Big try at gravity wheel

    Sunset,
               dunno about the production line, sounds as if he's moving in to a Portacabin

Porta is good, but Cabin is not the way to go. The money is in Potti.

Webby the video demonstrates the 2000 year old Archimedes' Principal that it takes an identical displaced volume of water to produce the same amount of buoyant force.  The set-up on the left displaces with a combination of a cement insert and surrounding air.  The set-up on the right relies entirely on air to displace water.  In both cases, the air transmits the force of the displaced water to the underside of the cups.  The focus that Tom Miller places on the air is entirely misdirection.

MarkE,

If you go back to post of 1+ week ago, it was said that the video only demonstrates the 2000+ year old Archimedes principle paradox , straight up and inverted.  Nothing new here, the only bonus is the most optimum fluid volume quantity that needs to be managed.  You are correct about the stroke displacement volume requirement will equal equivalent energy input.
It is beneficial to see the water column and displacement as 2 separate entities.  Water column is force and its volume is of a setup nature and a loss factor and the displacement volume is of a dynamic nature and equals energy. In essence, the paradox keeps the loss factor to a minimum,  but you still need to pay the piper.

What Wayne did is to integrate the displacement quantities for the outer surfaces in the water column pre-provisioining  and  with this setup shares the displacement cost although that doesn't come for free, he pays for it in pressure increase which evens the score.  The displacement sharing and  pre-provisioning principle therefore do not gain you anything  beyond an efficiency improvement.
What is does do is to give you the possibility to control you lift,  by pressure control you can determine at what ratio the lift takes place, bi-directionally. in a non-linear fashion.  Because of the bi-directional property, the need for a dual setup is without doubt the best solution to handle this energy exchange and the rest is history

     Yes,the rest is history..........and then nothing happens!

    Hi,
       would anyone agree with this statement?  If you have identical cyliners you have to more
   than 1 on your initial stroke.

If you make too many idealizations you lose contact with reality and can wind up "proving" all kinds of non-physical things. For example, many of my constructions would run "forever".... if I could only neglect bearing friction, air resistance, eddy current drag, and the influence of gay pixies on my herd of pink unicorns, etc.
