摘要:
Systems and methods for collecting, storing, and conveying aqueous thermal energy are disclosed. In a particular embodiment, a floating film retains solar energy in a volume of water located under the film. A series of curtains hanging from a bottom surface of the film define a passage between a periphery of the film and a center of the film to direct the heated water at the center of the film. The heated water is circulated to deliver the heat to a dissociation reactor and/or donor substance. The donor is conveyed to the reactor and dissociated.

A heat exchanger for thermally coupling a first fluid and second fluid is disclosed. The heat exchanger comprises plates comprising cores of thermally conductive graphite foam. A plurality of conduits for conveying the first fluid is formed in each core. Each plate further comprises thermally conductive barriers that sandwich the core, wherein the barriers are substantially impervious to r the first fluid and second fluid. Plates are stacked in a frame such that the frame and plates collectively define a plurality of channels for conveying the second fluid. Heat is exchanged between the primary fluid and the secondary fluid through the graphite-foam cores and barriers.Heat exchangers in accordance with the present invention can be lighter, have improved ratio of heat transfer surface density to heat exchanger volume, be lower cost, and/or be smaller for a given heat transfer capability than prior-art heat exchangers.

The present invention relates to a floating structure comprising at least a closed space (10), a hull in the shape of a concrete cofferdam (12) having an external delimiting surface intended to be exposed to surrounding water, and a function for heating of the space comprising a heat pump connected to a closed circuit for circulating heat transport medium. At least one collector hose (14) for the circulating heat transport medium is provided in recesses in the concrete such that the cross section of the collector hose is located entirely within an outer outline of the cofferdam, whereby heat from surrounding water is absorbed by the collector hose and used for heating of the space. The invention also relates to a method of moulding a concrete cofferdam (12) adapted to be a hull of a floating structure.

A thermodynamic system and method for performing work includes a working fluid and a fluid pump for pumping the working fluid through a cycle. A thermal input supplies heat to the working fluid. An expansion device downstream of the thermal input converts at least the heat of the working fluid to useful work. A heat exchanger downstream of the expansion device has a first portion to transfer heat from downstream said expansion device to a second portion at or upstream of said thermal input. A conversion device expands the working fluid with constant enthalpy from a higher to a lower pressure.
