Just wanted share this great site I found. Lots of interesting stuff there.

Scott...
I inputted the words "perpetual motion machine" into the site's Search engine and got back:

Inputting "Johann Bessler" produced the same message...Your search perpetual motion machine did not match any documents

On 7/6/06, I found, in any overbalanced gravity wheel with rotation rate, ω, axle to CG distance d, and CG dip angle φ, the average vertical velocity of its drive weights is downward and given by:
Vaver = -2(√2)πdωcosφ
Vaver = -2(√2)πdωcosφ
re: KMODDL
great link, Scott, I do believe I will be spending some time with this one. Lots of thinking cap power here, Thank you for sharing.

Ken,
I'm not sure what you are trying to say. Is that a surprise to you for some reason? Maybe try searching for "wheel," "gravity," or "stork bill."
Ralph,
You're welcome, have fun.

Actually, it is a bit of a surprise to me. I looked through many of the collection of 19th century mechanisms and models and there's nothing there that even mentions perpetual motion devices. Yet, the quest for mechanical perpetual motion was, oddly enough, perhaps the main driving force behind the development of the engineering sciences for the last half a millenium! One would think that will all of the various PPM designs developed over the centuries, there would be at least one of them mentioned and its mechanism illustrated on the site. But, there's nothing.
Maybe they figure if they pretend these devices never existed, then that will somehow suppress mankind's quest to attain this age old dream of self-moving devices...
But, thanks for posting the link anyway.

Scott,
Thanks for the link. I'm finding it very useful for ideas in working out some mechanical issues in the wheel shifter mechanism I'm building.
I too will be spending some time on that website.
Really appreciate it!!!
Preston.

re: KMODDL
Thanks for the link Scott. Lots of interesting toys in there. Something in there might spark the idea that we are all looking for. Since they are illustrating known mechanisms it is hardly surprising they were unable to show Bessler's device that has been lost to the world for nearly 300 years.

Hey Guys,
There is a copy of Leonardo's Codex Madrid out there!

re: KMODDL
Well, this is actually the third time this site has been mentioned now, I came across it back in 2004......
A clue from Bessler?
I guess it got buried in community buzz.
