9. An energy island system arranged relative to a body of water with a seafloor, a water surface and a depth over an underground, the system comprising:
a structurally rigid shell extending from the seafloor to above the water surface, enclosing a lagoon of the body of water;
material with a negative buoyancy stacked around the shell forming a gravity stabilized wall;
a tunnel established in the wall, providing for hydraulic communication between a surrounding body of water and an interior of the shell;
the energy island system further comprising at least one of:
a shaft extending into the underground below the interior of the shell into a permeable substratum;
at least one branching tunnel, the branching tunnel being at least partially located in the permeable substratum, and in hydraulic communication with the shaft; and
a turbine/generator combination arranged in the shaft;
or
a shaft excavated in the underground below the lagoon into a salt deposit below an impermeable stratum; and
an input tube structure allowing water to pass from the body of water into the salt deposit establishing a cavity in the salt deposit.
