A buoyancy means and apparatus for reducing friction in rotational devices, particularly electric generators and or turbines. This feature is critical in hydroelectric power plants and ocean energy projects where the rotating weights are significant. Flotation devices are affixed to rotational devices and submerged into a heavy fluid encased within a chamber that does not interfere with the normal operation of the said rotational device. Vibration is also reduced, allowing for more precise operation and a longer life cycle for moving parts.
