Hydrokinetic Savonius Jet Turbine with Additional Inner Blades

Hydrokinetic Savonius Jet Turbine with Additional Inner Blades
Free Flow Turbine uses a "shrouded turbine" design that channels water through the turbine's
blades. Water passes through a rotor blades that are usually designed for a slow spin
rate to minimize fish strikes.

But we find out at least two disadvantages of so called ducted/shrouded/diffuser
augmented hydro kinetic Turbine.

First is the complicated costly design leads to costly maintenance.
The second is danger for under water life.

Our radical new design includes duct free turbines with JET stream assisting rotation. Usually we are designing axial flow turbines with 3D rotors with tapered jet blades. As you can see at video here a cross flow Savonius turbine have been upgraded to operate by additional JET mode.

Technologies to harness ocean current energy are at an early developing stage, and only a few prototypes and demonstration units have yet been tested. Ocean currents are potentially significant and currently untapped resource of energy. Ocean currents thus contain an abundant source of energy that can be captured and converted to a usable form. This paper discusses the performance of three different types of Savonius rotors used as water current turbines. Rotors design and test results in a tow tank are presented. All three rotors have same cross sectional area. Test results shows that double stage rotor has lower cut-in speed and produces higher torque when compared to single and three stage rotor design. These rotors were tested to determine a suitable water current turbine for a micro seafloor power generation system.
