Abstract: A device for cultivating marine species is described. The device includes a structure, a buoyancy device coupled to the structure, a panel coupled to the structure, and an assembly coupled to the structure. The panel is configured to capture solar energy. The assembly includes a support frame, a first sprocket coupled to the support frame, a first motor coupled first sprocket, a first chain coupled to the first sprocket, and a container coupled to the chain. The container is configured to store marine species. The container is configured to be moved by the first motor. The device may include a cleaning device. The device may include an aerating device. The device may include a computing device and an energy storage device. The energy storage device may be coupled to the computing device and the panel.

Abstract: An amphibious vehicle that includes a hull comprising a plurality of hull sections, a hull positioning device configured to position one of more hull sections from the plurality of hull sections into a plurality of positions, a first propulsion device configured to move the amphibious vehicle when the amphibious vehicle is on land, a second propulsion device configured to move the amphibious vehicle when the amphibious vehicle is in a body of water, and a buoyancy device configured to provide buoyancy for the amphibious vehicle when the amphibious vehicle is in the body of water.
