Thats the point: you need
at least as much energy as needed to overcome to surrounding pressure and to enhance the volume.
Thats the whole point of my mechanical box: to make it easier to calculate this needed energy.
The surrounding pressure at the bottom, the buoyance and the falling distance are directly related to each other.

The pressure at groundlevel is directly depending on the density of the atmosphere and the gravitional pull.
pressure = height * density_ath * g
energy_gain = energy_gain_up + energy_gain_down
energy_gain_down = height * g * volume_sinking * density_ath
energy_gain_up = height * g * volume_floating * density_ath
energy_loss = pressure * (volume_floating - volume_sinking)
total_energy = energy_gain - energy_loss
As you can see the total amount of energy can be calculated by this simple formula which is only referring to the basic parameters of your system:
= (height * g * volume_sinking * density_ath) +
(height * g * volume_floating * density_ath) -
(height * density_ath * g * [volume_floating - volume_sinking])
since "height * g * density_ath" is always the same constant factor k, we can write:
= ( k * volume_sinking ) + ( k * volume_floating ) - ( k * [volume_floating - volume_sinking])
I hope it is clear this formula will always result in 0 !
It doesn't matter how big or small this factor of k is!
You can cange the density of the atmosphere, the gravitational pull and the height of your tower in ANY COMBINATION, it will only result in some different constant factor "k".
