Overunity (what is it?)

[TechStuf]

Tinman, think of the bubbles as a lot of "ball bearings" alleviating water's elastic death grip on the rotor.  Griggs's setup has been tested by various universities, and found to produce more heat than is taken in as electricity, and the technology has not reached it's full potential by a long shot.

Tinman:

I can only offer you a theory for your story.  I believe that I have good to very good mechanical aptitude so I will give it a try.

For starters, the drum setup is not a water pump so you can't compare the two.  Here is the theory:  The pump was obviously being stressed to the limit because the water started to cavitate.  When this happens, all of a sudden the water pump is not pumping water anymore.  If it's not pumping water then the mechanical load on the electric motor goes way down and thus you see the current consumption drop.  It may seem counter-intuitive, but that's the likely scenario.

Now, just for fun, let's take a step back and just look at what's happening at face value without knowing the specifics.  The old Black Box experiment.  If the current consumption of the motor drops, that means the load on the motor has dropped.  It's as simple as that, nothing to think about.  Now put that together with your example and you can say with quite a bit of confidence that when the cavitation was happening there was a reduced load on the motor.  It's the same idea with the drum.  If you are told that the drum is producing more hot water thermal power, then without even looking at it you can look at two possibilities:  1) the driving motor RPM increased, 2) the torque supplied by the driving motor increased.  If you are told that the cavitation in the drum increases the thermal power output then with your eyes closed you can say that it takes more torque to drive the drum when cavitation is happening.  In this case the cavitation increases the friction that wants to stop the drum from turning.

Going back to your story, if the pump has stopped pumping because of the cavitation, the the the water flow at the output side of the motor slows down.  It may slow down a lot in a fraction of a second.

Then the cavitation disappears and all of a sudden the motor is ready to pump again.  However, there is a problem.  The problem is that you have to overcome the inertia of all of the water in the pipe again because it has slowed down a lot and the pump wants to resume pumping at the normal flow rate.  In fact, that's the mechanical inductance of the long pipe filled with water that's causing this problem.  Mechanical inertia is a form of inductance.  So the pump now has a double load, overcoming the inertia of the water in the pipe, and the regular load that's always there.  The motor/pump can't drive the double-load and it chokes and slows down a lot.  Because the motor has slowed down a lot, it's not generating enough CEMF, the current shoots up, and the breaker trips.

in my youth,and racing formula 3 tunnel boat's,once you trimed up to high,the prop would cavitate,and RPM would go sky high.

That is a somewhat similar example.  When the water cavitates the blades of the prop are not pushing on the water anymore to drive the boat forward.  There is no more load.  The blades are driving "empty space" or "room temperature steam" instead, hence the propeller RPM shoots way up because there is no longer a load to drive.

Please show us some data.  Otherwise it's just talk.

You should listen to Tinman's words of wisdom.  I already told you in a previous posting that my alias just popped into my head, it's not a drug reference at all.  Don't even think about making follow-up comments along that line.

Gulp;  I'm sorry, it won't happen again.  And my sincere apologies to your dealer.  I do not wish to offend the cartel!   
 
It was an honest question, wrapped in a joke, inside an enigma.  I truly wondered if you selected MileHigh for reasons of lifestyle rather than location.   Feel free to write an unauthorized biography about my username if you wish, I can take it.  My skin isn't quite as thin as some.  I might even get a chuckle and encourage further hyperbole!  Instead of offering up the over reactionary, "don't even dare" line of defense of what is in fact, just a thin, arbitrary veneer.  As you said, an "alias".

Us?  Do you have a mouse in your pocket, or is Harry Dunn over for a visit?

If you cannot see the evidence already shared for what it is, then your optometrist has my sympathies.

Better days, seeing through the haze, and navigating your maze.

If you cannot see the evidence for what it is, then I am sorry for you.

Really?  I view the above comment as pure spin and disconnected from reality.  You simply don't have any evidence that I am aware of.  The original fire station clip is more than 10 years old now and the guys have wised up.  They don't make claims of over unity.

Just by saying "there is evidence" does not not cut it for me and I am sure that there are many that share my opinion.  I won't let my brain get comfortably numb and just believe what you are saying just because you are saying it.  You see that often in the realm of free energy.  Just look at Sterling Allen's web site.  Very recently there was a comical motor-generator clip from some Romanian guy where you can see where he tried to hide the power cord for the second motor underneath a 2x4 that formed a stand for the contraption.  The vast majority of the comments say that the clip is pure junk yet there are still posters that just blindly want to believe.

I won't ask any more and if you don't provide evidence the readers of the thread can draw their own conclusions.

Webby1:

Like I said, you can't compare apples and oranges.  One is a friction heater and the other is a pump.  They are completely different things.  The cavitation in the friction heater does not affect the integrity of the thin water "skin" that is wrapped around the inner drum.  What it does do is create a "disturbance" to the quasi-laminar flow of water that would exist if there was no cavitation.  That disturbance to the quasi-laminar flow causes more resistance to the rotation of the inner drum.

For a pump, some kind of cylinder is sucking on a long cylindrical plug of water and pulling it through a long pipe and there is resistance to the water flow.  When the length of a pipe is over 100 times the inner diameter of the pipe it acts just like a resistor.  When the water cavitates, then the pump is not pulling the water through the long pipe any more hence the resistance experienced by the motor goes down.

Going back to the drum heater, if it was driven to the point that the thin water "skin" that surrounds the drum itself cavitated, then the resistance to rotation would drop sharply and the drum would speed up like crazy.  Does that make sense to you?

Would you like to be called a crack hoe?

I'll tell you what.  Think instead about having ssex with a 1974 Sylvie Kristel in bathroom of an airplane during a long transatlantic flight.
