I wish you all the best with it Honza , I think its looking pretty good !

This could be the shot across the bows for the coal , oil and nuclear industry !

Take care !

I will update you when more info comes in.
In the meantime we need to find way how to do it without the water !!!!!!

It's been done without water. It's called the Bessler Wheel. :-)

Hi Grimer,

Can you post the link so I can see how?

Have you read the posts on Bruces uncle's toy? That involves vortex motion without the water.

I've now realised where the Gravity Pulse Motor's energy is coming from.

Unlike linear momentum, angular momentum has a datum, an "absolute zero".

You can simply illustrate this with a bucket of water.

If you rotate it clockwise about its vertical axis the surface will deform into the shape of a parabola. Likewise if you rotate is counter clockwise. These deformations show that the bucket is rotating significantly with respect to the absolute frame of reference for acceleration.

There is no known datum for linear momentum, no datum, no "absolute zero, no known frame of reference for velocity.

Thus the angular momentum is analogous to temperature and considerations of entropy come into play.

This means that a small mass at a higher velocity is at a higher "temperature" than a large mass at a lower velocity. Hence the colours I have chosen in the above equation. A short period pendulum is obtaining a higher quality of heat from the gravitational field than a long period pendulum.

Now energy can be obtained from temperature differences as the Carnot cycle shows.

The Gravity Pulse Motor is simply demonstrating on a macro engineering scale what the Carnot cycle demonstrates on a micro scale.

One can illustrate the above with a Stirling engine example.

Consider a source of heat with N calories at a higher temperature than ambient and a source of cold with the same number of calories, N, at a lower temperature than ambient.

Let the engine run on this temperature difference between hot and cold untill the temperature difference is exhausted and both the source of heat and the source of cold are at ambient temperature. The system now has 2X calories of heat.

So the amount of heat is conserved. This is analogous to the conservation of angular momentum.

So where did the energy from given out by the Stirling come from?

It came from the difference in temperature. It came from the Ectropy of the system.
It came from the difference in temperature between the cold contribution and ambient, and the difference in temperature between the hot contribution and ambient.

It came from the total difference, the Ectropy difference, being transduced into Stirling engine mechanical energy.

If we like we can think of difference in angular momentum as difference in Momentum Ectropy.

It must be pointed out it is necessary to use a pair of Stirlings suitably coupled to obtain energy from a combined source of heat (calories above ambient temperature) and source of cold (negative heat - calories below ambient). This is clear from the fact that temperature sources below ambient lead to the Stirling rotating in one direction, clockwise say, and temperature sources above ambient lead to the Stirling rotating in the other direction, i.e. counter-clockwise.

This point was brought home to me by the following diagram where you can see that the flywheel is labelled as a rectifying wheel.




Where the temperature source is only one side of ambient (half wave) then single rectification is sufficient - but when it is both sides then full wave rectification is required.

This thread on commutation .....
http://www.besslerwheel.com/forum/viewt ... 139#129139
..... also has a bearing on the use of rectification.

To sum up then, it can be seen that the expression "Heat Engine" is a misnomer since the energy from heat engines doesn't come from calories but from calorie difference, a higher order derivative.

Interestingly enough Newtonian gravity has its part to play in the operation of the Stirling. Like the Rubber Band Motor the Stirling will not work when laid on its side.

Grimer, the above diagram looks like it was labelled by someone who doesn't understand Stirling engines. The label 'counterweight' is actually the power piston. The 'separator/beam' is actually the displacer. There is no pendulum.

Also, a Stirling engine is driven by temperature difference between the hot and cold plate. That can be achieved by heating the hot plate or cooling the cold plate or both, on a single engine.

That statement is not correct. Gravity serves no primary role in the function of a Stirling engine.

Attached below is an animation I created some time ago which describes a novel hot air engine design as a possible solution to Bessler's overbalanced wheel...

You must be talking about a different kind of Stirling engine, Bill.

I can see from Bill's post that I'd better amplify the above.

If the simple form of a Stirling as shown in the previous diagrams is operated with hot coffee above and ice below then the coffee will be trying to turn it one way and the ice in the opposite direction. This is not speculation. It is observation. If you have one of these simple engines as I have you can confirm it for yourself.

Clearly, given a balancing amount of above ambient and below ambient heat the forces trying to rotate the flywheel in opposite directions will balance and the flywheel will remain stationary.

To obtain power from balanced hot and cold sources one therefore needs to couple two simple Stirlings together.

How?

The solution is very simple, fortunately.

If one rotates the Stirling about its vertical axis by 180° then clockwise rotation becomes anti-clockwise rotation. All that is necessary therefore is to couple the hot and cold source Stirlings back to back.

It is interesting to note that this very basic Stirling enables one to understand what's going on more easily than might be the case with a more advanced design.

Are you implying that the Stirling engine as depicted will not run with a heated top plate (hot coffee) and a cooled bottom plate (ice) because both are trying to turn the flywheel in opposite directions? Surely not.

The opposite is true and the engine will run faster due to the greater temperature difference between the top and bottom plate.

I am indeed.

Surely, that conclusion is inescapable. :-)

[ovyyus]

Oh dear, what a mess.

[Grimer]

On second thoughts, I can see what you are getting at.

In my case I am thinking of the difference between ambient and the source, whether hot or cold.

Whereas, in your case there is no ambient.

Mmm. Interesting.

But why then does the cold source run the flywheel in reverse?

[Grimer]

Oh dear, what a mess.

LOL. :-)

If temperature difference is the only criteria then the wheel should rotate in the same direction for a temperature difference of ambient + 10° as for ambient - 10°. It doesn't.

Why not?

[ovyyus]

But why then does the cold source run the flywheel in reverse?

It doesn't. The engine runs in the same direction whether it is powered by the hot side or the cold side, or both at the same time.
