Darrell Vandusen of Ontario has built a "Directory:Gravity Motors" or machine that he believes will harness gravity to provide output energy. Some of the photos are posted below video available under NDA, shows rotation.
Synopsis : There is no working prototype at present. The previous 6-foot diameter prototype rotated, but not well.
One 6-foot diameter machine was built, and allegedly functioned.
Another machine was built which was 8-feet in diameter, canabilized from the first, but it did not work.
A 9'4" device is presently being built using parts from the earlier devices.
Darrell said the earlier device starts on its own, and rotated. Stefan Hartman of OverUnity.com, who had signed a Non-disclosure agreement (NDA), says several videos he has seen corroborate this claim.

Second prototype 8-feet in diam. is in process of being built.
'' The following was posted by Darrell (July 06, 2006, 11:30:16 PM),
: "The photo is that of the bent spoke and it only shows the left side (1/3rd),of the photo. With regard to a picture of the machine, I have been looking for the correct one to post. This photo is part of the eight footer. It should show enough, to tell part of the work involved and the size."
On July 19, 2006, Darrell wrote the following by email:
In my estimates, the six foot machine only turned about 7 to 8 RPM.
This only happened for 2 to maybe 4 minutes. The reason behind such low RPM and the time the machine was allowed to rotate was when it first started, I had some problems with the inside and outside, lock and release systems.
The problem was mostly at the top, when the lock would not do it's job and the weights were not keep onto the outside end of its spoke. when this happened, the machine would just stop.
At one time, the bottom system did not release and the spoke was bent.
The reason I show the bent spoke is to show the power of this small machine and that it had only moved, either 60 or 90 degrees, when the spoke was bent. Remember this machine only has 4.5 lbs of torque, when at a stop.
Also, I was always at the 3 o'clock location, keeping it from moving to fast.
At one time I thought a machine would rotate over 980 RPM, I now know it must not go over 43 RPM or [centrifugal forces] will come into play.
This type of machine, can be built to just move, or built to have extra power output.
The machine that is now being replicated is 9 feet 4 inches in [diameter]. All that is left, in its completion is the top system and the fine turning.

: The video is of an old wooden machine. I built it about 14 years ago. I had no other way to build one, because I only had wood working tools. I then had to design a machine, with only wood in mind.
: That wooden machine never rotated, it only moved about 30-35 degrees. It proved some of the experements that I needed to scale up in order to use the many variables that are nessesary for a gravity-powered machine.
: This machine had about 144 lbs of moving weight and it was very, unstable. It did have a lift of 7 inches. This may not sound like much but you should know that when it moved, it moved 36 lbs, a total of 14 inches and three spokes at one time.
:The start up of the 30 degrees was good enought at the time.
: Speacking of start up, not many understand the importance of a machine that can start by itself.
: I now have a machine that resets itself every 30 degrees.

: I just had another conversation with Darrell via MSN messenger and after signing the NDA.
: He showed me a few videos where one can see the principle of the wheel and it is really a very interesting machine.
: The next videos he will send me will show the machine running for a few revolutions, so I would be sure, it is really working from gravity alone.

: [...] On the video I have seen from the 6th of January 2003 [Darrell] is standing at the wheel and selfstarts it and the wheel accelerates and gets faster! [...]
: Also the function principle is pretty clear to me and I always thought that this is the principle Bessler must have used.
: I have seen quite a bit of evidence now from all the videos Mr. Vandusen did send me.
: Sorry, that I can not post the videos, but I have signed an NDA.

: "In my video I have, you can see him going by the machine, releasing it and it starts by itself and begins to accelerate and you can see it for about 60 degrees turn."
[This contradicts the earlier statement by Stefan saying that the video is convincing. Such rotation could come from regional imbalance in the wheel.]

For over 30 years he has been trying to build a self running gravity wheel. He believes he can do it even today despite many failures. However, the reality is none of his devices are currently self running." (Revolution Green July 18, 2013)

: You sent out the same picture 1.5 years ago at http://besslerswheel.com
: Next he will show a video from a tv, were the VCR is plawing back words, and then he re-tapes the vido, so it looks like the wheel is picking up speed! Look for the 60 cycle flicker in the video.
: The guy is a FRAUD!
: He talked a member besslerswheel.com out of a bunch of money, a computer digetal camera, scanner, etc.
: ps. If you wont to see a picture of Darrel, just go to besslerswheel.com , and look under "FRAUD"....LOL
: pps. Darrell, Pete still wants his $10,000 back.

: The guy with the username Clarkie (Pete) on the besslerwheel.com forum did not cry, when he lost 10.000 US$ and he also never posted the real sub-conditions that were set up between him and Darrell. The only guys that cried are you and a few other guys from the besslerwheel forum. Why ? You were never involved''...??

This video will show you that the machine was built and it resets every 30 degrees.

The video is only a short clip. The original shows a weight at the 1:30 location, not being in its correct position on the outside of its circumference, so the machine does not start. When I put the weight were it belongs, the machine starts. You must remember that this machine only has 8.5 inch/lbs, more then the machine needs to start on its own. This is why it looks like a coaster.
