Yet another gizmo by Directory:Scott F. Hall, the University Art teacher. On August 6, 2007, after reading up on Bessler's gravity wheel and other designs, he quickly slapped a few things together and came up with what appeared to be a working device.

He sets the wheel on the ground and it appears to roll forward via the simple mechanism he's contrived, using the principles he gathered from his reading.

However, an OS:Hall Gravity Wheel B:Replica:Doug Furr of OS:Scott F. Hall:Gravity Motor B he built the next day, suggests that there is a gradual incline on his garage floor, which accounts for the rolling motion, rather than it coming from harvesting static gravity.

Level on Scott's garage floor suggests that it is flat, but such gauges are not accurate enough to show the slight incline typical for a garage.

Objective : The purpose of this PESWiki page was to report on this phenomenon and to encourage validation, characterized, then implemented into a practical application.

Conclusion : Scott appears to have an incline in his floor, which accounts for the motion observed. This gizmo probably would not work on a level surface.

Comments by Scott Hall

"This one is entirely my own design. I made it after reading conjecture on Bessler and Somerset designs and I decided the whole-wheel approach would be interesting to try." (Aug. 9, 2007)

"That is a flat surface." (Aug. 9, 2007)

"I've had no luck with center axle designs--only these whole-rolling-wheels work for me. If you look at another video of mine called "Bessler ?...", you can see propped against my car tire the 21" width remains of my failed attempt at doing an Edward Somerset style wheel--it formerly had 15 heavy lead weights tied by two cords within each of those "windows". It wouldn't turn long. For now due to frustration, I'm not doing center axle gravity wheels." (Aug. 9, 2007)

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.

: "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."

How it Works

On Aug. 7, 2007, Scott wrote:

: "I was reading interesting online sources about Johann Bessler and Edward Somerset (a.k.a. the Marquis of Worcester) and it seemed to me that their perpetual motion wheels probably relied upon 1) keeping friction down, 2) keeping a bunch of weights off-axis and 3) keeping more weights on one side than on the other.

: "So yesterday, I designed and built this crude gravity wheel from three glued laminations of ¾" plywood, nails for 8 individual axles, several ounces of fishing weights, and clear silicone seal to hold the weights into the 8 drilled-out recesses.

: "When I set this wheel with its 90 degree pivoting weights down, off it rolls! Yeah, it hobbles a little--it was just roughed out with a handheld jigsaw and drill.

: "I wonder why so many people just assume that self-turning wheels are impossible without first trying to build one?"


none (his posting this at YouTube prevents it Internationally, either by himself or anyone else)

Directory: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 B

Scott's first gravity motor, designed the day before the above design, also rolls forward when placed on flat ground via the simple mechanism he's constructed.
