Gravity Escapement Mechanism

[Grimer]

Having realised that conservation of all the different derivatives of position with respect to time are simply momentum seen from different hierarchical platforms I've looked into the PM problem in terms of momentum only and realise that one can design a Gravity Escapement Mechanism.

One can view such an escapement as a momentum valve, a momentum diode if you like (or as my son, Ben, pointed out, a half wave rectifier) and this will enable you to kill the reverse momentum of interaction between the low inertia and high inertia wheel which leaves just the one direction of rotation.

In his paper THE ROAD TO PERPETUAL MOTION, Hans von Lieven writes:

"The next thing that became clear was that any transmission ratio other than 1:1 was out of the question since the weights on the outer wheel cannot pass the weights on the inner wheel and the system would jam very quickly.

This created a dilemma.

If the transmission was 1:1 why was it there at all? You could just lock the wheels together with the same effect.

...

"Because it is here in that tiny interval over the space of perhaps 20 degrees where he gets cagey."

So we see that there is a 20° play between the High Inertia Wheel (HIW) which carries the weights and the Low Inertia Wheel (LIW) which is the receiver.

Let the two wheels be rotating together CW at some slow speed with the LIW being pushed by the HIW.

A weight is transferred from the HIW to the LIW at 2 o'clock say.

This will accelerate the LIW clockwise at nearly 32 ft/s and slightly decelerate the HIW by virtue of the HIW's resulting lack of balance.

The weighted LIW will move rapidly through the "play" angle of 20 degrees and impact the HIW giving rise to a momentum exchange. This will lead to an increase in the CW LIW acceleration and a negative acceleration of the LIW. In effect the LIW will "bounce" off the HIW. We will assume the impact is virtually elastic (98% coefficient of restitution for the impact, say) and that the energy lost in a single bounce is negligible.

However, the LIW will bounce all the way back to its starting point and keep on bouncing between the boundaries of the "play" angle until all its energy is exhausted.

This is the point at which Hans loses his way somewhat. He writes:

"As the weights transfer the outer wheel gets a violent push in one direction and the inner wheel gets the same in the opposite direction. Since at this point the systems are independent they will move in opposite directions until the slack runs out at which point the forces will clash and cancel each other out. We are back to square one."

The solution is to destroy the return momentum of the LIW - to suppress the bounce. One can do this with a ratchet on the LIW which by acting against the effectively infinite inertia of the frame earth system shunts the bounce momentum off to earth leaving only the forward momentum of the HIW.

The HIW then catches up with the LIW, the weight is transferred back to the HIW and the two wheels now continue on clockwise at increased speed.

I must confess I find it slightly incredible that something as simple as a ratchet/escapement/valve/diode could be the final link in the PM chain. However, when one remembers that the basic element on which digital computers are built is the switchable diode then perhaps it is not so surprising after all.

I have found one of the clearest and most delightful descriptions of the modern computer's simplicity is given by Tim Hunkin in his his Secret of Machines videos. In particular, the three on the word processor.

The above figure represents the angular momentum of the Keenie Wheel and the earth being conserved.

Because the inertia of the earth is so ginormous compared to the inertia of the wheel the angular momentum transmitted to the earth is correspondingly minuscule.

I suppose if one were so minded one could actually calculate it, roughly.

Hi DrWhat

I see your humor and the position of Grimer.
The momentum transfer of the earth too a Bessler device should not be ignored.

If the giant hypothetical gyroscope axis was supported friction-free, so its axis could remain pointed at that specific star, (like on that glare ice) and the Earth was then still able to slowly rotate beneath it, a TORQUE (or Moment) would exist where the Earth could be trying to rotate the fixed axis of the gyroscope. A gear-train might then be driven by the differential motion of the Earth underneath to power a generator or other equipment. Essentially, the Earth's rotation would externally, directly drive the gear train, using the gyroscope simply as a fixed object to push against!

Brilliant find.


I would punch your greenie for that contribution but I find I already have and one's only allowed 1 punch.

That man's a genius. He's solved a far more difficult problem than harnessing gravity. He's harnessed differential Beta-atmosphere pressure.

I've asked him to join the forum. He'll have Bessler wheels whirring away in no time.

(and no, I'm not being sarcastic)

Dear Unbalanced,
Thanks for the very important link.
Another path for investigation is not only the reduction of the flywheel diameter, but also the artificial oversize of the weights. For a small diameter (few meters), you win if your weights are very heavy (a virtual weight of more than 100 tons each), this can be obtained if you observe the elongated arms of the Bessler wheel with attention: do you see why?

[Gwheel]

Unbalanced, great find. Thanks for the post.

I hope many investment groups and corporations have taken subjects like this seriously or we are all in trouble.

About the gyro in a navigation system:

Edit: Add "in a navigation system"

The type of spinning gyroscope, sitting on gimbals, and used in a navigation system which he describes is a bit archaic. As far back as 1985, I was using the then, next generation, commonly called a ring laser gyro or laser ref unit. A ring laser gyro has no moving parts. It is not actually a circular ring, but is a triangle shape. A laser is focused and aligned along the first leg (approximately 9" equilateral) and its direction is changed 60 degrees at the acute angles by mirrors. Using computer controlled measurement and sensing, the "bending" of the coherent light, caused by the minutest movement, is processed to determine both vertical and lateral movement enabling precise navigation on earth as well as extraterrestrial. The ring laser gyro has many advantages over an older conventional gyro. There are no gyro or accelerometer bearings to wear, therefore rebuilds are not required. With no bearings to wear, there is no gradual increase in precession inaccuracy. The accuracy is far superior. They are expensive, commercial units of aviation or maritime quality exceed $100,000. I don't want to consider what the US Navy pays for triple redundant systems for submarines. Then again NASA uses them also. For our purposes they have one glaring fault: You probably can not drive an energy producing machine.

Hereafter is a drawing showing a particular design, like two umbrellas back-to-back in a vertical plane, and analog with the Pr Laithwaite flexible gyroscope.
The left half part is a view from the main axis where the cover of the wheel is removed.
The right half part is a cut view from the horizontal 9:00-3:00 plane (like in the Bessler drawing).
The assembly is made of sixteen (2 x 8) horizontal torsion bars, colinear with the main axis of the wheel and located inside the two elongated arms.
At the pillar side these bars are soldered to the elongated arm circular end cover, itself soldered to the main axle (the pillar is not represented).
On the other side (in the inner of the wheel) theses bars are soldered to one end of the iron spokes, the second end of each spoke supporting a single weight.
This 90 grades redirection, in combination with the spring effect multiplying artificially the centrifugal force, allows us to obtain the same effect than with an 1000 times heavier weight.
The bending of the spokes have been exagerated.
The torsion bars make slower the uprise between 6:00 and 9:00 and gives an impulse between 9:00 and 12:00 because the strong torque of the torsion bars.

There are some springs, but not used like you think said Bessler.

The solder is perhaps the reason why Bessler is referring to the alchemy or to some chemical elements.
It could be interesting to study what was the consistence of the solder in his time, when you want to solder two iron parts (may be analog with today's method for the exothermic soldering of the rails for the train railsways). See here: http://en.wikipedia.org/wiki/Thermite

Returned back home now (and after completion of my final reports) I can restart my experiments within few days. I will build one, just for view of what happens.

... but I was being wildly optimistic.

Unfortunately someone contacted him at the same time (from the forum?) and queered my pitch somewhat.

Still, nothing like leaving no tern unstoned.

Because the inertia of the earth is so ginormous compared to the inertia of the wheel the angular momentum transmitted to the earth is correspondingly minuscule.

Of course it is not really necessary to use the whole earth to act against. One could simply use a large inertial flywheel and by gearing use any energy put into that flywheel to add to the energy of the High Inertia Wheel.

One would be using a similar strategy to that used in the double acting steam engine.

Pendulum Demonstrations (14 links in 1)

According to a 1999 Gallup poll, about four out of five Americans (79%) correctly respond that the earth revolves around the sun, while 18% say it is the other way around. Oh shit, those 18% get to vote! By the way, the results in European countries are in the same range.

If you still have doubts the earth rotates... well, it does. "It actually took centuries for scholars to come up with scientific proof of this fact. In 1851, the French physicist John Bernard Leon Foucault discovered that a pendulum swing plane would precess according to the earth's rotation." (See link #6; Foucault Pendulum)

In the video, the announcer is ignorant (he did not correct his misstatement) but he is likely just reading a scrip with a typo, using the word "process" when in fact the word is "precess".
