Generator with falling stator

A hydroelectric generator comprising:

• a rotatable pressure vessel, said pressure vessel having an inner and outer surface;
• a plurality of first magnets disposed on said inner surface of said pressure vessel;
• a biasing structure extending at least partly along a lengthwise dimension of said pressure vessel, said biasing structure having an axis of rotation that is within a circumference of said pressure vessel, a center of gravity of said biasing structure at a radius away from a center axis of said pressure vessel;
• and
• a plurality of armature coils disposed on said biasing structure and positioned such that relative motion between said first magnets and said plurality of armature coils induces a current in said armature coils.

A method of generating hydroelectric power with a generator including a pressurized rotatable pressure vessel and a biasing structure that is within the pressure vessel and extends at least partly along a lengthwise dimension of the pressure vessel, the method comprising:

• at least partially submerging the generator underwater;
• allowing the pressure vessel to rotate relative to the biasing structure;
• providing a current to electromagnets disposed within the pressure vessel;
• and
• controlling an operating angle of the biasing structure by adjusting the current.
