A floating territory made of a semi-rigid floating structure. The structure is able to follow the upward and downward movement of the waves. It can be installed as well close to the shores as in high sea, carrying a rigid structure. Said rigid structure acts like a bridge between the waves and provides a substantially stable surface for the installation of structures for human activity. Said rigid structure remains above the water level. The floating territory can be stabilized in position dynamically by propellers compensating the movement of the streams and/or winds, or by submersed weights attached to said rigid structure, or by pillars planted in the ground attached to said rigid structure. This leaves a vertical freedom of movement to follow the movement of the waves or the tides.

UNIV MICHIGAN TECH [US]

Absstract of: US2022252039A1

A nonlinear control design technique capitalizes on a wave energy converter comprising a shaped buoy having a variable geometry wave energy. For example, the shaped buoy can have an hourglass (HG) geometry having a variable cone or steepness angle. The HG buoy is assumed to operate in the heave motion of the wave. The unique interaction between the HG buoy and the wave creates a nonlinear cubic storage effect that produces actual energy storage or reactive power during operation. A multi-frequency Bretschneider spectrum wave excitation input was simulated for the HG design both with constant and varying steepness angle profiles which demonstrated further increased power generation with changing sea states for the variable design.
