Abstract: A device configured for the production of hydrokinetic energy that allows the efficient capture of energy from fluid in motion, especially slow flowing fluids. The device features an innovative structural design and drive train system as well as redundancy, which allows the device to be deployed in position, placed in service and maintained over its lifetime through the use of remotely operated vehicles. The device features one or more turbines, each turbine having an open center tube. The device features a buoyancy system including a plurality of thin walled modular buoyancy chambers with a redundant (re)pressurization system and remotely operated vehicle replaceable bladder modules. Structure cavities of the device are capable of storing energy via processed energy storage liquids such as hydrogen or via gas compression in tanks and then exporting the stored energy or reconverting the stored energy into electricity.

Abstract: A hydro or aero kinetic energy device (100) includes a hydrofoil-shaped blade and rotor system (11) made from composite and membrane flexible materials with an innovative system design to create a large, but relatively light-weight hydrokinetic turbine that achieves disruptively low deployment cost and low Cost of Electricity (COE), in high volumetric flow rate, low velocity (1-3 m/s) marine or air currents. The system (100) continually senses the current (12, 14) at the deployment site and based on the current profile, adjusts the pitch of the blades in real-time, thereby leveling out the forces on the turbine rotor. The hydrokinetic energy device turbine (100) may be assembled onshore, on the way to the deployment site or at the deployment site Further, be turbine may include a remote control receiver mechanism (77), that allows an operator to remotely controlled the maneuvering and other aspects of the turbine (100) during deployment, operation and maintenance.
