A screen shot of the YouTube video Scott posted demonstrating this second gravity motor design he build.

Yet another gizmo by Scott F. Hall, who teaches Art at the University of Central Florida.

This one, built on August 8, 2007, is a replica of YouTube user paddyboytube's design; and is Scott's second seemingly working gravity motor design in two days. (See the first one.)

In his video, he sets this wheel gizmo on the ground and it gradually accelerates forward.

In a subsequent video, Scott shows a level that indicates his garage floor is flat. [1]

In the next scene, he shows his two gravity wheels in a heap on fire, and his comment text says he couldn't put up with all the skeptical comments.

A subsequent replication of this design by our mechanical engineer shows that it does not accelerate or maintain its speed across a flat surface, but decelerates as present laws of physics would predict. This device does not run on static gravity.

Objective 
We posted this PESWiki to report on this phenomenon and to encourage validation, characterization, improvement, and implementation of the design into practical applications.
Conclusion
We have defintatively show that this design does not work as claimed.

  • Bessler ? Gravity Wheel Perpetual Motion Machine - the title chosen by Scott when he posted this at YouTube on August 08, 2007. Device appears to roll on its own via a simple mechanism. ('YouTube)

Comments by Scott Hall

"The floor of my garage is utterly flat." (Aug. 9, 2007) [2]

Q. is it self sustaning?

A. 
"I'm not sure yet. It's only rolled so far in there before hitting obstructions or reaching the point at which the concrete really does slope (outside the garage). It's pretty crude--friction probably does catch up with it in time." (Aug. 9, 2007) [3]

Prototype Burned

  • Gravity Wheel Perpetual Motion: Accelerated Entropy - title chosen by Scott in his video post at YouTube.

On Aug. 9, 2007, Scott posted the following comment along with a video showing a level on his garage floor that proves his floor is flat, followed by a view of at least three of his gizmos burning in a heap: Gravity Motor A, B, and his Electrostatic Generator. [4]

"Everyone: Thanks to all who've supported my work, but I do have an artistic temperament: so many destructive comments and so darned much spam has driven me crazy! GOODBYE, clunky prototypes. If/when my patience returns, I'll probably build a wheel that's larger, one that's not crude, and one that is critically bulletproof. Until then, good luck to those of you who possess the positive spirit required to continue this work.
"The floor is flat."

Scott's Account of Constructing this Device

On Aug. 8, 2007, Scott wrote: [5]

"I watched the youtube videos Bessler1 and Bessler 2 [May 15, 2007] and, despite the negative comments left there, I thought paddyboytube's design was intriguing in its simplicity of interior click-clacking weights.
"I took 15 minutes to build one and here is the result in video. It looks pretty efficient in resisting friction and it makes a pleasant, uniform noise as it moves, too. I'll have to try making one of these on a very large scale with many more of these log weights spanned through the center.

Principles of Construction

  • Round "wheels"
  • Horizontal Dowels
    • 120 degree placement, of the three dowels symmetrically around the circumference
    • For optimal performance, dowel insertion around circumference needs to be as close to the edge as possible while allowing pivot of the perpendicular dowel without the perpendicular dowel hitting the ground.
  • Perpendicular Dowels
    • Perpendicular dowels are all the same length
    • Perpendicular dowels are all of the same weight and circumference
    • Perpendicular dowels do not have to be round, but do need to be oriented on the horizontal dowel the same way as one another if they are not round.
    • If not round, the perpendicular dowels need to hit the two other dowels (120-degree placement) with the same amount of displacement on both sides as they swing back and forth.
  • Friction of the perpendicular dowel swinging around the horizontal dowel should be minimized.
  • Optionally, the perpendicular dowels should be kept from moving left and right into one another by some restraining mechanism that does not introduce too much resistance to the free pivoting/swinging on the horizontal dowel.

Patents

none (the posting of this design at YouTube prevents Patenting it Internationally, by anyone)

Suggested Procedures

When you make a replica, we suggest some of the following methods to help make your presentation more believable.

  • In the same take, without stopping (e.g. have music playing in the live background), roll the device one direction, then the opposite direction.
  • Let it roll long enough to reach its steady-state speed.
  • Have a control object next to it, and give the control a little push to see that it decelerates while the Gravity wheel accelerates then reaches a steady-state speed.
  • Experiment to see what rise in elevation the wheel can climb, given a little push to start it.

Coverage

  • Gravity Motors > Johannes Bessler Rehabilitated - While the history of overbalancing gravity wheels is spotty, the Bessler Wheel apparently worked well but went to the grave with its inventor. Now the concept seems to have been replicated in two different devices by Scott F. Hall. (Hasslberger Blog; Aug 9, 2007)

Old Indian Gravity Wheel

  • Finished Indian Perpetual Motion Gravity Wheel - the title chosen by Scott when he posted this at YouTube on Sept. 1, 2007. The video shows wheel axle held by hand, as the wheel apparently accellerates. (YouTube)

See OS:Scott F. Hall:Old Indian Gravity Wheel - Bearings in slanted shafts appear to make the wheel continually off balance.

Gravity Motor A

Scott's first gravity motor, designed the day before the above design. He sets the wheel on the ground and it rolls forward via the simple mechanism he's constructed.
