltages when  RPM at 3.000  up to 18.000 RPM ( 6 times ;-) Complicated because very limited weight and dimensions. My best sides are well-sped fighting with losses and innovative design - by general knowledges of electric machines Im very modest guy. So you can understand that for everyday work I dont need to keep fixed frequency. But if will needed in future I will do it via AC-AC converter    Actually one of my wind turbines (I have built several) already uses mentioned converter.
Anyway - of course you can lock you generator to needed frequency - but by my opinion it does not help much - lock/fix  just with  big capacitors - tuned LC -  means that efficent will better for this freq., but it does not lock like literally -  just helps to keep appr. RPM and as simplest is this circuit as much it depends about load as well. I would prefer governor.
The same story is when capacitor  "tuned" motor. Yes, you can have good save of energy when the motor of your drilling machine  is tuned for drilling with small bits, when need to use large tool then you will be in troubles - you need to change tuning every time - it means you have to make measurings/tunings for every next work you planned  Whether why not to use smaller motor - saved as well ;-) actually I just talked about if you meant this video where "tuning laboratory" guys showing their developments, lot of capacitors with switches etg...   LC Tuned motor/generator could be good idea when constant speed and load, for ecample for driving cavity pump/heater ( I have planned to try).
Seems was not much helps from me ...
Hereby Indian guys - look at their hydro power,
Poor Bharats but smart enough to understand about stabilizing and keeping fixed frequency
