Provided is an undersea tunnel system for reducing typhoon, hurricane, and tornado disasters. The undersea tunnel system for dispersing to weaken or preventing collection of tropical low pressure by reducing typhoon, hurricane, and tornado disasters comprises: an undersea tunnel through which a warm surface current or seawater of a high temperature can pass; a floodgate capable of controlling the entrance and exit of the seawater passing through the undersea tunnel; a first regulator for controlling the opening and closing of the floodgate; at least one water pressure machine (air regulator) for regulating the velocity and water pressure of the seawater passing through the undersea tunnel; and a second regulator for regulating the output of the water pressure machine (air regulator).

An aircraft propulsion system includes a hydrocarbon fuel store, a hydrogen fuel store, an engine system capable of producing thrust by combusting hydrocarbon fuel and/or combusting or oxidising hydrogen fuel, a conveying system to convey hydrocarbon and hydrogen fuel from the fuel stores to the engine system and a control system to control the respective flow rates of the fuel within the conveying system. The control system adapts the fractions of the total fuel energy flow rate to the engine system represented by the hydrocarbon and hydrogen fuel energy flow rates in order to reduce climate warming impact caused by at least one of carbon dioxide, water vapour and condensation trails and/or increase climate cooling impact caused by condensation trails produced by the aircraft propulsion system compared to a dual-fuel propulsion system in which a reserve of hydrocarbon fuel is entirely combusted before any of a reserve of hydrogen fuel.

A method for optimizing plant growth in a hybrid growing environment may implement artificial intelligence to measure and alter plant biometrics. Independent variables may be altered by a control unit by manipulating various control systems within the growing environment. Dependent variables may be measured, and the response of the dependent variables may be recorded in association with the alteration to the independent variables. A historical database may store data regarding the variables and may be referenced and updated by an exemplary embodiment. The control unit may optimize one or more variables or parameters based on a targeted value or outcome. An exemplary hybrid growing environment may include one or more vertical growing phases and a horizontal phase. The phases may implement various watering systems and may be hydroponic, be a complete CEA, use a mixture of natural, artificial, and/or supplemental lighting.
