Bi-directional turbines

Definition

Bi-directional turbines are specialized devices designed to generate energy from water currents flowing in both directions, such as those found in tidal and wave environments. These turbines optimize energy capture by allowing for power generation regardless of the water flow direction, making them particularly useful in applications like tidal fences and lagoons. Their unique design enhances efficiency and harnesses the kinetic energy of moving water during both flood and ebb tides.
