Segmented composite layers adjust radial stiffness to prevent stress concentration and separation, enhancing energy storage capacity.
Densely packed incompressible rocks counteract buoyancy and distribute hydrostatic pressure, eliminating complex hard shell construction costs.
A control section adjusts pumping input and power output to match set target values.
A gas pocket displaces water from submerged surfaces to prevent fouling, eliminating chemical anti-foulants that harm the environment.
