Mathematical Analysis of an Ideal ZED

[mondrasek]

    That was crap mrwayne,
                 Archimedes himself reckons that it is the the volume of the immersed part of the object
    which is important, NOT THE DISPLACED VOLUME.
        Try again, better luck next time!

Volume of the immersed part vs. the displace volume:  Are they not one and the same?  I guess I am not following what you meant.

            The displaced volume is the volume of say water, which the object itself displaces.
    This can be much less than the immersed volume of the object.
        The energy requirement would be inline with any work done lifting the object itself.

Sorry John, but that is incorrect.  The volume of any object immersed in water will displace an equal volume of water.

Now the WIEGHT (Mass) of the two can be very different.

But the volume is the same.  That is Archimedes' Principle.

The ZED has more buoyancy than its total displacement

And below is why. The only pure Archimedes shown is the Pod. The Risers are hydraulic pneumatic hybrids using only the accumulated head pressure of the water heads in the surrounding circles.

  Mond,
          OK. I give in.
         I was just following the Koala and his virtual water.
