: Just read Mr Tim's response - why do you think it would catch fire by rotating at 50 RPM? That doesn't make sense.
> Of course it doesn't! I was being facetious. - MrTim
: : On correcting my last true,true post. What it of course comes down to is, and I can see you feel the same way, by using a heat type mechanism within the wheel, one could gather heat from the enviroment, or one could gather heat from the wheel itself (axel-whatever) but it comes down to essentially dumping that heat so the process can continue.
> A Stirling cycle engine would be more efficient, at least as far as taking heat from the environment. Gather heat from the wheel? That implies friction, which generates heat. (They used to bore gun barrels back then, using a slow drill. The barrel got extremely hot during the process. Hmmm, we're back at the point of the wheel catching fire again...!)
: :Which was my point in stating that maybe that's the reason his demonstrated wheel was 12 feet in diameter. Suppose area (the outer perimeter) was what was needed to establish this. He could have a gas gain a little heat from the axel, work upon a piston, and then that piston flip to the outer edge to completely cool it.
: : ??
> That's fine for the large wheels, but still doesn't explain the 3 foot wheel. And again, since the innards were covered, wouldn't this trap heat? And why didn't any witnesses describe heat radiating from any of the wheels? Especially the Kassel wheel, which, after running for almost 2 months, would certainly have built up enough heat to be noticable? Strange that nobody mentioned it....
Forgive me for being skeptical of the gas/hydraulic/piston/(whatever) idea, I sincerely wish you the best of luck with it, but I see easier, more efficient, ways to overbalance a wheel, and that's where I'm putting my efforts and resources into.
