OS:Scott F. Hall:Old Indian Gravity Wheel
Yet another gizmo by Scott F. Hall, the University Art teacher.
This gravity wheel, first announced on Aug. 28, 2007, is composed of metal balls inside slants within wood, which apparently keep the wheel off-balance, resulting in rotation on its axle. He says the rotation speed fluctuates up and down, as the motion switches back and forth from kinetic to overbalance.
- The purpose of this PESWiki page is to report on this phenomenon and to encourage validation, characterization, then implementation into a practical application.
- Validation Status
- Not yet validated.
- "The design was first shown on the second Chas Campbell video a few weeks ago and is NOT some ancient Indian design. It does not turn by itself." (See comments)
We offer this page as a collection of information about this wheel.

This new wheel will have 8 tilted channels on each side--16 total. In each channel will be an equal number of ball weights (the old stories from India suggest mercury be used instead). The weights shift freely as the wheel rolls. This shifting-in-channels action causes the edge weight of the wheel to be constantly located well over to the right of the center axis--this should put the wheel constantly out-of-balance and make it want to keep rolling toward that bias. The middle region of wood has been cut out in order to reduce weight in that inactive zone of the wheel but clear plastic will remain in that area--it's not heavy.

Here's my finished ancient Indian-style gravity wheel. It's made with transparent surfaces to allow a view in on both sides. Also, these sides present only two very thin edges to the floor if/when rolled on the floor. That creates less friction, I guess. Sorry about the dark paint—I meant well but it mostly just enhances glare now that I look at it here.
One of you asked me to try out one of my wheels on an axle—easy to do with this wheel by simply inserting a half inch oak dowel right through holes drilled through the middle of the plastic sheets.
This wheel works quite well as an old fashioned overbalancer but the action is odd. It first cycles the ball weights over and over at a medium r.p.m. rate but then it picks up speed and starts going faster like a solid state flywheel. Later, it slows down again to medium r.p.m. with balls dumping slower and then it accelerates again and runs like a flywheel. And so on.
I'll respond here to a couple of statements about me I see in blogs. Yes, I am shooting with my digital still camera—there's not much memory in it, so 21 seconds is what I get. And no, I'm not just a college professor with too much time on my hands. I get paid to teach, to serve, and to do research. Everything I create qualifies as research (i.e. making art, exhibiting art).
Feel free to let us know about any replications. You can edit this site.
Similar Model Didn't Work
Comment submitted on Sept. 5, 2007
It is my personal opinion that Scott Hall is toying with you. You already caught him in a fraudulent claim on the first two "gravity" motors, and I am surprised you would give him anymore press. Years ago, I built a model similar to his current design. It doesn't work. That one slows down faster than a normal flywheel. His film has the same problems as the Perendev film, that is, not showing the back side of the system where he obviously has a drive motor! I can assure you that in that design, the "center of gravity" stays on the side that retards rotation.

Other Gravity Motors by Scott Hall
The rolling motion of these two wheels was apparently due to a slight incline in his garage floor surface.

Gravity Wheel B
- 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 by a simple mechanism; but is probably due to slight incline in floor.. ('YouTube)
- Chas Campbell - Clean Free Power - Video produced by Chas Campbell shows large gravity wheel turning, as an alleged input energy source for his generator system and all the appliances it powers simultanously. (YouTube; August 10, 2007)
- Chas Campbell Generator > Chas Campbell Generator Discredited - It turns out that the Australian inventor who made Channel 10 News in July, demonstrating an alleged overunity generator with input of 800 Watts, running 3500 W output, operating a drill, a saw, and other appliances; was apparently doing so via a flywheel effect, not because of harnessing some free energy source.
