Systems and methods for capturing renewable energy are disclosed herein. An example system can include a concave receptacle configured to float on top of water, a turbine positioned centrally with the concave receptacle, a buoyancy control system having a pump and one or more vessels, a controller having a processor and memory for storing instructions, the processor executing the instructions to cause the buoyancy control system to submerge the concave receptacle under the water by filling the one or more vessels with a fluid using the pump and cause the buoyancy control system to release the fluid from the one or more vessels and allow the concave receptacle to travel upwardly so that water is directed into the turbine to produce electricity.

An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.
