    Abstract: An improved Ocean Thermal Energy Conversion system (called OTEC) is presented herein by the addition of a closed heat transfer loop. In conventional OTEC, warm surface waters are used to vaporize a working fluid for use in a turbine, and cold waters are then brought up from deep water, typically more than 1000 meters, to condense the working fluid. In simple terms conventional OTEC brings the cooling potential up to the warm surface. The disclosed OTEC system brings the heat down to the deep cold waters by using a separate heat transfer fluid loop. We refer to this as Enhanced OTEC or E-OTEC. A key feature of the process is descending to the depths as a dense fluid and returning to the surface as a much lower density fluid, thereby gaining a gravitational boost in pressure and temperature. This leads to several technological, performance, and economic advantages over prior art.

    Abstract: Surface modification control stations and methods in a globally distributed array for dynamically adjusting the atmospheric, terrestrial and oceanic properties. The control stations modify the humidity, currents, wind flows and heat removal rate of the surface and facilitate cooling and control of large area of global surface temperatures. This global system is made of arrays of multiple sub-systems that monitor climate and act locally on weather with dynamically generated local forcing & perturbations for guiding in a controlled manner aim at long-term modifications. The machineries are part of a large-scale system consisting of an array of many such machines put across the globe at locations called the control stations. These are then used in a coordinated manner to modify large area weather and the global climate as desired. The energy system installed at a control stations, with multiple machines to change the local parameters of the ocean, these stations are powered using renewable energy (RE) sources including Solar, Ocean Currents, Wind, Waves and Batteries to store energy and provide sufficient power and energy as required and available at all hours. This energy is then used to do directed work using special machines, that can be pumps for seawater to move ocean water either amplifying or changing the currents in various locations and at different depths, in addition it will have machineries for changing the vertical depth profile of the ocean of temperature, salinity and currents. Control stations will also directly use devices such as heat pumps to change the temperatures of local water either at surface or at controlled depths, or modify the humidity and salinity to change the atmospheric and oceanic properties as desired. The system will work in a globally coordinated manner applying artificial intelligence and machine learning algorithms to learn from observations to improve the control characteristics and aim to slow down the rise of global surface temperatures. These systems are used to reduce the temperatures of coral reefs, arctic glaciers and south pacific to control the El Nino oscillations.

    Abstract: The present invention relates to an evaporator of a working fluid for an OTEC plant, comprising an evaporator body, a bundle of evaporators extending along the central axis, subject to a pressure drop along this axis and suitable for evaporating the working fluid according to an evaporation profile defined based on this pressure drop and a spraying system comprising a working fluid supply network and a plurality of spray nozzles arranged on the supply network and able to spray the working fluid.
    All of the spray nozzles have substantially the same spray rate and the arrangements of the spray nozzles in relation to the bundle of evaporators are chosen so as to ensure a predetermined spray profile along the central axis in accordance with the evaporation profile.

    Abstract: Systems and methods are described for sequestering carbon stored in organic matter while minimizing the release of carbon dioxide (CO2) and methane (CH4) into the atmosphere, with the carbon (C) being stored as char or coal through the coalification process. Organic matter will be moved to submarine hydrothermal vent fields where the extreme heat in the water will drastically accelerate the degradation of the material and destroy microbes that normally consume the organic material and release the carbon as CO2 or CH4. The oxygen level in the heated water around the vents is extremely low. The water surrounding these vents can reach temperatures of 400° C. (750° F.). Exemplary implementations may include constructing hydrothermal borehole vents to harness the energy continuously released from the Earth's core in the form of volcanic heat.

    Abstract: The present application pertains to novel methods to generate power. In a representative embodiment, power is generated by warming a body of air having a temperature lower than the freezing point of liquid water by contacting the body of air with liquid water. The liquid water has a temperature greater than the freezing point of liquid water. Liquid water freezes thereby generating latent heat from freezing and thereby warming the body of air. The warmed body of air may be passed through an air turbine to generate power. Other methods and systems are described that use similar principles.
