There isn't really a theoretical limit to the idea just a limit for each weight and radius difference combination.

Another thing to consider is the effect of having the movable weights moving perpendicular to the direction of rotation. If you get even slow rpms out of this thing it will vibrate horribly. If you want smooth motion you need to move in the plane of rotation and you need to do it as smoothly as possible. There are of course practical limits.

OK, how about this: make the spokes 2 rods that acts like guides for the sliding weight. The middle section of each weight is a roller. Put stationary ramps at the top and bottom of the wheel fitted in between the guide spokes. Make the ramp curved so that as the weight makes contact it is always rolling down the ramp at the same angle as it travels either up the guide spokes or down them. That could be a way of moving the weight back and forth on the spokes, but how do you keep them in position?

@nwman - Now that I have seen your video, I have a better idea of your system. I noticed on your second try when you manually flipped several magnets to initiate the rotation, the top magnets did not flip due to the constant speed of over-travel. I think you may need to add another stationary magnet to the top and bottom, not to increase the magnetic field but to make the field longer. As the speed increases the time in the field will decrease making the flip harder to achieve.

Before I saw your video, I had an idea on such a system as shown below. Of course the distance of the A and B magnets must be ajusted to allow minimum sticking while assuring that the magnets are raised. I also added a speed adjustment lever that changes the inner and outer magnet positions to raise the rotating magnets later in the rotation.

mgh "dilemma"...
« Reply #82 on: November 19, 2006, 08:04:56 AM »
...can be an other point of view ,regarding the old  and classic "interdiction" rule of a gravity power collector.  Hi Tim!  Your  entry on this forum is a fresh and intuitive one.Thank you about informations regarding  Aldo Costa:"c'est formidable!".In my opinion,his enterprise is the best one ever made by a man.What a pitty that his "first imago" was an unbalanced wheel..so I figure.Now,a small comment ,face to some of your judgments. You said at Principle 4/Effects of scaling up/..."if you make the wheel bigger and keeps the weights the same size and moving the same distance out but and add more of them,you increase the potential energy or torque in the wheel"..."This is the real key that makes it work".In  my opinion,that's enough to think,imagine a greater arm(R),nothing more.The interdiction  "mgh" can become a dilemma(waiting a proof...mathematical or better,practical).Long time ago ,I said that gravity is as a lake(statics):no way for a self turning "wheel".I asked myself:and if the radius(R) is bigger and bigger,for the same up(inthe top and bottom positions) amount(h)  on that?After a long time,with this lack of clarity and amazement,in the same time,I realized that gravity is not a quiet "lake", only.It's more:a huge  potential flow(dynamics).So statics and dynamics.That is for I am here,when I read your "if you make the wheel bigger"..:like the story with a blind one-eyed man in a certain country,maybe.You said at Principle 2/..."so by increasing the number of weights around the wheel you can infinitely increase the amount of torque".Really,but in this way you will stiff,temper the free fall as in a weighting machine:a slight up and down motion about the horizontal line,only.Dynamics "submerged' into statics...I suggest you to try to imagine,in the beggining, a "wheel" with two spokes only.And let the mass fall,as you said   on a bigger and bigger arm(R) with the same difference long arm-short arm(h).You mind is clear,as you said:"if you try to harness a natural phenomenon it has to be in a fairly simple manner(...like fan blades to wind...)".So,I  hope you success!All the Bests!/Alex

Hi Tim!   Ok! The problem of long arm-short arm switch:try a repetitive  mass  rolling fall(it's self,due to gravity),instead of lift(is  "assisted").Take a look ,for your own solution(I wish you to be a best one ,than mine), at "Gravity  wheel concept" on the same "Gravity powered wheels".In my web site(New!New Drafts!) you will find out some drawings,designs.The "knotty point" is that my "decoding" of the wheel is a different one(at "Wheel vs. lever",in the same areal). Best Regards!/Alex

@nwman - I have been working hard on this wheel question and on making it turn with a simply process, without magnets or other fancy help. I worked until 4 am last night (my son was sleeping in front of Future Shop to pick up a Nintendo Wii which he got) so I had to stay awake anyways. I came up with the following design which I think will do the job. As shown on the drawing, the left balls are always no further then the stem, while the right balls are always sent futher out then the stem. This is a rolling ball design with a four sided wire channel providing minimal drag. The channel is designed to send the ball to the right and this can also be extended. The channel also has a left and right of channel that sends the ball to the other side before it gets to the maximum regular position to do so by simple gravity. Sort of a premature nudge. If you ask me, this wheel will turn indefinitely. I wonder if you can do some of your calculations to see if it holds true before I go into a prototype. The ball could be a metal ball, a billiard ball or maybe even a golf ball (but stay away from ping-pong balls). I think this design could be used in other fashions also for other mechanisms. Sorry for jagged edges of the drawing as it does not like the slanted rastor lines when transforming into a gif.

@Wattsup

It looks like you put a lot of thought in the that. I haven't seen one exactly like that but I have seen some that are close. I briefly mentioned somewhere earlier that i believe the weight has to travel straight out the spoke and not change its center of rotation. My having the weights roll out  off the spoke you run into problems. The way you have the wheel in the picture is correctly overbalanced but with a 30* rotation the wheel is over balanced on the other side as shown in the pictures. If you Google gravity wheels, perpetual motion, balls or marbles or some combination you will run into some simular designs. That is why I never fallowed that path because it looked like that had been tried before and failed. I could be wrong.

I came up with something this morning at work that might just work well for lifting the weights up. I'm going to take some more time and draw it up and think about it before I post it.

@Iacob alex
I'll take a look!

hi tim,
that looks nice,
looks like it would works.

ps: btw my idea is here (just to share)
