Buoyancy calculations – making use of an exception to Archimedes' principle?

[panyuming]

How do you seal the pontoons against the shield without creating massive friction?

The principle is the foundation, everyone determines that the principle is correct,
and then how to make the second layer.

It may be possible to use the nano fluff on the surface of the lotus leaf.

There are some situations that are correct but cannot be implemented, such as the space ladder.

@Panyuming, interesting design. Thanks for sharing. Maybe it fails based on below site case scenario which whould be applicable to H1 in your design (aand probably partially to H2 and H3). It looks like Fb not only changes direction but also increases?

I don't completely agree Willy. If you exclude water from the bottom of an upturned cup and place it on the bottom, it will stay there.

So ? A playing card will keep the water in a over turned cup as well.

Try it with something other than a cup.

Question. is a buoyant in water, 5 sided pyramid, changed in buoyancy when its point faces down ?  Of course not.

Note...
   Precision mated, ground glass surfaces are what is needed in the ferris wheel design.
  The viscosity of water is too great for water to leak through the plunger and barrel fit
  in my syringe.  Even so, the sliding action is very low friction.

I also don't think it's possible that simple to succeed.
