I see what you mean, but what if somehow the wheel benefited from this centrifugal force ?
I have until recently viewed the centrifugal force as destructive for gravity-power, but recently I found that if speed is altered when lifting / lowering, because energy is transferred back / forth between springs, one can harness gravity based on its conservative function !

Something like MT 17 (not that I plan to use the MT 17 principle, but just have a way to show what I mean :-)
where the weights first move very slow, then accelerated nearer the top, and follow the rim on the way down.
If you calculate the masses centrifugal force in that picture,
you see one way how centrifugal force can be altered, when another principle is used where the masses are !
Then centrifugal forces can be removed when lifting....
Example :weights are forced out towards the rim as they fall, compressing a spring.
When lifted, the weights will resist lifting and strech another spring, that means that the weights loose their velocity.
When they loose their velocity, the centrifugal forces are reduced, and the compressed spring will push the weights towards center, and the lift will be easier....

Ehhh, if that was somehow understandable ?

How is your book project going by the way ?

: Hi Oystein,

: Centrifugal force applied to free-to-move-weights within the wheel suggests huge mechanical difficulties when calculated for the uni-directional Draschwitz wheel.

: This wheel was reported as rotating at 50 RPM and was 9.13 feet diameter. At this speed centrifugal force applied to a weight at the rim is much greater than 1G. IMO, this raises some pretty serious problems for any system that utilises a purely radial movement of the weights.

: At full wheel speed (Draschwitz wheel) it would seem that a weight rotating with the rim would need a crowbar to lever it directly back in towards the axle.

: Regards, Bill.

: : Hello again :-)


: : For the ones int. I thought I should "bable" a bit about how besslers wheel was related to centrifugal forces mathematically !


: : In his biggest wheel we can calculate how big the centrifugal forces wore, and from that see if they somehow could be a major factor, an maybe we can find a "lucky" relation !


: : Lets see at what RPM the centrifugal forces will be equal to gravity !


: : RPM(Fg = Fc) = (g * r)^1/2 * (60 / pi*2r)

: : g = 9,8

: : r = 1,825


: : Resault = 22,1 RPM !


: : At this RPM the weights are "weightless" at the top and

: : have F = 2g at the bottom.

: : We know this wheel rotated at about 24 RPM unloaded and about 20 RPM loaded.


: : :-)
