Abstract: An improved ocean thermal energy conversion (OTEC) system which includes a novel combined evaporator/condenser. The combined evaporator/condenser further includes a plurality of evaporator spouts and a mist eliminator, wherein the pressure is maintained across the plurality of evaporator spouts. The OTEC system also generates fresh water as a primary product and generates only enough electricity, as a secondary product, to operate the OTEC system itself.

Abstract: A hybrid ocean thermal energy conversion (OTEC) system, including an energy generation sub-system for receiving warm sea water, evaporating a working fluid at a natural depth of the received warm sea water to produce a working vapor, and generating energy from the working vapor and a pumping sub-system for pushing cold sea water up to a natural depth of the received warm sea water and condensing the working vapor with the cold sea water.

Abstract: The disclosure concerns a non-thermal expanding spool for use in oxidation of green spun carbon fibers, subsequent to fiber spinning and prior to carbonization. The spool is a hollow tube formed on a mandrel from a multi-ply, multi-directional woven graphite cloth impregnated with a thermosetting resin, e.g. polyimide. Then a plurality of hoop fiber filaments are wrapped around it which also become impregnated with the thermosetting resin. The resulting tube or spool is then baked or cured at elevated temperatures. The baked spool is then provided with a large number of geometrically or randomly disposed holes or openings.
