  • Patent number: 10269462
    Abstract: An offshore, floating, moored, nuclear power generating and multi-purpose platform is disclosed. In a preferred embodiment, the invention is a spar platform with multi-purpose, topside decks, attached to a submerged dry tank that further includes: reactor generator deck(s), power plant main control deck, and central plant deck, that are all integrated within a watertight ballast hull. The invention further includes cells that are modular for facilitating factory assembly and ultimate construction in a shipyard environment. Reactor vessels are typical naval nuclear reactor having a time tested outstanding safety record. A plurality of reactor generator modules operate independently and collectively. Multipurpose topside decks house vessel command, crew, and any ancillary and co-generation equipment. The present invention, constructed in a multi-path manufacturing process, provides exceptional economic, environmental, sustainability, security, safety, and operational benefits to users.

  • Publication number: 20180254115
    Abstract: An offshore, floating, moored, nuclear power generating plant and multi-purpose platform is disclosed herein. In a preferred embodiment, the invention consists of a spar or cell spar platform with multi-purpose, all weather topside decks, attached to a submerged “dry tank” that further includes: reactor generator deck(s), power plant main control deck, and central plant deck, that are all integrated within a watertight ballast hull. The invention design further includes cells that are modular for facilitating factory assembly and ultimate construction in a shipyard environment. Reactor vessels are typical naval nuclear reactor having a time tested outstanding safety record. A plurality of reactor generator modules are interconnected and operate independently and collectively and are transmitted by a plurality of high voltage direct current (HVDC) submarine cables through a transformer to the electrical grid. Multipurpose topside decks house vessel commend, crew, and any ancillary and co-generation equipment.

  • Publication number: 20140140466
    Abstract: Disclosed is an offshore, manned, scalable, modular, floating, moored, nuclear power generating plant and multipurpose platform. The present invention is comprised of a Main Plant Control Deck, Central Plant Deck, and submerged Reactor-Generator Deck(s) integrated into the structure of a Spar or Cell Spar Platform. The Reactor-Generator decks are comprised of a plurality of modular, Naval Nuclear Pressurized Water Reactor Modules. Electricity generated is transmitted via submarine High Voltage Direct Current Cables to shore. Ancillary, co-generated services, e.g. desalinated water, are transmitted to shore via submarine pipelines. Multipurpose Topside Decks house vessel command, crew, and any ancillary and co-generation equipment. The present invention, constructed in a multi-path manufacturing process, provides exceptional economic, environmental, sustainability, security, safety, and operational advantages over the current art of power generation.

  • Publication number: 20120192343
    Abstract: A combination toilet and stool/table is disclosed. This structure includes opposing and parallel front and rear walls, along with opposing and parallel side walls. The side walls are capable of folding so that the structure can be portable. A foldable seat is attached to the rear wall and is secured to the structure by securing tabs located along the top edge of the side walls, along with a front safety-lock tab securing the front edge of the foldable seat with the front wall. A bag for receiving waste, garbage and other items can be placed within the interior of the structure. Access to the bag is through an opening in the foldable seat. The foldable seat includes a lid that can be moved between an open position and a closed position.

  • Patent number: 4199957
    Abstract: An evaporator assembly for a heat transfer unit comprises a sealed thermally conductive container and a duct mounted in the container. Channels are formed between the walls of the duct and those of the container and thermal transfer fins are attached to the inside surfaces of the walls of the container and located in the channels. An evaporator extends transversely across the width of the duct and a defrosting heater bank is located downstream from the evaporator in the duct. Suitable fans and a drive motor are mounted at one end of the duct to circulate air or other gas through or across the evaporator, through the duct, and through the channels. During use of the assembly, heat is transferred from the container walls and the fins to the circulating air and the heat is then extracted from the air or gas by thermal transfer through the evaporator. The assembly provides a buffer between the heat source and the evaporator in order that the evaporator may operate in a near moisture free environment.
