re: Frettsy's "Volatility Wheel"
Indeed! I had not seen the Minto wheel, although I had considered the similarity between my idea and the drinking bird. My idea is like an inverse of the Minto wheel, almost :)

Frettsy's "Volatility Wheel"
Hi folks, Long time no see (like, 5.5 yrs)! Nonetheless, I'm back. I've had this idea for a Volatility Wheel for a while. It's pretty simple/rudimentary, but seems certain to work. Take a wheel with, say, 4 spokes (but the more the better). On the end of each spoke, attach a compartment filled with ...

hi all - sorry I haven't replied in weeks - I've been away. I remember when I was little and one of the doors in my house would mysteriously open itself. I could have sworn it was a ghost. later I realized that it was air pressure - when another door at the end of the hall was opened, it would suck ...

thanks guys, glad you at least see potential here. KAS: since the air first travels perpendicular to the fall of the flap, then in the same direction (but on the other side of the wheel) wouldn't their energies sum together instead of canceling? it seems to me that this is a different case since the...

description of attachment (NOTE: not to scale!): think of the green compartment as a "shaft". the red flaps are on hinges so that they can move 90 degrees. at the shown state, the flap on the right is about to fall. when it does, it forces air (gray arrow) into the shaft. this air moves th...

how to make a lighter weight lift a heavier weight
I refer to my thread "path of least resistance (waterwheels revisited)" - specifically the part about the oil being "forced upward through the hose". now, my attachment. imagine the red plunger as weighing 50 pounds. below it sits 100 pounds of a fluid. the plunger is pushing dow...

couldn't find anything else about this here, but I think this could definitely be relevant somehow. thoughts?

here is another (very simplified) variation of the solar water wheel, Jim: make something like the standard MT1 wheel, with 8 compartments. make them watertight, fill each one with the same amount of water. put your left half in the sun and the right half in the shade. watch it go! or. space apart t...

interesting. so the 3:15-ball near the rim and the 8:45-ball near the axle are exhibiting the same downforce since they are below 3 and 9? I'm not sure I understand! I agree that the 3 above and the 1 at bottom cannot do any work. I think the next two from the bottom are offsetting. but the other tw...

variations on MT 1
here I have drawn a new design over MT 1, please disregard the original spokes and balls as I used them only as a guide for the new design. the blue and red "boards" and the purple "weights" comprise the wheel. the idea is to make the ball roll to the right higher on the downside...

Re: re: the weights hit the wheel
broli : btw, thanks for bringing the MT drawings here. I had not seen them before but now I'm checking them out on the wiki. both of these seem very workable and efficient. MT 48: "an insufficient number of spheres is carried to the wheel A by means of the paternoster"... but why? it seem...

WM2D or Pintar VirtuaLAB Mechanics
does anyone know where I can download a free version of either of these programs?
the free version of Pintar VirtuaLAB Mechanics is not available on their website anymore but I can't afford the full version.
I can't afford WM2D either and the demo is very restrictive!
