Abstract

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.

Claims (26)

1 . A system comprising:

a capture device coupled to an enclosure, the capture device including a rotor shaft and a plurality of blades coupled to the rotor shaft, wherein the plurality of blades are arranged to receive a flow of water when the enclosure is submerged in a body of water, wherein the flow of water causes the plurality of blades to rotate the rotor shaft;

a transfer device extending lengthwise from a first end to a second end of the transfer device, wherein 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, wherein the second end is located outside the enclosure

a pump disposed upstream of the plurality of blades and configured to increase a pressure of the water flowing toward the capture device;

a conveyer belt, wherein the plurality of blades are disposed on the conveyer belt, wherein the flow of water includes a first stream of water from the pump that causes the plurality of blades to rotate the conveyer belt;

a plurality of rotor shafts disposed in the conveyer belt, wherein the rotor shaft is a first rotor shaft of the plurality of rotor shafts, wherein the conveyer belt rotates the plurality of rotor shafts, wherein the transfer device is a first transfer device and the torque is a first torque, wherein the first transfer device extends lengthwise to transfer the first torque from the first rotor shaft to a first destination; and

a second transfer device coupled to a second rotor shaft of the plurality of rotor shafts, wherein the second transfer device extends lengthwise to transfer a second torque of the second rotor shaft to a second destination.

2 . The system of claim 1 , wherein the second end is coupled to a generator configured to generate electrical power using the transferred torque.

3 . The system of claim 2 , wherein the generator is disposed outside the body of water.

4 . The system of claim 1 , wherein the second end of the transfer device is located outside the body of water.

5 . The system of claim 1 , wherein the capture device is disposed inside the enclosure.

6 . The system of claim 1 , wherein the transfer device comprises a first pipe extending lengthwise, in a first direction, away from the first end.

7 . The system of claim 6 , wherein the transfer device comprises a second pipe extending lengthwise, in a second direction, away from the first pipe.

8 . The system of claim 1 , wherein the transfer device comprises a flexible cable extending lengthwise between the first end and the second end of the transfer device.

9 . The system of claim 8 , wherein the transfer device comprises a wire disposed inside the flexible cable and configured to transfer the torque of the rotor shaft by rotating inside the flexible cable.

10 . The system of claim 9 , wherein the wire includes an auger wire.

11 . The system of claim 9 , wherein the transfer device comprises a suspension apparatus disposed in the flexible cable and configured to induce a magnetic force on the wire so as to prevent or reduce physical contact between the flexible cable and the wire in at least a lengthwise portion of the flexible cable.

12 . The system of claim 1 , further comprising: an intake port disposed along a periphery of the enclosure to transport the flow of water into the enclosure and toward the capture device.

13 . The system of claim 1 , wherein the pump is a turbopump.

14 . The system of claim 1 , wherein the pump is a hydraulic pump.

15 . The system of claim 1 , wherein the second transfer device is configured to transfer the second torque to the pump, wherein the second torque powers the pump.

16 . The system of claim 15 , wherein the rotor shaft is a first rotor shaft, wherein a first stream of water that drives rotation of the first rotor shaft is different than a second stream of water that drives rotation of a second rotor shaft having the second torque.

17 . The system of claim 1 , further comprising:

a tank storing water, wherein the pump is a first pump configured to pump water from the tank to form the first stream of water flowing above the conveyer belt to actuate the plurality of blades; and

a second pump configured to pump water from the tank to form a second stream of water flowing below the conveyer belt to actuate the plurality of blades.

18 . The system of claim 1 , wherein the transfer device is a first transfer device, and the second transfer device extends lengthwise from a first location of the second end of the first transfer device to a second location, wherein the second transfer device is configured to transfer a portion of the torque from the first transfer device to the second location.
