Step-by-Step:

Descent Phase: In a typical plant the pistons descend 3.05 m, pressurizing water to a 1,495 m head, generating power (e.g., 10 MW per Slim Cell set).

Ascent Phase: Buoyancy lifts pistons back up, powered by feedback energy (0.5 MW per set).

Synchronization: Alternating pistons with a 7.5 s overlap ensure uninterrupted output.
