...is the real problem.So, vs.=versus,you can find in "Webster's Dictionary" as "in contest against,in contrast with,by way of alternative to...". The problem,introduced at this forum topic, was "wheel vs.lever",or lever in comparison(facing,in exchange for,opposite to,contrarly to...) with wheel.Most people think(or dream) about "something" as a self-turning wheel due to gravity.Few people,as I know Bessler only,designed and accomplished a different concept:a lot of unequally levers that balance in a certain manner on the spokes of a wheel,so that this one is self-moving in the and owing to gravity.So history tell us and Prof. Evert( www.evert.de ) explains in a so clearly,inteligible german thinking manner (text,drawings,animations) this case:wheel and lever(s) concept.Now,our friend, de Lanca ,I have a question:you know about Knapp and Bierner...what were their concept?Wheel(1),wheel -lever(2) or lever(3)?My proposal was "lever only"!By the way,as an "old sailor" I have some sheltered ancorages,safe waters...Smile!All the Bests!/Alex
...seems to be this wheel concept on our endeavour to imagine a gravity power pulling out mechanism,device.Really ,the gravity,this natural rush,overflow,cascade is setted in a very "difficult" situation when "meets" our wheel type arrangements,a kind of no more that stable balancing "traps"...useless regarding to our expectations.Gravity "rapids" property has no time to manifest his impetus(m*v):we have the balancing mass(es) on a comparating tool,as usually ,but with no velocity.The outcome is no impetus.It's a weighing machine,nothing more,a failed "start" for a self turning mechanism.A proposal,a solution can be to set free impetus,thinking about an other,unlike aspect of the weighing mass,comparator.As in electricity we need that momentary surge in one direction of voltage or current,in mechanics we demand for that "unseen in the air" change in momentum effected by gravity about a mass,by the TIME during which it acts.So,let's free the gravity momentum... can it be a manner to understand clearly,to achieve a turning gravity "waver"?Who knows?Usually we understand what we know,only.That's normal in our transitory life:a patient attention ask for time...All the Bests!/Alex
...that old "dream" of mechanics, is a little like the swing sets you might remember from our springtime of life.Swing gives us an emotional,sympathetic contemplation to this gravity...all life we live in,a feeling of a kind of real flight...in an amazing, ineffable,beyond words medium,environment... but in a controlled manner however.You can play pendulum,alone or lever,with a playmate:you pump your legs,so to increase the height of the swing's arc(you can make it as a circle...with some bravery,tenacity),that's all.Simply thinking,it's like we charge-discharge ourself with "something".In fact ,we perform a lever concept:a fulcrum,a bar ,setting side by side in comparison two masses:one "fixed" and one "mobile".If we can swing "on the spot" , why not imagine a lever rolling in the same pattern, pumping some "leg"?I said rolling,so for a full round,circular "trip"...we ask for some help(impetus) in a line that falling power>lifting use up.That motion of "pumping legs" can be transfigurated,reconstructed in a "pumping lever",or playing elementary mechanics.Gravity exibits in a restrictive path:downward only.We can fall in many ways,inclusively on an inclined plane.If we want a self-pumping alike motion, regarding a swing-lever style,let's place the moving mass on an inclined plane ,so that at the bottom position,it falls to the fulcrum(brings about the short arm R1) and at the top position,it falls from the fulcrum(brings about the long arm R3).This switching mass M1(and arm) has a fixed arm companion mass M2,positionated at R2 from the fulcrum and R1<R2<R3 , M1=M2.Now,can we have a rolling lever on the spot?Can we make it self?Let's hope!All the Bests!/Alex
...creatures,animals,human beings is a far away,general viewing regarding the change of place,movement on our Earth.The inverted pendulum on a surface,flapping motion in the air,undulating pendulum in the water.During walking,the inverted pendulum equivalent of our mass-body ,moves like a kind of a "sectorial wheel":with each step cicle,beteen two gravitational levels,some of the gravitational potential is converted into kinetic energy ,and then back.It's a walking pendulum .Energy transfer in a gravity environment is made in a pendular manner.Can it be a suggestion for our topic,in this "wheel vs. lever" dilemma?All the Bests!/Alex
...tools,devices,vehicles,gadgets can utilize ways and means to transfer a natural point of view regarding energy and transport(swinging,oscillating,wavering,unsteady,undulating so many aspects,faces,properties of the same physical pendulum) to our understanding and use,applicability,serviceability and benefits.Try to think and see the inside pendular "skeleton design" of the world around you, at so many beings and things.As simple as possible can be a basis ,a groundwork to set up,build,assembly our knowledge and mechanisms regarding the topic at this forum section.Considering the choise(my dilemma...) "wheel vs.lever",my option is lever(counter-pendulum,Roman balance or steelyard slightly modified,bended).All the Bests!/Alex
...if we "remake" the Poggendorf's classic lab-experience(and apparatus...):lever instead an Atwood machine.So,we will have a great lever with a fixed (2M+m) mass at one end ,and with a small free pivoting /rotating lever at the other end(as a replacement for the Atwood machine),loaded with the same (2M+m) mass.Usually this arrangement is stable.But ,supposing that we set the two diametrally positionated masses on the small lever,as (M+m) in the top position/(M) in the bottom position,we determine an unstable state not only for the small lever(let's say on the left arm of the great lever) ,but for both.So,the left arm of the great lever(supporting the pendular motion of the small lever),will move up.The system becomes accelerated due to gravity: a double fall chargeable to the same linear "g" ,this time variable acceleration ,owing to torque.Can this case generate a question "family of IF..." regarding our topic?Maybe.All the Bests!/Alex
Hi ! It can be a point that, this forum takes into account the real success of Prof.Veljko Milkovic.This news, for a time, is old for people that have in mind a lever,not a wheel,as a possible "key" for "harvesting" gravity flow on an inertial frame("scenery"):this two stage mechanical oscillator, was presented and won a gold premium during the 2002 fair in Novi Sad(patented in 2001).Tesla was from the one and only country...The problem is that ,anyone can "fit" a lever and a pendulum in the same way,to "remake" this "excess" energy device.The next step,you guess is a feedback...but ,in a final ,I bet:this will not be a "wheel",but a pendular lever with a store-restore energy system.The most important fact is that Prof.Milkovic ,with this "key" opens a wide vision regarding the interplay of action-reaction phenomena in mechanics, that of nonlinearity.The action has a so large meaning;you can "beat"/force or you can "sing"/oscillate a medium(air...),including inertia.Let's say that I am a dreamer,only.All the Bests!/Alex

Hi!As I can see the things,if we are really interested to get a gravity engine(a machine which produces/interfere,acts as a drag in a natural energy flow /so to power our working necessities),we can think in the terms of an external gravity "fire" engine.The term "fire" is so extensive,it can be combustion,flame ,flashing light,energy,vivacity...in the forrest of the word-trees,we have a multitude of pointers and connections.The short way,so to detect a possible design for a gravity engine ,is to re-think the Stirling engine,with new twrms.We have the skeleton,the frame-concept design,ready to be restored from the thermal to a gravity consideration.All that we need is a translatory reasoning and practical operation.In a commonplace language:play a lever("high pressure" due to energizing free fall) instead of a wheel("low pressure" due to a weighting measurement) concept ,if you are intended to start a self-gravity engine.By the way,that's the first rule for an operating engine.Like you set moving,igniting a flame:the same spring out of energy.A little experience from our ancestors often upsets a lot of theory.All the Bests!/Alex
Hi! The essence of an engine(with an internal of external "fire" source) is the high pressure on the piston.If we consider gravity as a "fire" source,in the most comprehensive manner,a possible gravity engine can be imagined in two ways:in a wheel (many spokes) or in a lever (two spokes) configuration.By the way,a lever can be considered as a "minimal wheel" symbol.A wheel concept,as consequence of a linear comparative operation ,about a geometric unbalanced,asymmetric design(intended to be "self") vis-a-vis a vertical line(gravitational fall reference),results in a "low pressure" or physical strain,tension,an equivalent long arm-short arm lever difference multiplied with "1g",that acts as a weighting machine,swinging a little,around a balanced position,no more.Really we play statics. A lever concept(two spokes,arms) attests a free fall time for the long arm(raising the small arm,in the same time),and so we have a nonlinear comparative operation about a full pendular motion,resulting in a "high pressure": a single long arm-short arm difference multiplied with a "greater g"(remind "falling chimney" effect and 'falling stick" lab demo ).So,if you want to start a gravity engine,play dynamics ,let it fall,so to get "high pressure".Stirling engine can be a relative of this one,as a concept.this is my opinion...Simplicity is the first step,curiosity and understanding come after.All the Bests!/Alex
...can be a shorter expression of the wheel versus lever dilemma,as a starting point to imagine a gravity engine.We have no proof in reality,about any of them ,as a thinking manner to achieve this aim,so the one and the other,have for the time being,an equally status.Again,I come out that,we are living inside a huge natural mass accelerator,an enormous energizing system.This one,gravity,is not primary to inertia(Lex One/Newton),so we can consider it,as an interface to inertia.Inertia,by all means equilibrium;constant velocity,no acceleration.Or "let's the things as they are and as they move".If you want to act in a some way,you need acceleration(Lex Two/Newton),that is change of velocity.This change of velocity,we have for free in gravity.Newton enlightened us,what to do,if we want to change something:to accelerate.When we increase the velocity of mass,on the horizontal line,we must pay for it.On the contrary,on the vertical line,the increase of velocity(falling mass),it's for free.But ,this fall asks for time,so "g*t".That way "g vs. g*t" can be a kind of "to...,or not to...",as you like to understand.All the Bests!/Alex

Thank you for the enheartening;as you see my "flag" is pendulum for a gravity engine.Some people are imagining a wheel(many spokes).In a way,my concept,a counterweighted pendulum(an unequal lever with two masses at every end of this one) is a "minimal wheel',with two spokes ,only.The problem is that a wheel with two spokes/a lever in fact/ allows a longer time to fall for the driving mass,so to accumulate a greater velocity V=g*t,in this way a greater acceleration and momentum:a mechanical unloud,similar to an electric discharge .That's my opinion.It is the difference of opinion that makes the things to advance,to step forward.Best Regards!/Alex

I live in Australia but was born in the region of Srijem,
My Garage/workshop has been undergoing a major change/renovation for the past three months and is now 95 complete.
I plan to build and test a whole new design soon. The main internal feature will resemble a banana in the form of a bent pendulum attached with springs and using miniture servo's for tilt speed. Movement of banana pendulum will be very restricted thereby increasing rotational speed once already in rotation (non self start) other mechanical hickups will be addressed and should be a minor issue if all goes well. Looking at late January for first prototype test.
Issuing a success rate of 15 %

hi iacob alex, I've seen your stellarotor website a few times before. It's very nice :) I was thinking it would be nice if you put 1 image on a page and write something under it. Even just a url would be cool. Then one can link to one. The images and photos are a bit to small, I imagine you didn't keep the originals? You can (however) try blow them up a bit with irfanview or the gimp. Could also try some cropping to make them more clear. I assume they are your drawings and constructions, your view on things is quite original would be a waist to waist it. :)
About the "wheel vs lever", I've been calling them unbalanced wheels for some time now. It's like a lever also being a wheel.

Hi Gaby!I made a short visit to your web site:it's interesting,and I will return again,so to get some possible suggestions.Thanks, for your nice words.For a time,I am not living on my basic residence,so I can operate with messages on net,only.In a way,I am not an handycraft man,I prefere "paper and pen",so to pass over,explore the huge soft forrest/aquarium like a monkey/fish ,in short and rapid lonely jumps/tours.About my web site,I believe that an elementary drawing is worth more than a lot of words.We are living now,sometimes,a time of simulations,a kind of Jurassik Park Science,on accasion, as you can see on net.For this ,I prefere the old Middle Age style designs:it's open,with any ruse,trick.By the way,my web site is old.What you can see at "Related images",now are stored in a cellar...waiting to be disposed at the garbage.Long time ago,I put aside on the fire,a half thousand designs about PM...as to escape from a burden...then,my conclusion was that in a "quiet lake"/gravity we can't imagine any self moving wheel,device.After years and years,thinking about IP/inertial propulsion(again about a thousand of designs...),with a new image regarding gravity(sometimes as a quiet lake,sometimes as a huge energizing flow ) and about the fact that ,the mechanical world of dynamics is playing on a double stage(basic inertia and gravity as an inertial "discontinuity"),again I tried to imagine the things in a different manner.This one,was discovered in one remaining designs of the past time.As in life,in a long travel,you are determined to carry what you need ,only.Sometimes we throw some things,that we really need,but the mind is a different storage:virtual.So,the memory can help us.All the Bests!/Alex
alex,
just for your information, the first time i ever thought about overunity was when i was twelve years old, and my father was working on a nuclear power house in america. i got to take a tour of the facility, and i had to wonder, why didn't they just take the energy from the first round of steam that made electricity and use it to heat the boiler from then on? then just use the extra energy to sell?
i was told then about the laws of thermodynamics! what a crock, is all i can say, even thirty years latter! i don't think any of them actually tried any of the experiments, they just, "BELIEVED"!

...can make us think about a facile setting side by side.
Any design that takes into account a wheel (many spokes) or a lever(two spokes only) concept is equivalent,with a fall in gravity that follows a circular,or curvilinear track...a particular inclined plane.
The most noticeable characteristic of gravity fall (this "invisible flow"...) is his nonlinear development with the time factor: "g" is a constant acceleration,so we can get on this inclined plane, an ever increasing velocity (kinetic energy)...if...we let it fall rather more time
In this situation,the lever concept seems to have a certain advantage....
All the Bests! / Alex
...as a concept is on the line "why make it easy,when you can make it difficult?!"
Or more matter,less art.
All the Bests! / Alex
...concept , setting side by side,becomes essential ,when we take into consideration the measurable quantity of movement,that we can get out ,due to gravity fall.
The hub and the spokes,usually are figured as a common,rigid body that can rotate in a single manner: with a collective angular velocity.
The hub,adds the effort of all spokes.
The contribution of any spoke is variable,not only owing to the momentum's arm ,but especially due to their free fall velocity.
Here is the point: in any sequence of the process,the spokes ask for some individual angular velocities.
In this way,instead of "an army of one" effort,we have "a nonsense stampede" stess : at any time,some moments are pushing,some moments are pulling....and their possible summ working effort, becomes smaller.
Here we have a "to be ,or not to be " problem : before to discard any "wheel concept" design(more than two spokes),give them the last chance,that of two spokes only.
All the Bests! / Alex
why wait for gravity when you can create it in revers, any amount. Centrifugal /centrepetal force is like gravity, only backwards/ inside out. with Cf, you can manipulate alot of variables that you cannot with gravity.
Hi Cameron !
Your question up-there can get a multitude of answers...
My answer is this:if in the future we will be in a different planet(like Mars...),with no other flow(do you said rivers?),but gravity, we need to know how to take out power from this only source...
All the Bests! / Alex
Hi !
Ok ! Let's say that this topic ("wheel vs. topic") is not substantial for us...
Then,thinking that a wheel concept (or a lever one...) is made up,in a possible elementary design,as a repetitive addition of a certain number of identic spokes to a common hub,we can simplify our "search"...
Now we have a single and final "minimum minimorum" type question:how is a spoke,a single one...
This is all what we want,nothing more...
All the Best! /Alex
...as a face to face concepts counterpoise,to imagine a possible gravity device,is similar with the purpose ,to take away some power from a "frozen river" vs. to take power from a "free falling " spring/flow .
For any wheel design,the free fall is allowed as much,as the distance between two successive spokes :more spokes,less free fall.
For any water/wind mill,the first requirement is to have a free flow...
For a gravity powered device , we have the same dependence !
All the best! / Alex
......can be a "PM dilemma",in my opinion.

.....or playing gravity with a wheel concept , as :
www.energythic.com/view.php?node=264 (http://www.energythic.com/view.php?node=264)
I tested the concept of moving the arm/weight 90 degrees in line with the wheel and it does rotate because its mass is shifted from the axle. I call that the "set" and then after it rotates less than 180 degrees a "reset" must be done so it is re-balanced and no work is required to get it back to the top for a repeat . So I call that "switching" and it would have to have more energy from the rotation than the "switching".
I made something similar where a smaller weight with leverage raised a larger weight upward from the axle as it tilted and went past noon and did rotate about 100 degrees but would not continue. Then when those leveraged weights got to the bottom it reset itself....
Norman
Further analysis and testing shows that "setting/switching" would have to be done on the fly at 12-1 where the greatest leverage is available and then "resetting/switching" back to balanced at about 4:30 so the weight does not go outside the circle of rotation causing work loss to lift it back up to its balanced position. I am sure Finsrud could finesse this well.
I will do some crude tests to see if it is even close to possible.
I have a second mechanism that could do that without any inertia losses...
I have always said it will take multiple mechanisms to work together to have a gravity wheel successful.
Norman
The latest test takes the weight from noon to 9 pm but when it goes past 4.30-5 the weight goes outside the circle and would take work to lift it back into a balanced position. Now the hard part is to get the switching to work with the power that is created from the rotation/leaning. Indeed it is a very clever idea to avoid the losses in the reset.
Norman
Using crude measurements
1. set One nut moved horizontally 1.5 in. with less than 1.5 units of work
2. lifts an equal nut 5.5 in 366% OU
3. reset 1.5 units of work
giving a minimum of 183% OU.
So manually one marble would lift another marble 5.5 units and 1.5 units of that work out could reset the machine to repeat the process.
But I would guess half a marble would move the marble horizontally increasing the OU to over 600%.
So picture this. A marble machine where you move the marble to do the set and it lifts another marble 5.5 inches which can then be partially used to reset and move the arm back so its balanced. You then do the reset and then the set and all you have done is roll 2 marbles horizontally to make at least 3.5 units of free work.
As my neighbor says "There you have it".

.....ou jouer à la gravité avec un concept de roue, comme :
www.energythic.com/view.php?node=264 (http://www.energythic.com/view.php?node=264)
It was a friend of mine who made this sketch, which has since disappeared and was plagiarized by this site. there are a lot of TDCs on this planet!!. It's a wrong direction, the imbalance of any kind can never reset, and that's logical, forget Newton's laws, just experiment, it's never going to work in this direction, but there are others.
Thanks for sharing this method. It has lots of merritt but what I have found is that when weight is shifted as in this case just past noon that half of the wheel becomes bottom heavy and that has to be corrected before it gets to the bottom. And usually one thinks that adding more weights will fix it but I have found that often it reduces the work out because now there is more mass to move.
So my current effort is to add something to undo the bottom heavy problem before its too late in the rotation. But without some clever geometry it will counter affect the rotation.
Currently I do not have a wheel but a "seesaw/pivot/rotation" that works best in reverse of the drawings.
But the great point in this design is that it has a smaller "reset" loss than other designs I have seen and worked with. When the shifted weight starts the wheel to turn the "reset loss" is not near zero unless the weight is at the bottom and with a wheel in motion that would be tough to time correctly.
I am only using 2 weights/arms

.....but playing the same up-down hinge idea (variable arm...).
As a matter of fact , we can play a possible continuous gravity unbalance with minimum spare parts :
-fulcrum/pivot
-lever
-one or two up-down hinges (one or two variable arms ).

Hi guys!
Very nice drawings Iacob. I once had calculations for gravity motor prove of work according to existing physics, I need to remake them again. In such calculations you divide motor in two sides. Then you calculate left momentum (torque) and right (according to forces and arms). The principle is that the right torque is always higher than left torque that creates difference (free force) to move the motor. All this energy comes from gravity and is possible due to right build.
All what You have drawn here is unbalanced mass which creates torque. You can do such calculations at your own for any gravity motor. If the torque is higher than friction than this will move perpetually.
Hi !
Rising butt hinges are used to aid doors to SELF close ...due to gravity..
Rising butt hinges ...if used in a "upside down" doors position aid them to SELF open...due to gravity,also.
Rising hinges cause the door to rise around 10,5 mm over 180 degrees.
We can use rising hinges for a wheel concept ( see Maillardet's wheel with masselottes ).
We can test the lever concept ...if we add a rising hinge (only one !)...so , playing a lever with a single variable arm.

I have have 3 embodiments of the Mallardet concept. Two arms and one wheel. And only one arm performs well - rotates 270 degrees. The geometry is a little different but I have added my own mass shifter that gravity sets and starts the rotation and gravity resets back to balanced.
In the unbalanced mode it acts like a pendulum that self resets at about 160 degrees.
As you know pendulums do not rotate 270 degrees.
I learned 20 years ago when I have something working "freeze it" as is and make another one. So today my goal is to get the 2nd arm working well so I understand what makes it perform well.
I have replicated the 270 degree rotation successfully. And expect to get it on YT tomorrow.
It starts horizontal with a leaning stick holding it steady and ready to start when the camera is ready. Then I kick the stick out so no one can accuse me of adding to the rotation. Then gravity shifts the weight and it rotates past 6, 9, 11 up to noon.
and then comes down and rocks like a pendulum.
So were did that 90+ degrees of rotation come from.
It may have some Skinner effect as seen here

No. I had also something ten years ago. I do not return this something,because I am afraid that it will be simple reason for my misconceptions. A simple reason why it could work without breaking the laws of physics. I want to believe in a dream. At least it was honest.
The YT video is here and is described.

Hi thx4 !
If we correlate our image/design with phenomenon ( gravity potential and rotational inertia...v=gt and KE ) , increasing the radius/gravity potential ...can we manipulate so easy a self reset on the top position ! ? Maybe...if you take a look at :

Without a proof/test , this is for the moment a confusion or an uncertainty about what is happening ,only ?
Simply : if we make it bigger ?

Why don't they use this principle for drones? And for carrying small loads ?
Birds spend less energy to move the same load over a given distance.
