Hi Mike and all

It seewms that the acceleration of the main wheel occures between 11 and 2 or 3 o'clock.
Probably due to a Milkovic pendulum effect. Than the unbalanced wheel helps to finish the revolution.
If i am right this wheel seems to be more a dynamic (centrifugal force ) than a gravity machine.

What do you think?

Laurent

I think we are beginning to close in on what is happening here. It appears that there are 2 separate forces being applied to the main wheel: An impulse force when the weight is flung out and reaches the end of its tether which is then transferred back to the connection point on the main arm and the more obvious, overbalanced mass appying tortional force to the main shaft. I think the impulse force is a type of 'freebie' in that is simply a by-product of the overall rotation. It is also clear that the relationship of speed and mass can affect the efficiency of the device.

Hi All

At the 12 o'clock there is the change of direction, before 12 the weight is moving upwards, after 12 the weight is moving downwards but the far end of the weight still has momentum and so pivots to the right and upwards. The amount it moves depends on the RPM of the main wheel and the same happens in a sling shot "point of release would be the 12 o'clock point". This is the effect that you see.

I have worked out that instead of using a wheel to push out the weight at around 1.5, a "free running" wheel could be used at around 7 o'clock to push the weight inwards to 90 degrees with the main wheel, the one way bearing would hold it there, also less drive loss because it would not be driven, the weight would run over the wheel "still a loss but less than a driven wheel". RPM can now be increased to gain NEAR full extention of the weight before 3 o'clock.

Point of power gain

Thinking allowed again, the power gain in this design as a generator is the voltage always stays the same, what changes is the current

USED INPUT on start up and running under load 250v @ 4amps = 1kw

GENERATED OUTPUT 250v @ 12amps = 3kw

NO LOAD INPUT possibly only 0.5amps @ 250v = 125watts so will self run !!! maybe if things are isolated

Hmmmm. Where have I heard that before???

"Somewhere in this thread is the suggestion to do just that. At some slight frictional loss but clearly more increase in torque, you could add a second small wheel at around 7:00 or so. This wheel wouldn't even need to be powered but simply act as a passive rolling interference to push the weights in toward the center of the large wheel. Once pushed in, the one-way bearings would hold them in and increase the overall over-balance of the larger wheel."

Glad we agree!

Had not read that post of yours, I calculate first, and yes we do agree, but it also gives the possibility to increase RPM withoutcausing adverse problems and no need for the other wheel @ around 1.5 using energy.

Regster,

I would be interested. I have started a replication and instead of one-way bearings I am using a mechanical "sprag" type stop to prevent counter-rotation. My rotor is only 4' in diameter so I was unable to fit the 32 weight sets that Mikhail has and mine only has 24. So if your program is flexible enough, this may help me immensely to determine how this will react.
Thanks in advance. Please send me a PM or email @ purelyprimitives@charter.net

Regarding the 24 weights:

The key to overunity. Attention! Aсhtung! ¡Atención! 警告 It is very important! - YouTube

Of course it could be inaccurate.


Excellent videos Woopy!

Still no word from Mikhail yet.

Great work so far guys!

Loving the freewheel improvement.

I'm sure there are many more improvements to come.

[purelyprimitives]

The "attention" video is over 2 years old but he did use 32 weight sets
in his latest design. I'm hoping that the 32 weight set rule
can be bent especially now that we are learning more about
how works. The latest video from Mikhail without the bicycle
wheel along with the "simpler and more efficient" prototype 12
on the near horizon hopefully means that there is roon for
variability in the design.

Mike

I think I wrote that prior to seeing Mikhail's last video as well
as the ones Woopy has shown. I'm now convinced like you
that the driven bicycle wheel isn't required. Hopefully Mikhail
is way ahead of us and this is what we will see in prototype 12.

hi!

Last year I've built small wheel with 2 (4) pendulums with one-way bearings and with magnets...

Free Energy Gravity Wheel - the basic principle - part 1 - YouTube

I have no more experimets yet...

btw: I have a back up of the photos from Dmitriev's site -

good luck Woopy with your replication!

Hi all

Today i tested a lot of different config with longer and shorter fulcrum, and different weight and speed , with and without the one way bearing,

So my first result

the one way bearing seems to be mandatory.

Because the free swinging fulcrum are not only unmanageable but often they are working in counter rotation and invert the process,
So sometimes they increase very strongly the effect and sometimes they opposed the movement,
So i will suggest to go on only with oneway bearing (not so cheap but probably unevitable ) Which confirm the Mikhail work,

So Mikhail is using a Motor /generator, in the same unit, i have seen that such unit exist such as (ROESEL motor /generator ) which seems to choose between the motorising moment and the generator moment all in one.

Perhaps Mikhail is using such a system.

So that give me the idea to connect a generator (shorted to be at max electrical demand ) and try to feel with my finger (acting as prime mover ) if i can feel something.

And i am totally conscient that this test is totally subjectiv, but i feel a really big difference.

So at the low speed revolution, when the fulcrum (weight ) are simply hanging , i have to apply my hand torque strongly all around the 360 degrees

as i speed up the wheel to the critical value, the torque seems suddenly to be much more free and seems to be applicable only at the sector between 4 and 6 0'clock .

So to say (of course subjectiv ) , it seems that

first i am increasing the rotating speed of the shorted generator, and by doing this ,my hand power is notably decreasing

OK just a pure malt whisky and a good sleep is necessary

hope i will not be fooled tomorrow

so be very carefull with the annexed video

good luck at all

Great video Laurent.
So, the required force when spinning faster only seems to manifest at the 8pm and 2am positions ? which would be the same as those noted for the swing out and swing in points ?
Do I have that correct ?

The fact that the resistance of the shorted motor was lessened with increased speed and weights flying outward, is intriguing.

I hope for a video from you and for you where you say "and now we let it slow to a stop without the power input, oh, it isn't stopping" !

Great video Laurent.

See reply #96

[Michael John Nunnerley]

Hi Laurent, interesting video, seems there are some very strange things happening, almost as though it is a complete reverse to what you would think! I still think that the only real way to see what is happening is to plot the current draw on that motor, as a motor, and in relation to the degrees of turn of the main wheel.

I would do this myself but at the moment I do not have the equipment here to build it or the time.

Keep up the very very good work you do

Mike

[Regster]

I have to admit to feeling a little frustrated here.

By far the most efficient way forward here is to get this device physically modelled in Autodesk Inventor ASAP. I mention Inventor because it is free to download for personal use so everyone on the planet could get to play around with the model once it's complete. It would also be far quicker to tweak the design to reach a point of optimum efficiency in virtual form.

If I had the spare cash to fund all of it I'd have done it myself, but I don't so all I can do is contribute to a fund if one is set up. I know Paul mentioned getting something put together in Solidworks as being part of the general donations (I have donated btw), but I really think this should be an overriding priority in terms of moving this forward. Not in Solidworks, but in Inventor - for aforementioned reasons.

So proposed plan:

- Find eco-focussed designer with extensive Inventor dynamic design experience and get price based on exisiting photos (or anything else Paul has).

- Raise the cash and pay the guy/gal.

Bish bash bosh... do this and maybe as soon as next weekend we could all have irrefutable and distributable evidence that Mikhail's invention works and we could have optimum X, Y and Zs shortly after for the physical replicators.

[soundiceuk]

Sounds like a great idea Michael.

The modern way to carry out compression tests on petrol and diesel engines is by disabling the fuel pump and using an amps clamp on the battery cable to measure starter motor draw on cranking.

Certainly easier than removing 12 spark plugs on a 12 cylinder engine.

The scope shots will show a low compression on a certain cyclinder.

I believe your idea will function the the same way.
