Abstract: The present invention relates to cushioning apparatus having a plurality of intersecting columns, the columns being formed from a thermoplastic, silicone, two-part, or other gel material. The cushioning apparatus are extremely strong and durable yet provide an improved cushioning apparatus. The intersecting columnar configuration of the cushioning apparatus allow for weight to be shared with neighboring column walls. When force is exerted on the columns, the column walls are designed to buckle in the areas of greatest pressure. The column buckling diffuses energy from the areas of highest pressure effectively eliminating pressure points. As the polymer gel collapses within the column walls, the column walls essentially collapse at least partially in a lateral direction allowing pressure to flow away from the areas of greatest pressure to areas of lesser pressure. This provides an improved cushioning surface on which a user can sit, sleep, or other types of cushioning can be provided.

Abstract: A closed-loop cooling system is provided for a hydrogen/oxygen based combustor. A combustion reaction between hydrogen and oxygen in the combustor produces steam. The steam is used to generate work from a turbine shaft, which is used to drive a propulsion system for the underwater vessel. After the steam passes through the turbine, the steam is cooled back to liquid water by a condenser that uses a seawater cooling loop to cool the steam into cold water. The cold water is then injected into the combustor, and pumped into passages along the walls of the combustor, thus absorbing the heat. The cold water absorbs this heat until it becomes hot water or steam, which is then injected into the combustor with the hydrogen and oxygen to act as a diluent, thus reducing the reaction temperature of the hydrogen/oxygen combustion reaction. The reaction produces more steam, and the cycle repeats.
