  • HYDROKINETIC ENERGY DEVICE
    Publication number: 20220325688
    Abstract: Systems and method for a hydrokinetic energy device. A hydrokinetic energy device includes a main body including two main wing-shaped spars mounted upon a rotating central hub, and rotatable spar tip turbines mounted at or near an end of each of the main wing-shaped spars, the main wing-shaped spars driving the rotatable spar tip turbines through water, each of the rotatable spar tip turbines including a direct-drive generator and power conversion system that transfers power from a rotating rotatable spar tip turbine to the central hub where the voltage is stepped up and amperage is reduced.
    Type: Application
    Filed: June 16, 2022
    Publication date: October 13, 2022
    Inventors: David J. Duquette, Kimbal Anderson Hall
