Definitions

  • Figure 4 is a cross-sectional schematic view of a portion of a representative film assembly 305 including schematic representations of components that interact with the film assembly 305, one or more gas radiation trapping and/or insulation inventories (e.g., the gas space 303), and/or the water volume 312. Some of these components may be mounted on or otherwise carried by the support 300, a portion of which is visible in Figure 4. As illustrated, the film assembly 305 floats at or near the ocean surface 240 due to the buoyancy of the film assembly itself, and/or constituents in the cells 304.
  • gas radiation trapping and/or insulation inventories e.g., the gas space 303
  • the fluid in the passages can be maintained at a sub-atmospheric pressure, allowing it to vaporize at a lower temperature, which can significantly increase the heat capacity of the fluid as it absorbs heat.
  • the fluid can then be condensed to release the heat, in a process that is readily controlled.
  • the fluid can be condensed at a specific location (e.g., at a reactor or other device that benefits from the transferred heat) by increasing the fluid pressure at that location.
  • the controller 258 provides adaptive adjustments to the velocity and the momentum of the water volume 312 (and/or other fluid volumes), providing a "flywheel" effect and in conjunction with removal for heat-exchange purposes will continue to deliver tailored (e.g., optimized) amounts of warm water toward the inner peripheral curtain 306a during periods of decreased solar warming, such as during cloudy periods or at night.
  • sulfur dioxide can be processed in a non-combustion thermal reactor to produce sulfur and oxygen
  • carbon dioxide can be processed to produce carbon and oxygen
  • the resulting dissociation products can include a structural building block and/or a hydrogen-based fuel or other dissociated constituent.
  • the structural building block includes compositions that may be further processed to produce architectural constructs.
  • the structural building blocks can include compounds or molecules resulting from the dissociation process and can include carbon, various organics (e.g. methyl, ethyl, or butyl groups or various alkenes), boron, nitrogen, oxygen, silicon, sulfur, halogens, and/or transition metals.
  • the building block element does not include hydrogen.
  • the radiative energy R can include a first portion R1 that is generally aligned parallel with the spaced-apart layered structures 2158 and accordingly passes entirely through the re-radiation component 2150 via the gaps 2153 and enters the reaction zone 21 12 without contacting the re-radiative material 2152.
  • the radiative energy R can also include a second portion R2 that impinges upon the re-radiative material 2152 and is accordingly re-radiated as a re-radiated portion RR into the reaction zone 21 12.
  • the reaction zone 21 12 can accordingly include radiation having different energy spectra and/or different peak wavelength ranges, depending upon whether the incident radiation R impinged upon the re-radiative material 2152 or not.
  • the outer screw 4131 rotates about a central rotation axis 41 15, as indicated by arrow O. As it does so, it carries at least one reactant 4134 (e.g., a gaseous, liquid, and/or solid reactant) upwardly and to the right as shown in Figure 10C, toward the reaction zone 41 1 1 . As the reactant 4134 is carried within the outer screw threads 4133, it is also compacted, potentially releasing gases and/or liquids, which can escape through louvers and/or other openings 41 18 located annularly outwardly from the outer screw 4131 . As the reactant 4134 becomes compacted in the outer screw threads 4133, it forms a seal against an inner wall 41 19 of the vessel 41 10.
  • reactant 4134 e.g., a gaseous, liquid, and/or solid reactant
  • the product removal system 4140 can include an inner screw 4141 positioned in the first axial opening 4135 within the outer screw 4131 .
  • the inner screw 4141 can include an inner screw shaft 4142 and inner screw threads 4143.
  • the inner screw 4141 can also rotate about the rotation axis 41 15, as indicated by arrow I, in the same direction as the outer screw 4131 or in the opposite direction.
  • the inner screw 4141 includes a second axial passage 4145 having openings that allow the gaseous product G to enter.
  • the gaseous product G travels down the second axial opening 4145 to be collected and, in at least some instances, further processed (e.g., to isolate the carbon produced in the reaction from the hydrogen produced in the reaction).
  • the distribution/collection system 5140 includes a reactant source 5141 that directs a reactant to the first reaction zone 51 1 1 a, and one or more product collectors 5142 (two are shown in Figure 1 1A as a first product collector 5142a and a second product collector 5142b) that collect products from the reactor 51 10.
  • the product collectors 5142a, 5142b can collect products directly from the first reaction zone 51 1 1 a.
  • intermediate products produced at the first reaction zone 51 1 1 a are directed to the second reaction zone 51 1 1 b.
  • the reactant sources 8153 include a methane source 8153a and a carbon dioxide source 8153b.
  • the methane source 8153a is coupled to a first reactant valve 8151 a having a corresponding actuator 8152a
  • the carbon dioxide source 8153b is coupled to a second reactant valve 8151 b having a corresponding actuator 8152b.
  • the reactants pass into the reaction vessel 8101 and are conducted upwardly around the second reaction zone 8120 and the first reaction zone 81 10 as indicated by arrows A.

Abstract

La présente invention se rapporte à des systèmes et à des procédés permettant de collecter, de stocker et de transporter une énergie thermique aqueuse. Selon un mode de réalisation particulier, un film flottant conserve l'énergie solaire dans un volume d'eau situé sous le film. Une série de rideaux suspendus à partir d'une surface inférieure du film délimitent un passage entre la périphérie du film et le centre du film pour diriger l'eau chauffée vers le centre du film. L'eau chauffée circule pour transmettre la chaleur à un réacteur de dissociation et/ou à une substance donneuse. Le donneur est transporté jusqu'au réacteur, puis est dissocié.
