1. A hydrokinetic turbine engine comprising:
(a) a primary turbine driven to rotate by a hydrokinetic flow, (b) a secondary turbine, driven by the working fluid flowing through a closed-circuit, that provides mechanical power as the output of the engine, (c) said closed-circuit working fluid flow system comprised of two or more tanks attached to said primary turbine so as to rise and fall with rotation of said primary turbine, and a flow network connecting said tanks through which working fluid drains from an upper tank through one or more conduits into an intake manifold with a flow control capability that only accepts fluid from said tanks and directs the flow into said secondary turbine from which the working fluid exits into an exhaust manifold with a flow control capability that directs working fluid through one or more conduits toward the tanks but will not accept fluid flow from the tanks. |
