A hydroelectric plant has concentric inner and outer pipes, an air flow channel allowing air flow between these pipes, and floodgate pipes with water flow channels where the water flow is allowed through the inner pipe, an air supply block with a multitude of air inlet vents-which supply air to the mentioned air flow channel and a multitude of water impact paddles upon which the water flowing out of the floodgate pipes via the air supply is impacted.

Systems and methods are presented for deploying and using a floating platform using articulated spar legs used as a type of hull, each of the spar legs attached to the floating platform by an articulated connection. Each of the articulated spar legs being moveable from a horizontal to a vertical position, horizontal for transport and vertical for deployment of the floating platform. The articulated spar legs serve to support the floating position of the floating platform. The articulated spar legs are moved from horizontal to vertical position by controlling ballast imposed upon or within spar legs. Each of the articulated spar legs are moveable from a vertical to a horizontal position with a ballast changing method. Systems and methods are presented for extracting natural renewable energy from the environment surrounding the floating platform with energy capture devices modularly affixed to the platform and energy capture devices incorporated into the articulated spar legs.

Fuel mixed in water is combusted in a reactor having an internal operating pressure and temperature greater than 3200 psi and greater than 374 C., where the combustion of the fuel is exothermic. Air and fuel are pressurized for introduction into the reactor to a pressure greater than the internal operating pressure using energy generated from the combustion of the fuel, and the pressurized air and the pressurized fuel are injected into the reactor. Pressurized water from the reactor is injected into a drive water column that is partially filled with water to increase a pressure of the drive water column, and water at a temperature less than 100 C. is injected into the reactor to replace water from the reactor that is injected into the drive water column. Pressurized water from the drive water column is used to drive a hydroelectric drive system to produce electrical power.

The invention provides a method for computational fluid dynamics and apparatuses making enable an efficient implementation and use of an enhanced jet-effect, either the Coanda-jet-effect, the hydrophobic jet-effect, or the waving-jet-effect, triggered by specifically shaped corpuses and tunnels. The method is based on the approaches of the kinetic theory of matter providing generalized equations of fluid motion and is generalized and translated into terms of electromagnetism. The method is applicable for slow-flowing as well as fast-flowing real compressible-extendable generalized fluids and enables optimal design of convergent-divergent nozzles, providing for the most efficient jet-thrust. The method can be applied to airfoil shape optimization for bodies flying separately and in a multi-stage cascaded sequence. The method enables apparatuses for electricity harvesting from the fluid heat-energy, providing a positive net-efficiency. The method enables generators for practical-expedient power harvesting using constructive interference of waves due to the waving jet-effect.
