| 20130101356 | Ocean rafts for mining hydrogen - These Ocean rafts for mining hydrogen consist of a variety of structurally connected modules that form seaworthy powered maneuverable floating ocean platforms for an on-board hydrogen mining and storage facility, as well as an oxygen, distillation, and mineral recovery operation. These operations shall be powered by synergistic clean energy systems consisting of: a photogalvanic solar array; wind turbines; perimeter wave action devices; and mechanisms that derive electrical energy from the variable tension on the anchor lines. There may also be a small on-board nuclear reactor to generate continuous additional electricity. Underwater propellers powered by fuelcells, capable of a full 360 degree rotation and located on the corners of the platform, will enable rotation and navigation of the entire assembly. Hydrogen, oxygen, distilled water, and ocean minerals shall be routinely unloaded near a storage facility, before returning to sea for a new cycle of mining; or routinely picked up by specialized ocean tankers. | 04-25-2013 |
