@ All

 Here are some pictures of my table top wheel stand. It IMO would be a good stand for those who don't have much room but would like to build. I use angle iron and welded tabs for bolt to tighten the bearings in. They sit well in any V shape without having to know the proper size. Then I welded it to 1 inch square tubing. I use mine for quick ideas and test. The closeup shows the spacing or two bearings to keep a stable hold on you axle. In my case it is 1/4 all thread but I think I am going to up it to 3/8 size. This way I can use 18 inch disk.

Greetings Bill

 That is a very good suggestion. Thanks! I have a couple of them in my surplus but when I did some pricing some of them where high cost. Do you know where we could find them at a reasonable cost?

 I guess that the removing of the grease is the cheep way. I get most of my bearings for less than 3 dollars each. and if I find some rollerskates at a yard sell. I can get several for a lot less. But when it comes to build the next wheel after the test wheel. It will be well worth the cost of the ceramic bearings.

Thanks again Bill

Alan

edited rollerskating. Well I kind of miss rollerskating  :'(

Actually, I don't.  We used to make our own.  Of course, I owned a precision ceramic machining corporation all equipt with diamond tooling.  We used to make them for NASA and General Motors and others as well.  I have no idea who is making them now and for how much.

yes good thread indeed gravity wheels are very time consuming as you say all those builds and you have prospects I just hope folks know what they are getting into they can be very disappointing to build it will take many failures to find a runner that I am sure of as proven through history...

My question is this why not make a design that is capable of brute force somehow... The ability to keep using the same wheel over and over with different applications of gravity power would be great!

 The reason for removal of the A in the bearings is for the test wheels. This way if you finds continuous action you will be able to build up from there. In a small test wheel this will allow a more positive understanding of what you are doing, and not a misunderstanding thinking you may not have a non runner due to stiff bearings. When you build the larger wheels this is not as much a problem.  ;)

Alan

PS I like wheels that can overcome allot of friction and have plenty of energy over that as well.  ;D
Ok I see :)

Agreed. It seams it takes forever.... I think however we need to get some help from Mother Nature. Harness the energy potential that is already there, and combine it with a gravity wheel. Because it is hard to understand that a wheel can power itself with no help.

Hi Vidar

 Gravity is all we need. But you have to figure out the reactions of the device that the Gravity activates is the trick.

The problem is that the gravity works equally on both sides of a wheel. Without help to distribute energy, the wheel cannot run.
I see however the need to understand the mechanism. The closer you are to understand the mechanisms, the farther from a self sustaining wheel you understand you are.

Hi Vidar

Lets look at this. Which is gravity pulling harder on? An object going with gravity or an object going away? In a wheel you have both effects despite the constant pull of gravity. It is easier to fall, than to jump up. Now you do have a difference to consider, and you have to understand how to capitalize on this information.  ;)

Well, it is easier to fall if you already have been carried upwards by some one else. If you had to climb up to that altitude yourself, the fall will just compensate for the energy you used to climb up. And where did you get that free fall in the first place?

OK. Imagine this. One single weight is taking one round on a wheel. Its path is circular, or maybe not - doesn't matter. Its velocity is constant, or maybe not - doesn't matter. The weights is changing altitude of 1 meter from the very bottom to the very top.
What part of gravity is letting this weight to take one more round, and keep that forever?
What if we add more weights so the lonely weight can have some company. Will then the weights have a better reason to keep spinning around in that loop?
It is all about kinetic and potential energy. About where the weight is present in altitude at any time. About the velocity of the weights at any time. No matter which path these weights are taking, all that matters is the altitude position and the velocity of the weights at all times. The sum of 1 meter up minus 1 meter down is still zero - no matter how the path is on its way up vs the path on its way down.

There is in other words no excess free fall of the weights which is letting the gravity wheel keep spinning, because the physical limitations of the wheel isn't allowing them to do so.

It isn't more complicated than that :)

That is the reason why I took the gravity wheel a step forward. Using environmental temperatures to control the weights in order to have a true unbalanced gravity wheel. This is not new, however, but it should work.

 You mean like this test I posted on youtube 2 years ago?

http://www.youtube.com/watch?v=xhskB-0SjKI

Now for placement weights you are correct. But use the energy of the stronger resistance of the ascending weight to make the shift to improve the descending sides effectiveness to keep possible acceleration. As seen in the video the weight falls faster than it lifts but the extra kinetic weights allow for a more solid flywheel effect that helps lift the weight back over. Of course this was just a simple test and not a running wheel but the slowdown was hard to detect in the first minute of running. There are ways to do things if we keep an open mind to try. The quest is to find those ways.  ;)

Greetings All

 Some more good information, and a good tool to use, is on one of my older strings from 1 1/2 years ago. This help with understanding of how weight placement reacts on a wheel.

Well I feel that we understand each other, but we do not agree :) It really does not matter how weights are configured as long the difference between max and min. altitude is constant. Really - think about it. It is really not that complicated. We do not only know that gravity is conservative, but we also know that each and every attempt to make a working gravity wheel has failed. Shouldn't that be proof enough? Well, you might say "no".
We did not believe that planes could fly a few years ago, but should the planes start falling down from the sky the day we finally have a working gravity wheel? Because all the sudden the laws of physics did change! Planes don't keep flying because we don't know better :)
So be careful with that gravity wheel, because one day I might have an Airbus 380 in my living room ;D

@All,

Not sure if this has been posted before, it says 2007, but this patent caught my interest.

Gravitational magnetic energy converter
http://www.freepatentsonline.com/y2008/0174121.html

The idea of using a heavy mass combined with gravity to get past the sticky spot of the magnetic ramp needs investigating.
