TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Component: The turbine also includes an axis into which the blades are arranged radially symmetrical. The distal edges of the blades form a vacant hole whose center is the axis (6) or form a virtual point whose center is the axis. The blades allow for bi-directional energy capture. The bearing is a tapered roller bearing that is a combination of thrust bearing and a cylindrical roller bearing, hydrostatic bearing, or magnetic bearing. The shell further includes buoyancy mechanism, thus it is buoyantly neutral and the weight and drag associated with the affect of gravity on the turbine is partially or fully negated. The buoyancy mechanism includes vacant cavity within the body of the shell, and a mechanical or servo valve for filling and discharging the vacant cavity with ballast. The shell further includes an aeration mechanism. The outer surface of the blades is irregular to produce a riffling effect, and increase efficiency of the blades. The rotational energy connecting element is a gear or belt with teeth. It is connected to a rotary transmission mechanism, which is a gear box. The supporting structure further includes a hydraulic mechanism to elevate and lower the turbine, and to rotate, with flows, the turbine. The outer housing is made from concrete and comprising a foundation. It is submersible and comprising a pipeline for exporting the hydrogen, purified water, or electricity. The pipeline is connected to an onshore distribution mechanism or to moorings where vessels may load the hydrogen. The outer housing is a dam for replacing the Francis and Kaplan turbines used in hydroelectric power plants. It is a breakwater, harbor wall, oil derrick, or exhaust system that is a component of a steam engine or steam generator. The supporting structure further includes a grate to deflect debris and fish too large to safely pass through the turbine. The turbine further includes a funnel comprising a funnel like structure, and a rib that channels the flow of passing fluids and gases in a direction perpendicular to the surface of a turbine's blades to enhance the efficiency of any turbine. The funnel like structure includes a hollow cylinder with two vacant holes at opposing ends. One vacant hole has a larger diameter than the other. The electric generator is a Hydroelectric Turbine For Producing Electricity From A Water Current described in Williams;US6648589B2;Nov.18,2003, Hydroelectric Power plant described in Williams;US38336E;Dec.2,2003, or Hydroelectric Power plant described in Williams;US5592816;Jan.14,1997.    TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Material: The tapered roller bearing is made from ceramic.    TECHNOLOGY FOCUS - METALLURGY - Preferred Material: The cylindrical shell, blades, and grate are fabricated from composite materials, titanium steel veneer, or stainless steel veneer.
