: : There are one or two things about this wheel of yours that don't add up.
: : Firstly the wheel seems to be uni-directional, if this is so then why the need to give it a push? surely it should start without any human intervention, as a matter of fact surely the only way to stop such a wheel would be to physically restrain it with some kind of brake (like Bessler's uni-directional wheels)
: For the most part I agree with you, however, it is possible to build a "pulsed" wheel that would exhibit, say, 40% negative torque and 60% positive torque every 45 degrees, for a sum total of 20% OU and therefore continuous rotation, but it wouldn't self start if it happened to be sitting in a torque trough.
I feel a wheel can be made that is only O/U at high speeds
as well, perhaps using 'pumped' centrifugal force...untested,
as yet...I am also wondering if a wheel is even needed at all;
all 'neat bits' not IN the wheel.
: : Secondly I would like to ask a question that quite a few have been asking and you don't seem to be answering - how long does the wheel rotate for when set in motion? a few minutes? hours? days? indefinately? please tell us as this information is important.
: According to a message VITW posted on that other forum site, "The device's speed is self governing, it ramps up to speed quickly and simply stays there"
I'd love to see a wheel accelerate untill it destroys itself-
(unless it was mine) now that's O/U!
: : In all honesty I do not think that you have a gravity powered wheel I think that you have a flywheel. This is evidenced by the fact that the wheel has to be set in motion with a push and does not self start (as it would if it were a gravity wheel) I strongly suspect that it will not sustain it's own rotation and stops after a few minutes. Those lead weights probably add to the fly wheel effect and keep it in motion for a good few minutes.
: I agree with you, but not because of the reasons you cite, because of the fact that this wheel is one of those designs that *looks* like it should work but it has alot of hidden math magic going on. For instance, see Desagliers proof that weights affect a wheel at the attachment points based on orientation, not simply the weights physical (or visual) position in the wheel.
Yes-cool...'virtual weights' I call them-not real weights,
but a center of gravity between 2 weights-that's where the
wheel 'sees' the weight act...an important technique,since
it seems to also kill off most if not all of the inertial forces
of moving weights too... :*)
Also, a weight falling on an arm attached to a wheel 'unloads'
the wheel while falling (accelerating down) and feels
heavier accelerating up...static tests are useless...
: : I would probably have to re-evaluate the above if you tell me that it rotates indefinately and accelerates after a small push! I would probably have to replicate it as well!
: That's exactly what he has come right out and said. I think some outside verification is in order.
Well, that IS what we are shooting for...
