A deep-water power generation system includes an initially evacuated sphere having walls of suitable strength or reinforcement for maintaining its structural integrity in deep-water pressures; a power axle extending from a north pole thereof to below a south pole of the sphere; blades of a turbine secured upon a support frame secured to the axle in a latitudinal plane of the sphere; and inlet ports positioned at the plane of the blades of the turbine and receiving an inflow of ambient deep water against the blade. The fluid flow induces rotation of the blades power axle secured to the frame. A thrust deck is rigidly secured, within the sphere, to the power axle and above the turbine and a generator is secured upon the thrust deck at the south pole of the sphere spirally expelling water from the south pole of the system.
