The interesting thing on the WOD clips that no one has ever mentioned is how the acrobat is actually performing commutation on the wheel.

As he jumps from one rung to another, he simultaneously destroys a torque field as his weight is removed suddenly then suddenly applies it at another point, instantly creating a new torque field, shifting CoG of the system, causing the wheel to react in an new direction.

This shows that another missing element is necessary for a PM device and that is counterbalancing. With counterbalancing, we can shift the CoG with no loss of PE. As the acrobat maneuvers on the wheel, he is applying energy creating a reaction force against the high inertia of the wheel to gain back lost PE. With counterbalancing, no PE is lost - "one weight is giving an upward impetus and another is giving an equal downward one" from the man himself (JB).

...a binary solution (yours) and the " unbalanced pair (also yours) do work well together. thank you for your patience.

...a pulse generator with feed back.

The pair, gives us a generator / commutator arrangement, both of which rotate "parallel" to each other and supplying an pulse of energy from The (Generator) weighted wheel...to the commutator.

it is, as you say...the binary beat.

As both the generator and commutator are unbalanced to each other AND in balance on a common axis of rotation...the beat goes on.

...

...it is not necessary that the wheel(s) share common diameter, only that we can generate a pulse from one..into the other...

this is PM...Yes?.

...This is what I believe Bessler to mean by One side heavy, the other light and empty.

a light wheel fixed firmly to an axle with several holes at equal distance and radius...

..a heavy wheel with pulleys rides on there axis in individual vortices around the holes of the light wheel

.....implies firstly,the gravity-inertia paired phenomena.

We need action,so to move things,to do some works.

Any action needs acceleration.

The gravity field we are living inside ,is a natural accelerator:is can fast the motion of bodies,or the impetus gained by this movement(m*v).

Really,we are interested about the quantity of motion (momentum),of a moving body,as a product of its mass and its velocity.

We can take out "fresh" motion from gravity (fall) and amass it as rotational inertia (the best "storage").

This is: gravity action=inertia reaction.

A heavy pulley and a falling mass on a string is the image of this motion tranference from gravity to inertia.

OK Jacob with our binary wheel created by commutating the weights and resulting stress isolation between short arm lift and long arm descent systems we achieve our desired continuous unbalanced pair configuration.

The weights ride the wheel rim for the descent producing maximum torque at the hub then are physically transferred to the lift system. The lift system requires the same PE to be input to lift the weights but due to the short arm produce only half the negative torque at the hub.

So vertical PE must be paid back but because of the short arm lift system, only half of the rotational PE need be paid back as only half the descent torque at the hub is available on the lift cycle. Since the systems are completely stress isolated, neither side knows or cares what the other side is doing. There is no longer any mechanism or stress path available to balance the system.

There is no longer a built in "tracking system" to total how much work was done on the descent path vs the lift path. This information is now lost to the system. The tracking system consists of stress deformation in the physical structure side to side which we have now eliminated.

Eliminating the negative torque weight for the lift cycle (or half of it) is equivalent to eliminating back emf in an electromechanical system.

The system is just trying to equalize torque values side to side but the only option the system now has to equalize torque values is to rotate.

The system must see a gradient torque field in which it will try and reach the bottom of but at the bottom of the field we instantly commutate the weights to continue the process.

Does this sort of mechanism occur anywhere in nature? Absolutely - at the nuclear level almost all reactions occur by a process of continuous exchange of mass particles back and forth between otherwise isolated systems.

Hi Camper!

.....regarding the natural continuous motion (let's say this obsessively latin representative epithet "perpetuum mobile") you can meet at binary stars.

It's a rotating cosmic seesaw...a system of two stars that revolve around their common center of gravity.

Can we "copy" this natura model? Hard to say,for the moment...the fulcrum is unseen and "located in the empty space..."

An appropriate binary system is Earth-Moon:we can copy it ,so easy!

It's an another self-rotating cosmic "see-saw"...

By the way: the binary solution is on the line with Archimedes ("give me a long enough lever and a place to stand...").

Good news Jacob - we have a fully commutated and stress isolated binary WM2D simulation operational. Eight weights, each weight switched four times per wheel rev, with eight latches. Self starting, accelerates to 45 deg/sec after 90 deg of wheel revolution. System resets four times per wheel rev. The sim is still blowing up at the reset point as I don't have the latch formulas perfect yet. 64 commutation and latching events per rev!

There are 16 formulas to be entered (if statements) that have to trigger the commutator/latches precisely. The physical rep is half done as most of it was salvaged from the last build. Commutation is the key - it's back to the future baby!

[iacob alex]

Hi Cloud !

As you said: "...commutation is the key..."

Really...

We need two commutations (long arm into a short arm and short arm into a long arm ) for every cycle.

In the bottom position,we can use an "old key":see the Middle Ages designs,where the long arm "falls down" as a short arm,due to gravity (appears as hinged"). All we need is a single "new key" for the top position,where the short ("hinged") arm must change ("rise up") into a long one...this time,due to inertia.

Greetings Iacob!

Yes, you are absolutely correct! You describe a 2 cycle mode, I use a 4 cycle one (at least for now). I believe JB used a 4 cycle but could be wrong of course. A 2 cycle would be much better!

The 4 cycle implementation goes from commutator engage, short arm lift cycle, commutator disengage/latch to long arm, long arm descent cycle, unlatch from long arm/commutator engage, reposition cycle, commutator disengage/latch to hold arm, hold cycle, unlatch from hold arm then repeat. So four cycles, eight commutation/decommutation, latch/unlatch events per rev per weight.

The reposition cycle has the weights translate horizontally to avoid change in PE so as not to require work to be input for this cycle. This is the "gravitate to the center" part.

All very similar to a 4 cycle IC engine! The commutator/latch system creates the "camshaft" with the appropriate intake, compression, power and exhaust cycles for the wheel. In a 4 cycle IC engine the camshaft spins at one half crankshaft speed to create the correct intake and exhaust valve cycles. Here, the "camshaft" spins at twice crankshaft speed to produce the required cycles.

Hi Cloud !

If you have in mind a common seesaw,all we need is to replace the up-down swinging motion,with a continuously rotating one...nothing more!

Then,if you focus your imagination,I believe you will find some "keys"...I opened some topics about this.

All the best!

Once again absolutely on the mark Iacob! We have essentially a see-saw action that then flips over and continues (just like MT138 shows with the Tippe Topp) There can be just one or two see-saws at right angles. These form the "grindstone" of the wheel and is the only major component actually rotating in the system.

Everything else circulates and translates about the wheel center as opposed to rotation. There is actually no physical rim to the wheel, the weights themselves make up the "rim".

There are three linear weight paths, two horizontal and one vertical, again shown by 138 (although it does show them all vertical). Also, the inclusion of MT139-141 on the 138 woodcut indicates that there are four power strokes per revolution (and four reset points).

The main design goal of the system is to create and rigidly maintain two separate PE systems with different values and keep them totally stress isolated. This forms our binary configuration. We all know that energy can be extracted at the boundary of two different energy fields. Typically it is mass bodies of different temperatures or pressures, i.e. heat or pressure pumps. All we are doing here is establish two different PE fields and extract the difference between them each revolution of the wheel, with gravity acting to replenish both fields each cycle, in effect a gravity pump.

Vertical PE must be paid back in full so no benefit there however rotational PE can be engineered and exploited thru commutation to turn the wheel.

Hi Cloud !

Try to simplify your images.

Milkovic,with his lever with a pendulum made an interesting opening to think moreover...about the variable/oscillatory leverage!

All the best! / Alex

[cloud camper]

OK Iacob, here is a simple image for you.

We can also think of the commutation system as an anti-keeling mechanism. Without this mechanism, our system will quickly destroy any overbalancing we have created and keel to the lowest potential position balancing our wheel. With commutation, the system cannot keel since there is no stress path available with which to transfer weight or momentum to the low PE side. We can see this on the Wheel of Death clips.

The acrobat must continually commutate the wheel in order to remain on top. The instant he stops commutating, he will cause the wheel to keel to the lowest PE position if he is still attached or else be ingloriously thrown off in a heap! Is that simple enough? (just funnin' ya buddy!)

[iacob alex]

Hi Cloud !

In my opinion,"binary" is the commutation description ,also...for two points(180* and 0*/360*).

This seems to be the conditionality for a continuously self-rotation, due to gravity fall and inertia in-out motion storage.

As a whole,we need two "self" commutations:in the bottom position (180*) and in the top position (0*/360*).

For the bottom point we have a very "old key" (a Middle Ages one!),due to gravity "push"...the long arms changes in a "hanging" short arm.

We have so easy the first "self'-commutation!

For the top point...we need some help for inertia ...in my opinion,there are a lot of possible simple "keys".

Easy to note ,that the "PM puzzle",for the moment is "hanged up" in a single point...depends as we solve the top point commutation,as a "self" one...can you imagine this ridiculous perplexity?!

...and the "PM show" goes on...

All the best! / Alex

Fantastic Iacob! You are half way towards realization of the 2 cycle commutation mechanism. It's available to anyone really, and it all
runs in WM2D! I will stay with the 4 cycle version for now as I don't have time for both. Too bad it makes that damn clattering noise! A 2 cycle
mechanism would be a lot quieter! I guess I can just turn off the sound in WM2D.

You mention the time factor in your "Impetus" thread. Totally accurate and I forgot to even mention it but one of the main advantages with commutation is the weights transfer so quickly (in a flash) there is no time for the inertia of the system to respond by keeling. If our system keels, we have given it too much time to react to the overbalancing. The solution is to prevent unwanted reactions by switching the weights very quickly. In this manner we trap inertia in the central "grindstone".

We can again observe this in the WOD clips. If the acrobat commutates quickly enough, the massive inertia in the wheel below him does not have time to
fully react to the changing conditions allowing him to keep his balance.

[iacob alex]

Hi Cloud!

Let's have in mind:
-two equal masses
-a seesaw/lever with unequal arms (one fix,one variable)
-try to imagine a self-rotation,due to gravity fall and inertia...only.

Every cycle needs two quick commutations,for the variable arm ,so to avoid the "keeling" :
a)-long arm into a short arm,in the bottom point
b)-short arm into a long arm in the top point

(here,the fix arm has a medium/reference length face to variable arm: short<medium<long)

a) is a very shortime,but also the oldest "key" (some Middle Ages designs):an "extended"/long arm becomes a "shorten"one (simply a "hanging hinge").

b)here is our point...a quick "jump"

If you like,the rotating seesaw/lever/"Space Wheel"(on youtube...) can be imagined as a variable counterweighted pendulum.

All the best!/Alex
