Abstract: A system and method for controllably connecting a marine vessel's native fresh water network to its raw water network in order to flush the raw water network. The controllable connection is provided by a hydrostatic lock—which ensures that water can only flow in the direction from the fresh water network to the raw water network and never in the opposite direction. A system controller directs the fresh water flush cycle and other operations.

Abstract: A solar-powered vending machine includes a photovoltaic (PV) panel assembly connected to a vending machine. The PV panel assembly includes a panel subassembly and mounting subassembly connecting the panel subassembly to the vending machine. The panel subassembly includes a plurality of PV panels foldably interconnected to expand to a deployed width greater than a vending machine width and collapse to a stowed width less than or approximately equal to the vending machine width. The mounting frame supports the PV panels for movement between a deployed position above the vending machine and a stowed position adjacent a side of the vending machine.
