An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied from a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes a compartment including an emission source of the fuel and a first detector arranged in the compartment to detect the fuel. If the first detector detects that a concentration of the fuel in the compartment is equal to or greater than a first threshold value, a power supply to a non-explosion-proof device in the compartment is stopped.

A portable marine camping apparatus that is configured to provide a camping and recreational platform that can navigate waterways wherein the present invention is inflatable so as to facilitate easy transport thereof. The present invention includes a deck assembly that is superposed a hull portion wherein the deck assembly is planar in manner and includes rigid high pressure air chambers. Integrally formed with the deck assembly is a tent module wherein the tent module is manufactured from inflatable components and is deployed during inflation of the deck assembly. A boat unit is operably coupled to the rear of the deck assembly and is configured to provide propulsion of the portable marine camping apparatus 100. A fire module is formed with the deck assembly and is manufactured from steel grate panels. The fire assembly further includes a receptacle for receiving combustible materials.

A stowable propulsion system for a marine vessel. A base is configured to be coupled to the marine vessel. A shaft has a proximal end and a distal end with a length axis defined therebetween, where the shaft is pivotably coupled to the base and pivotable about a transverse axis between a stowed position and a deployed position, and where the distal end is closer to the marine vessel when in the stowed position than in the deployed position. A gearset is engaged between the shaft and the base, where the gearset rotates the shaft about the length axis when the shaft is pivoted between the stowed position and the deployed position. A propulsion device is coupled to the distal end of the shaft. The propulsion device is configured to propel the marine vessel in water when the shaft is in the deployed position.

A universal chemical processor (UCP) including a reactor vessel with a main chamber, comprises inlets for feedstock, a fluidizing medium and reactants. The UCP further includes a reactive X-ray chemical processor (RXCP) having a large area hollow cylindrical cold cathode in the main chamber, a grid positioned concentrically with respect to the cathode, and an anode positioned concentrically with respect to the cathode and grid. In operation, when activated, the cathode of the RXCP emits electrodes onto the anode, which then emits X-rays into a radiation zone within the main chamber capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing organic materials within the radiation zone, and wherein, a fluidized bed is supported in the main chamber when the fluidizing medium and feedstock are supplied. The RXCP and the fluidized bed portions can be operated separately or in conjunction to achieve unanticipated results.
