1705 results about "Ocean current" patented technology

An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements.

Submersible electrical power generating plant

A self-supporting, submersible generating plant for producing electricity from ocean currents, consisting of two counter-rotating, rear-facing turbines with a plurality of rotor blades extending radially outward from two separate horizontal axis that convey the kinetic energy from the two side-by-side, counter-rotating turbine rotors through separate gearboxes to separate generators that are housed in two watertight nacelles that are located sufficiently far apart to provide clearance for the turbine rotors. The two generators and their gearboxes serve as ballast and are located far below a streamlined buoyancy tank that extends fore and aft above and between them. A combination of a leverage system and a pressure-controlled system adjusts the hydrodynamic lifting forces to maintain constant depths. There are systems to purge the ballast water to facilitate the recovery of both individual submersible power plants and a group of many submersible power plants.

Deployable submarine-hydroelectric generator for sea currents energy harvesting

Deployable submarine hydroelectric generator for conversion of kinetic energy of deep ocean currents into electricity by having an electric generator mounted in a sealed hydrodynamic, buoyant vessel with tail fins, and connected by a shaft to a rotary turbine blades at the tail end of the submarine vessel, which vessel is anchored at desired depth to the bottom of the ocean by a cable. The drag of the turbine blades causes the vessel to self-steer against the direction of the ocean current. An electric cable is also provided, connecting said electric generator with electric grid on the land. Such generator is out of sight, unlike windmills, and is environmentally friendly to the sea life, due to slow rotating blades. This clean electricity can also be used for production of low cost hydrogen by electrolysis of sea water.

Multi-Megawatt Ocean Current Energy Extraction Device

An underwater apparatus for generating electric power from ocean currents and deep water tides. A submersible platform including two or more power pods, each having a rotor with fixed-pitch blades, with drivetrains housed in pressure vessels that are connected by a transverse structure providing buoyancy, which can be a wing depressor, hydrofoil, truss, or faired tube. The platform is connected to anchors on the seafloor by forward mooring lines and a vertical mooring line that restricts the depth of the device in the water column. The platform operates using passive, rather than active, depth control. The wing depressor, along with rotor drag loads, ensures the platform seeks the desired operational current velocity. The rotors are directly coupled to a hydraulic pump that drives at least one constant-speed hydraulic-motor generator set and enables hydraulic braking. A fluidic bearing decouples non-torque rotor loads to the main shaft driving the hydraulic pumps.

Fluid property regulator

InactiveUS20080277492A1Low average atmospheric temperatureReduce greenhouse gasFog dispersionMachines/enginesAtmospheric airVolumetric Mass Density
A self-sufficient material property profile regulation method and system, for adjusting fluid property profiles such as in an ocean of multiple property layers, is described. Using this Fluid Property Regulator, the property profiles of a non-enclosed material, including property profiles related to material density, chemical characteristics and space-time position, are affected due to motion of the material relative to a body in the flow stream. The state of other matter with which the initial material then makes direct or indirect contact is also affected. For example, in the case of a liquid such as an ocean current, the temperature, salinity, nutrient content and other properties may be destratified (i.e. layers being combined) as the system lifts large quantities of deep water and combines this material with surface water in the downstream far-field region of the system. The resulting regulation of such ocean water property profiles may then also indirectly affect the properties of the atmosphere above the ocean so that the system can be said to affect planetary properties both oceanic and atmospheric. Rather than merely discharging a pumped material, such as cold water that might quickly re-submerge, the system regulates lasting property profiles. The new Fluid Property Regulator system described in this invention regulates material properties to produce desired outcomes such as increased food and energy production as well as to prevent undesirable outcomes such as hurricanes, elevated planetary temperatures, decreased planetary ice sheet size, raised sea level and glacial freshwater incursions that can halt important major currents.

Eolic marine electrical generator geem

In short, the Eolic Marine Electrical Generator "GEEM" is an extraordinary invention used for capturing the huge impulse force of water or wind, to generate mechanical energy and to transform the mechanical energy into electrical energy, clean and ecological, without consuming vital oxygen thanks to the invention of immense split, self-regulating panels, radially fixed in dihedral angle to a rotary central shaft, panels which capture by shock the inexhaustible energy of the wind, the waves or the ocean currents; or fixed on rotary or flying machines of high speed, with panels formed at the same time by oscillating vanes that at a certain time of a turn of 360° will face the natural energy as a single group or panel, capturing therefrom the impulse force and converting it into rotary movement through the central rotary shaft. Said vanes in other rotation, by oscillation, will divide the panel and will align themselves with the natural vector, permitting its free passage, eliminating the turning resistance of the panel against water or wind and generating a constant rotation movement, independent of the direction of water or wind, and then transforming said mechanical energy into electrical energy by existing conventional means. The invention will allow men to renew their resources and to obtain electrical energy from anywhere in the planet such as cities, countryside, deserts, forests, mountains, seas, floating cities or spaces such as the Arctic and the Antarctic, neither polluting the environment, nor depending on costly networks or non-renewable inputs. The invention will also generate electrical energy on fleets, land vehicles or airship without consuming non-renewable fuel or destroying oxygen. Moreover, this invention replaces the internal combustion engines by eolic electrical motors, changing the scenery of the modern world and recovering the ozone lost in the Antarctic. And this invention will also be used when men in future colonize planets, without rivers or seas but with plenty of wind, to generate electrical energy without polluting this new vital space of the human race.
