I will need more information on the paddle wheel and what size of tips he was using?
I know the 1:4.5 ratio from pulley to generator was 18" and 4".
I also know at 25'/*.434 =10.85psi will create a thrust of (1.57*psi *d*d) or if it was 1" tip the total thrust will be (1.57*10.85psi *1"*1")=17.03 lb of thrust. Basis on water rocket thrust formula, it's the right formula!
(18"/12)/2=.75' constant pulley load or 17.03*.75=12.78ft/lb
The total FPS of thrust is SQR(32+32*(10.85psi/0.434))=40fps
My question is how big was the paddle wheel?
If it was 18" then pi*18=56.55 or 4.71ft
This means total rpm without any load would be (40*60)/4.7=510.64rpm's and with the 1:4.5 ratio the generator speed is 510.64*4.5=2297.87 rpm's.
But the torque is now down to 12.85/4.5=2.85lb generator pulley load.
Even with max output at 100% you get (2297.87*2.85ft/lb)/5252=1.24hp or 930.2 watts of power.
Input is needed ASP.

That pulse water wheel is a legitimate device.
If you make it right you will succeed.
Hi Armcortex,
I do question this build, but it should be fun also.
I will try to keep it simple, I must first try to get the max flow and pressure from the pump verse watts needed.
And then it's plain and simple with a basic water wheel design I can calculate rpm's torque and output on generator head...

I think that the key to this "water wheel invention" is the battery denoted with the number 6 in the drawing of the patent depicted here http://www.overunity.com/5176/selfrunning-waterpump-generator-device-runs-60-watts-lamp/msg113275/#msg113275 (http://www.overunity.com/5176/selfrunning-waterpump-generator-device-runs-60-watts-lamp/msg113275/#msg113275) . (The patent is also attached.)
The battery (if charged) will drive the contraption for some time. A 30 second run would not be a surprise.
Even if the switch (5) is off, the transformer (2) and the battery charger (4) might connect the battery to the pump. It is not clearly specified in the patent how the transformer (2) and the battery charger (4) are wired internally. In the patent it says that the transformer puts out DC current, which suggests that it is more than a simple "transformer" and the "battery charger (4)" could be anything (e.g. a simple full bridge rectifier).
In any replication this "battery problem" has to be clearly resolved. I am sure you are aware of this important detail.
The water wheel in the video looks like being very inefficient in relation to the amount of water being pumped. And please be careful with water near a 110V or 220V genarator, it can kill.
Greetings, Conrad
Hi Conradelektro,
I that you for your input.
I also understand being shock by 120v ac, but really depends on the eletrolite in the water that increase watts.
I was thinking in those terms also using a alternator first and a inverter to drive the pump. But before any output, I must find the max load of the thrust and fps to get a better idea of what it can power.
Thanks.

The danger of operating a submerged pump, on utility current caused me to think...Suppose the pump motor was designed to operate on
a landscape voltage of 32 volts instead. But instead the guy overloaded the pump motor by operating it on rectified 120Vdc or even
120Vac. This overload could cause PM permanent magnets in the motor to be erased, showing overunity while doing so.
The standard water utility pressure is 80psi, in the video it looks like water curve is being driven above 80psi, suggesting again overload
driving of the pump. The flowing water would supply cooling to the pump, so overloading wouldn't immediately destroy it.
The other claim was the generator was modified. Those unmarked white capacitors look suspicious to me. They are supposed to
be in the excitation field. Maybe they are batteries, causing temporary overunity.
Do be careful, that guy was wearing rubber gloves I believe. Chlorinated city water is plenty low enough in resistance.
Two things: you can build a 1:1 line isolation transformer out of two hefty line transformers hooked up back-to-back which gets rid of
ground conductance problems. Two, consider having a helper who can stop the line current should anything untoward happen.

Hi Mark,
I understand the city water electrolite up here in N. Pa I have good well water.
That does not mean I want to bath in the electricity.
I'm setting up a simple test as I write.
Tom...
First pump test using 1.5 ID output, could not get watts due to 30gal running out in seconds..

Hello All,
The problem with the James Hardy water wheel is power to the water wheel and flow.
I will have to get a bigger flywheel with paddles and see if I can get enough torque to do work.
I like to add my water project to this experiment also.
This is a water design I call the Submersible Displacement Engine using waves to generate compress air that gets feed down to the displacement tubes.
As air is trap, it cause the displacement to rise to the surface.
This is a simple test using this design as a efficient water wheel.
