Abstract: An invention for capturing and converting the hydro kinetic energy in ocean and tidal currents into mechanical energy for generating electricity. An internal turbine enclosed in a external turbine cylinder rotates opposite of internal turbine. Current is compressed into high pressure within internal turbine, the high pressure is vented into the rear low pressure side of external turbine producing additional energy. The internal and external turbines are enclosed in a cowling to maximize current through both counter rotating turbines. Permanent magnet rings are coupled to both turbine tips that rotate peripheral to stators. The cowling and turbines are balanced around the main center shaft, it is finned at the rear to steer the apparatus into the current. Counter rotation produces a neutral output torque with increased energy output that is transmitted via underwater cable to onshore grid.
