Darrell Vandusen of Ontario has built a "gravity motor" 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.

none?

Stage of Development

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.

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."

Rotation of First Prototype

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.]

Darrel,
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.

>>Is this recent footage or archive footage?<<
The video is 4 years old today, way too long to still be looking for someone to replicate my Gravity Machine.

I would like nothing more then to have a contract with someone to replicate the machine; and hopefully they can also move it forward, onto the market.

>>Is the prototype available now to shoot new footage of?<<
The original is disassembled and the nine foot machine that was being built is also apart. The nine footer could be reassembled but would not show what is required.

>>If so, how about some longer footage showing several revolutions?<<
You may have read, I made some rules 4 years ago and one was never to show a full rotation.

I need a machine built with a breaking system, tachometer, and a generator to be hooked up. This machine will answer all questions.

To date, I have had one person stop funding and then had to move the machine.

I found a person to build a machine with all added equipment, then they stopped 1 1/2 years after they started, so they could concentrate on their own business.

Today I have the parts to assemble and no place to do so. All I can do is build a machine 4 feet in height, for that is all the room I have. All I need is funding.

If something changes, maybe I can have you video the next completed machine.

In the years since I finished the machine, I have thought of giving it away and then thought I should first guarantee an income for myself and my family. I put in 25 years and a fair amount of money into this machine. I cannot just give it away, I need something first.

The next person to build it, should first be able to understand the way it works, using my explanation, with regards to 30 degree resets, also videos and spreed sheets. Then I should only let them build their own machine, under some kind of contract or maybe under escrow.

I know showing [a full rotation] video is an easy way to fast forward this machine to market.

I am still trying to find a better way to convey my explanations for why this machine works and also how to get more then just the power requirements to operate itself.

A lot of my problems is my communication skills or the lack thereof; also engineering terminology.

My six foot wooden machine, proved the 30 degree movement, about 13 years ago.

The six foot machine of 4 years ago only ran for 2 or 3 minutes at a time at the most, and for only 10 or 12 RPM.

You must remember, there was no breaking system on the machine, and I had to keep it from moving too fast. I had bent a spoke and did not want anything else happening to the machine.

At that time I had thought the machine could run in the hundreds of rpm. I now believe a gravity machine will have to be keep under 50 or 60 RPM. I know this from the experiments on the nine foot machine. When the nine foot machine was spun, the clicking sound would disappear at about 60 rpm and start to reappear at around 43. CF is a real down fall for a gravity machine.

I never had anything hooked up to my machines [for a load]. (Unfortunately)

The six foot machine had about 110 inch/lbs of torque and only 8.5 inch/lbs left over at start up. The machine's power is divided into two needs. The first is to run the machine's internal requirements. Whatever is left can be used for a generator.

It is easy to double up on the power output, several times over.

In time, I will get something put together again.

I found this video to show you, for the following reasons.

First, this is not a working machine, as you can see.

It shows why I could not let it spin very fast, not even as fast as it is in this video.

When I was standing at the three o'clock location, I was keeping it slower then what it is in this video.

As you can see, this machine must be built with its intended RPM in mind.

This video gives an idea of what the machine looked like, the first time it ran.

You should have been their when the spoke was bent.
