How it Works

The constant energy from currents can be transformed into energy via turbines in the same way that the wind powers turbines. The kinetic energy of the moving water causes the blades of the turbine to rotate, causing the gearbox to turn with mechanical energy (Ahmed and Shoyama, 2011). The gearbox is connected to the generator, which produces a direct current, a form of electrical energy. This electricity is conveyed to shore via underwater cables and is then converted into an alternating current (used to power all electrical goods) and dispersed to consumers through the existing grid.
