Provided are, among other things, systems, methods and techniques for generating energy. According to one representative embodiment, a main housing includes an air chamber having an open bottom, and a paddlewheel is attached to the main housing so that the paddlewheel is free to rotate and thereby generate kinetic energy. An anchor is attached to the main housing, and an electrical generator which converts the kinetic energy of the paddlewheel into electrical energy is coupled to the paddlewheel. An upper portion of the paddlewheel is enclosed by the air chamber. When the main housing is submerged underwater and maintained in a level orientation, air within the air chamber remains trapped within the air chamber, thereby reducing resistance to rotation of the paddlewheel.

1. A system for generating energy, comprising: a main housing;a rotating member attached to the main housing that rotates in response to water current, thereby generating kinetic energy;an anchor attached to the main housing; andan electrical generator, coupled to the rotating member, which converts the kinetic energy of the rotating member into electrical energy,wherein the main housing is submerged underwater and movably tethered to the anchor, andwherein each of the main housing and the anchor has variable buoyancy, permitting sinking and then refloating as desired. 2. A system according to claim 1, wherein the main housing includes a rudder, whereby when the main housing and attached rotating member are disposed in a water current, the rudder automatically adjusts a position of the main housing so that the rotating member is directly facing the water current. 3. A system according to claim 1, further comprising an underwater hydrogen-generation system, coupled to the electrical generator, which uses the generated electrical energy to produce hydrogen from water, and an underwater hydrogen-storage tank. 4. A system according to claim 1, wherein the rotating member comprises a paddlewheel that is horizontally oriented when in use. 5. A system according to claim 1, further comprising a second energy-generating unit that includes a second housing and a second rotating member and that is movably tethered to the housing, and wherein the second energy-generating unit has variable buoyancy, permitting sinking and then refloating as desired. 6. A system according to claim 1, wherein each of the main housing and the anchor is made of concrete. 7. A method of generating energy, comprising: towing an energy-generating unit and an anchor to an installation site, the energy-generating unit including a main housing, a rotating member attached to the main housing that rotates in response to water current, thereby generating kinetic energy, and an electrical generator, coupled to the rotating member, which converts the kinetic energy of the rotating member into electrical energy;attaching the energy-generating unit to the anchor;releasing air from the anchor, thereby sinking the anchor; andreleasing air from the energy-generating unit, thereby sinking the energy-generating unit,wherein upon completion of sinking the anchor and the energy-generating unit, the energy-generating unit is submerged underwater and movably tethered to the anchor, andwherein each of the energy-generating unit and the anchor has variable buoyancy, permitting sinking and then refloating as desired. 8. A method according to claim 7, further comprising a step of manufacturing the energy-generating unit and the anchor in and on the water prior to said towing step. 9. A method according to claim 7, wherein the energy-generating unit is tethered to the anchor using at least one anchor cable, and further comprising a step of adjusting the at least one anchor cable after the anchor reaches the bottom of the water. 10. A method according to claim 9, wherein said adjusting comprises leveling components of a system that includes the energy-generating unit and the anchor. 11. A method according to claim 7, wherein the energy-generating unit is tethered to the anchor using at least one anchor cable, and further comprising a step of pumping air into the energy-generating unit after the anchor reaches the bottom of the water so as to pull the at least one anchor cable taut, thereby stabilizing a system that includes the energy-generating unit and the anchor. 12. A method according to claim 7, wherein the main housing includes a rudder, whereby when the main housing and attached rotating member are disposed in a water current, the rudder automatically adjusts a position of the main housing so that the rotating member is directly facing the water current. 13. A method according to claim 7, wherein the rotating member comprises a paddlewheel that is horizontally oriented when in use. 14. A method according to claim 7, further comprising steps of: attaching a second energy-generating unit that includes a second housing and a second rotating member to the energy-generating unit; andreleasing air from, and thereby sinking, the second energy-generating unit,wherein upon completion of sinking the second energy-generating unit, the second energy-generating unit is submerged underwater and movably tethered to the energy-generating unit, andwherein the second energy-generating unit has variable buoyancy, permitting sinking and then refloating as desired. 15. A method according to claim 7, wherein an underwater hydrogen-production unit receives electricity from the energy-generating unit and uses the electricity to remove hydrogen from surrounding water. 16. A method according to claim 15, wherein an underwater transport/storage barge receives the hydrogen from the hydrogen-production unit and stores the hydrogen. 17. A method according to claim 16, further comprising steps of: re-floating the transport/storage barge;disconnecting the transport/storage barge from the hydrogen-production unit after the transport/storage barge has been re-floated and connecting a replacement transport/storage barge to the hydrogen-production unit;sinking the replacement transport/storage barge; andtowing away the transport/storage barge. 18. A method according to claim 7, wherein said attaching step is performed prior to said towing step. 19. A method according to claim 7, wherein each of the main housing and the anchor is made of concrete.
