EnCurrent Turbine
The EnCurrent Turbine technology is based on the Darrieus wind turbine. It is a cross flow turbine. When the turbine rotor is placed within a water current the hydrofoils generate a lift vector in the forward orientation which can be captured by the shaft as a positive rotation. The hydrofoils experience their maximum forward torque at the top and bottom of their rotation when the water moves past tangentially. The turbine rotates in the same direction regardless of the direction of the water current. It rotates at a very low speed between 2-2.5 times the speed of the water in which it is submerged. A permanent magnet generator is mounted on the turbine shaft to convert the torque generated by the rotor into electricity. The 250 kW device has a width of 7.4 meters and and height of 7.4 meters and is designed for water speeds of 3 m/s.
