Systems and methods for power distribution and harnessing of marine hydrokinetic energy
An example system comprises an enclosure configured to be submerged in a body of water. The system also comprises a capture device coupled to the enclosure. The capture device includes a rotor shaft and a plurality of blades coupled to the rotor shaft. The plurality of blades are arranged to receive a flow of water when the enclosure is submerged in the body of water. The flow of water causes the plurality of blades to rotate the rotor shaft. The system also comprises a transfer device extending lengthwise from a first end to a second end of the transfer device. The transfer device is mechanically coupled to the capture device at the first end and configured to transfer a torque of the rotating rotor shaft from the first end to the second end. The second end is located outside the enclosure.
