| 20090260358 | Thermoelectric Energy Conversion System - A system for generating electrical energy using a naturally occurring temperature difference is disclosed. The system provides electrical energy by thermally coupling a conduit that conveys hot material from a petroleum reserve and cold deep-level water to opposing sides of a thermoelectric element. The thermoelectric element generates electrical energy based on the temperature difference between these two surfaces. | 10-22-2009 |
| 20090308582 | Heat Exchanger - A heat exchanger and a method for fabricating the heat exchanger are disclosed. The heat exchanger comprises a heat exchanger core that is formed from a plurality of stacked aluminum panels that are joined together via friction stir welding. Each panel in the core is formed from at least two aluminum extrusions that are joined to one another via friction stir welding. | 12-17-2009 |
| 20100000214 | Petroleum-based Thermoelectric Energy Conversion System - A system for generating electrical energy based on a temperature differential between petroleum products extracted from a geothermal reservoir and water from a region of a body of water is disclosed. Some embodiments comprise a submerged pump and a submerged OTEC system, wherein the OTEC system provides locally generated electrical energy to the pump. | 01-07-2010 |
| 20100180924 | Floating Platform with Detachable Support Modules - A floating support that can be joined with a floating platform while the floating platform is at a deployment location is disclosed. The support provides functionality to the floating platform in order to change, augment, upgrade, or diversify the platform's overall capability. In some embodiments, the present invention eases the serviceability of the platform by enabling a first support that has diminished capability to be readily replaced by a second support having superior capability—without removing the floating platform from its deployment location. In some embodiments, the present invention enables platform operation that is analogous to “plug and play” electronics systems. Further, in some embodiments, hydrodynamic performance of the floating platform can be changed with the addition or removal of one or more floating supports. | 07-22-2010 |

| 20110011570 | Heat Exchanger and Method for Making - A hybrid plate-fin heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed. The hybrid plate-fin heat exchanger comprises a plurality of plates, each of which comprises channels for conveying the first fluid. Fins are brazed onto each plate, wherein the fins define a plurality of flow channels for the second fluid. The plates are joined to one another via friction-stir welding in such a way that the brazed regions are fluidically isolated from the first fluid during operation. As a result, the heat exchanger is suitable for use in applications that use a first fluid, such as seawater or geothermal fluid, which is corrosive for the brazed regions. | 01-20-2011 |
| 20110011572 | Helical Tube Bundle Arrangements for Heat Exchangers - A heat exchanger comprising helically wound tube bundles is disclosed. The helically wound tube bundles are joined with tube sheets to define a primary working fluid system that is fluidically isolated from a secondary working fluid system. The tube sheets and tubes are formed of the same material, which facilitates their joining by means of joints that are substantially galvanic corrosion-resistant joints. | 01-20-2011 |
| 20120080175 | Manifolding Arrangement for a Modular Heat-Exchange Apparatus - A heat-exchanger module that conveys a fluid through one or more heat exchangers with little or no pressure drop is presented. The heat-exchanger module comprises a first manifold that smoothly channels the fluid from a fluid source to each of the heat exchangers. The heat-exchanger module further comprises a second manifold that smoothly channels the fluid from the heat exchangers to a fluid sink. The manifolds are dimensioned and arranged to mitigate development of pressure drops in the fluid flow. | 04-05-2012 |

| 20120080164 | Heat-Exchange Apparatus with Pontoon-based Fluid Distribution System - A pontoon that includes infrastructure for fluidically coupling a heat exchanger or heat exchanger module into each of the seawater and working-fluid distribution systems of an OTEC power generation system is provided. In some embodiments, a pontoon comprises: (1) a first passage for conveying seawater between a first port and a second port at which a heat exchanger module can be connected; and (2) a conduit and connectors for connecting the heat exchanger module and the working fluid circulation system—even while the heat exchanger module is submerged. In some embodiments, pontoons in accordance with the present invention enable heat exchangers or heat exchanger modules to be added or removed to an OTEC system without disrupting the operation of other heat exchangers or heat exchanger modules in use in the OTEC system. | 04-05-2012 |
