.....is on the line or can be a manner of (re)thinking about a possible gravity powered engine , if we take into consideration an old Middle Ages (~1705) machine , at : http://en.wikipedia.org/wiki/Beam_engine (http://en.wikipedia.org/wiki/Beam_engine)
All we need to do is simply , to replace the "wprking push" : the steam with the gravity unbalance (torque difference).
As a matter of fact , we can rethink the constant beam as a variable (leverage) one.

Greetings, I am working on a similar project on a small scale. I plan to use a PMA to charge a cap and have a cam on the drive shaft trigger a discharge to a pair of electromagnets for a positive feedback to the system. I still have fabricate the beam and the unbalance flywheel. I can fabricate gears to use for shifting the weights on the flywheel. If you have any ideas that will help, I can fabricate it for testing. Thanks for posting your project.
Hi !
My domain is to play gravity with a lever ("beam").Take a look at a net archive :
www.geocities.ws/iacob_alex/Some_Drafts.html
Maybe...it can help your planned project.

Hi, you have a lot of interesting ideas. Thanks for posting. I completed the gear set to shift the weight on the flywheel. I plan to start with the most basic configuration. One weight will be stationary and the other weight will orbit in a eliptical path. Starting fabrication of the beam. Will post results after fabrication. Thanks again.
Hi, I fabricated a quick frame to identify the problem areas. The biggest problem is I need the electromagnets to trigger at 0 and 180 degrees. The mechanism will only allow for triggering at at 90 and 270 degrees. Is there a mechanical configuration that I can use that will help or allow the trigger location to shift 90 degrees. The electromagnet are pulsed with power so they are on for only a short time. .

Hi 0017 !
What is the starting image/idea of your "Magnetic" build-up ?
In my opinion , everything should be made as simple as possible for the first test , because...the whole is simpler than the sum of its parts.
Anyway , I wish you success !

Hi, basically I am fabricating a large steam engine. I did some experiments with gravity assisted power last summer. From what I observed the projects I attempted needed additional power to work. So I was thinking maybe adding some kind of feedback would help. If it works, great. If not, I will have other options. PPMT maybe the solution, inverted electromagnet. But one step at a time. Yes, simple is best but this is the only way that I think of to fabricate and add feedback to the system.
If you want to use weights to balance out energy over parts of a cycle, that can work. The available energy and power densities are poor doing it that way. You might have specific reasons why you would go that route rather than using other means such as the venerable flywheel.
.....is an elementary proposition. It has as a natural "datum" , a short movie , with an "unseen beam/lever " , if you take a look at :
www.youtube.com/watch?v=uGBANgbRkws (http://www.youtube.com/watch?v=uGBANgbRkws)
It's a continuous self-rotating balance.But how a continuous self-rotating unbalance?
Try to play the barycenter on the same side of the fulcrum , as a variable/oscillatory leverage...
Maybe , regarding the topic of our forum , we must go again and again to nature for information...this time as an image , the concise expresionistă of communication.
Al_ex
Those observations won't be particularly useful for any machine of practical size on earth due to the huge mass disparity.
Hi !
If we intend to "copy" the natural model of a "perpetuum mobile" ,we are living on , we need to use two mathematical relațions ,only :
- constant mass ratio M/m=81 (M-Earth vs. m-Moon )
- variable arm ratio l/L =....(l - Earth CoM vs. L- Moon CoM to the common CoM/fulcrum ).
If we intend to obtain , draw out some "useful" motion for "free" , we need to maintain in some manner the common CoG on the same side of the fulcrum/support.
Simply , we can change and play a well balanced self-running system into a controllable unbalanced one.

Hi, I changed the feedback to use a magnet piston. Promising results, proceeding with fabrication.
.....is intended to be , as a starting image a simple mechanical arrangement , playing variable/oscillatory leverage (a beam/lever+two masses) , or a continuous unbalance on the same side of the fulcrum.
For the present moment ...I have in my mind no magnets.
If we play gravity unbalance , the size can be comparable to a steam / heat engine :

...but much more simplified.
Their common point is the beam / lever ,only.

Hi, I found this flywheel configuration on youtube. I just completed fabrication of the device for study. Converts reciprocating action to circular motion. It creates some interesting possibilities. Maybe use a pendulum to drive the device.
Hi 0017!
Not related with a "Beam gravity engine" , but with your test , take a look at :
https://m.youtube.com/watch?v=x0bWcmxq704 (https://m.youtube.com/watch?v=x0bWcmxq704)
Here you can see an erratic eccenter with three masses.
It's a replication of an old test (Felix Wurth...some details at www.evert.de (http://www.evert.de). )
Take a look at : www.evert.de/eft377e.htm ...playing two masses,like your model.
It can help us to make some understanding of inertial propulsion.
In my opinion a possible gravity motor have a close resemblance with a future space drive propulsion.
Al_ex
Hi Burnit0017,
Nice build, it's similar to M. Kanarev's work.
Attached is a possible way to maybe extract power from it. The tricky part is getting power from the system the load will have to be evenly distributed between the two generators or they will unbalance each other.
.....is the particularly proposed name of this topic.Here we can have three questions :
-where is the beam or something alike?
-how plays the gravity ?
-what is the primary design/principle of this possible kind of engine ( converting gravity potential energy into mechanical motion) ?
So , we are "beaming" ,following like a radio beam, as an aircraft ...to gravity or to variable rotational inertia ?
All is basic mechanics , nothing more...in my opinion.
Al_ex
Hi, thank you to everyone for the added info. I plan to add a drive gear to the support arm to drive a PMA with a MPPT circuit at the output. I will use a double pendulum with electromagnets to oscillate the crank. I am fabricating the support frame now and will post results when available. Thanks again.

Perhaps it can be like this:
1. have a massive balanced beam
2. make it unbalanced with a tiny weight
3. make other end to accelerate to a considerable speed
4. transfer a momentum to a generator
A tiny weight on one end will create a huge momentum on another end(m x v)
the device of feliz wuirth, living machine.
does not work, it does not even have a tappable shaft from what I can see.
The Device of Kanarev, unworkable, it needs impossible clutch.
a device wich is basicly the reference in terms of gravity devices was the chas Campbell
from my research, was a legitimate device.
http://www.overunity.com/12464/using-chas-cambel-flywheel-system-for-15-horsepower/135/#.U_qAU010y70
From the sims i did, if we add a small, hidden, eccentric, we can have rocking motion wich is = to rotating frequency, if the frame holding this rotating mass is somewhat loose.
It is my belief, that this switch flywheel is trapped between loose( pulleys) , wich allow it to oscillate by translation just enough to be energized by drive motor and squeeze the the pulley powerfully and fast, avoiding connection of input to ''filter wheels'' if possible When such force of applied tangantially at 1000hz, the lead out theory happens.
I believe that this attempt is quite obvious with chas first video, but that others, are batter @ hiding this oscillating tension on the belt.
The Turkish company is a perfect example, you cannot visually notice the rocking. but their assembly indicates to me that their tensionner needs to be tuned.
Hi, added power output gear and more mass to the support arms.
Relationships I have noticed:
1.greater mass on the support arms the smoother it operates
2.counter torque most be applied to the crank as the planet gear mass moves toward the center and released as the mass moves
away from the center, if timing of the counter torque is off it start to stall
3. will not operate if the support arms RPM is slow
For this device to be useful, it is going to need a controller board. Two inputs, one to read RPM's of the support arms and one to detect the position of the planet gear weight as it starts to move toward the center. Two outputs to control the electromagnets that will drive a pendulum that will be connected to the crank arm. There maybe a purely mechanical solution, but I can not think of it.... Controller board will be a good winter project. Suggestions and corrections welcome.
.....is an attempt to open a topic about the possibility to imagine and test the variable/oscillatory leverage with / of a beam.
Take a look at : https://m.youtube.com/watch?v=kRW0ASuBrdc
If this design is unworkable...can we imagine and test a workable one?!
Al_ex
Hi, making progress. I still have to install double bob pendulum. Using overrun clutch to drive main flywheel. If you want me to start a new thread please let me know. I think the problem with the design you posted is it will find equilibrium and stop.
Hi !
This is not my design ; somebody ( Kojin ?) posted it on youtube.
It does seem to be a not-workable one (a test can be conclusive)
My challenge was: playing around this simple idea , can we imagine a workable design ( and test...) ?!
The common starting image can be : a self-swinging seesaw , due to an alternate gravity unbalance.

Hi, a short video update identifying problem areas. I am planning to add a second symmetric weight to each planetary gear and increase the gear ratio of each planetary gear so they function more as gyroscopes. Then the device will act more like a standard flywheel with the added benefit of precession. It should also solve the input timing problem with the pendulum.
Hi 0017 !
This thread was intended about a possible gravity powered device ( see the main topic...) , if we start with a fulcrum , a beam (lever) and a certain arrangement of two masses , so to play variable/oscillatory leverage due a continuous gravity unbalance , on the same side of the fulcrum , nothing more.
As I see , you test a personal mechanical contrivance (as Felix Wurth and others...) ,aiming to manage some centrifugal effects for ...?!...maybe to deal with a controllable tractive vector ...so to use it for...?!
One of the secrets of the life , is to keep our curiosity alive...so , I wish your success !
Al_ex
Hi, thanks the for info, I will start a new thread. Thank you for the help. Cheers
.....as a manner to simplify our imaginative attempts for a gravity ( "self") powered device , at :
www.youtube.com/watch?v=Upp-Xr5JAg0 (Remzi Eyupoglu)
Somebody ("veproject 1") made a test at : www.youtube.com/watch?v=c9YLkoJz7rM
...working/rotating for a while , due to a starting push.
They play a beam/lever , with two equal masses/equal arms ( a centered body ) and a pendulum ( an eccentered body ).
Easy to make a simple "cut" of the up-here design and to test it...if we play two masses /pendulums /eccenters, only on the beam.
It does seem that , due to a continuous gravity unbalance , on the same side of the lever's ffulcrum.....it's a "different" game

For your information:
All types of machines like this or other which is suppose to work without input, will find equilibrium and stop.
Also, feedback loops or assistance of any kind needs energy to be taken from somewhere. Taken from the machine itself will likely cause the feedback source to be fed by the machine itself. How do you in a closed loop determine where the energy source, feed backs, or assistance is coming from? Can you determine in what "direction" the energy is flowing in a closed system with no energy input?

.....so easy to test , has the shortest spare parts listing :
-two beams
-a byke's pedal crank
- two fulcrums
So, can we play a possible self running Class 1,2,3 oscillatory leverage?

It's easy to test, but I can't see that it's neccessary. However, I cannot stop people from trying. Last time I made a trip with my bicycle I really had to work those pedals all the time. No free ride :-)
.....is a possible second class lever simple machine , playing variable/oscillatory leverage , as follows :
http://imgarcade.com/1/second-class-lever-simple-machine/ with :
-Ld=constant
-Ed=oscillatory(to and fro)
We need a pair of counterbalanced beams , playing variable length ( Ed ) for simply supported beam , due to a Class 1 lever collecting the unbalance.
Al_ex
.....has a very old "ancestor" , playing variable leverage , also :
www.nubian-eco-village.com/example-of-a-working-shaduf/ ...see the short movie
Every simple machine playing gravity has something "very ancestral" : the lever.
Al_ex
.....if you make a connection with a lab-demo ( Loaded beam - moving scales...or variable support point ) , at : www.physics.uci.edu/~demos/images/Demos/1j10.30.gif
Effectively we can test a continuous unbalanced leverage ( a pair of beams with a variable support point, and a Class 1 equal arms lever ).
Science is sometimes perception , or simply common sense but the certitude is one thing we can't get without a repeatable demonstration/test.

We need to maintain the "flow" ( due to a continuous torque unbalance on the same side of the fulcrum) between two gravitațional levels and to supply the "top reset"/starting unbalance ( due to a flywheel/motion storage ).
Practically...we slow down free gravity fall/"flow" between two gravitational points/levels ...with an adequate "wheel"/lever into an unseen river/"flow" ...
