Abstract: 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.
