Wheel vs. lever...

...can make us think about a facile setting side by side.

   Any design that takes into account a wheel (many spokes) or a lever(two spokes only) concept is equivalent,with a fall in gravity that follows a circular,or curvilinear track...a particular inclined plane.

   The most noticeable characteristic of gravity fall (this  "invisible flow"...) is his nonlinear development with the  time  factor:  "g" is a constant acceleration,so we can get on this inclined plane, an ever increasing velocity (kinetic energy)...if...we let it fall rather more time

  In this situation,the lever concept seems to have a certain advantage....

  ...as a concept is on the line "why make it easy,when you can make it difficult?!"

     Or more matter,less art.

   ...concept , setting side by side,becomes essential ,when we take into consideration the measurable quantity of movement,that we can get out ,due to gravity fall.

            The hub and the spokes,usually are figured as a common,rigid body that can rotate  in a single manner: with a collective angular velocity.

            The hub,adds the effort of all spokes.

            The contribution of any spoke is variable,not only owing to the momentum's arm ,but especially due to their free fall velocity.

            Here is the point: in any sequence of the process,the spokes ask for some individual angular velocities.
 
            In this way,instead of  "an army of one" effort,we have  "a nonsense stampede" stess : at any time,some moments are pushing,some moments are pulling....and their possible summ working effort, becomes smaller.

            Here we have a "to be ,or not to be " problem : before to discard any  "wheel  concept" design(more than two spokes),give them the last chance,that  of two spokes only.

why wait for gravity when you can create it in revers, any amount. Centrifugal /centrepetal force is like gravity, only backwards/ inside out. with Cf, you can manipulate alot of variables that you cannot with gravity.

         Hi Cameron !

Your question up-there can get a multitude of answers...

My answer is this:if in the future we will be in a different planet(like Mars...),with no other flow(do you said rivers?),but gravity, we need to know how to take out power from this only source...
