摘要： A hydroelectric power generation system includes a turbine assembly configured to be submerged under water and adapted to reciprocate in a vertical direction. The turbine assembly includes a turbine impeller having a plurality of blades configured to rotate about a central axis, and a turbine casing arranged surrounding the turbine impeller. The hydroelectric power generation system further includes a generator operatively coupled to the turbine impeller and a prime mover operatively coupling the turbine impeller to the generator. The turbine assembly is configured to slide relative to the prime mover in the vertical direction. The system further includes a displacement mechanism to move the turbine assembly in the vertical direction between a first position and a second position. The turbine impeller rotates in response to the vertical movement of the turbine inside the water, causing the rotation of the prime mover to operate the generator to generate electricity.

摘要： A water-driven turbine has an elongated endless conveyor with down and up streaming straightaways connected by travel-reversing turns. Paddles mounted on the conveyor present high resistance to waterflow on the downstream straightaway and low resistance to waterflow or the atmosphere on the upstream straightaway, the differential allowing the flow of water to continuously drive the conveyor which is connected to a power take-off shaft facilitating connection to a variety of energy-harnessing systems. The turbine can be towed, self-driven or mooring line manipulated to a flow site and is operable in unidirectional flows such as rivers and reversing flows such as tides at depths from surface to bottom. The paddles can be mounted or changed on shore, at the flow site and anywhere in between. The turbine is efficient in low and high velocity water flow, not easily damaged by floating debris, cavitation free and fish, mammal and environmentally friendly.

摘要： 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.
