Disclosed is wind flow operated ventilation and energy harnessing device, comprising an L-shaped flow pipe (101/201) with one arm sweeping horizontally while the other rotatable on a stationary vertical pipe (102/202) connected with the space being ventilated. The open end of the horizontal portion is flared into collar (106) or bell-shaped mouth (206) forming evacuating or pressurizing flow pipe respectively. The direction changers (108/208) are used to maintain the back of collar (107) of flared portion (106) or open end (207) of bell-shaped mouth (206) facing upstream wind. The wind on striking the back of collar (107) or the open end (207) of bell-shaped mouth (206) creates evacuation or pressurization effect respectively for ventilation. A wind turbine fitted inside stationary vertical pipe harnesses energy.

Devices, systems, and methods disclosed for generating embedded clean electrical energy. Particular aspects of the invention disclosed for design and integration of a micro wind generator array and a solar panel to form a micro-embedded electrical energy system. The embedded electrical energy system facilitates to produce more watts per hour in a most efficient way per square meter.

A method and system for generating electrical energy from wind are described. In an example, a method includes capturing wind in an intake on an exterior surface of a structure. The method also includes directing, via a duct, the wind from the intake to a centrifugal fan and, while directing the wind from the intake to the centrifugal fan, compressing and accelerating the wind in the duct. The method further includes receiving, in the centrifugal fan, the wind from the duct and rotating, via the received wind, a fan blade assembly in the centrifugal fan. The method still further includes generating electrical energy, via a generator, based on the rotation of the fan blade assembly.

An energy-supply rotary inertia driver system for an offshore platform includes an annular fixed plate, an active control module, a wind power generation module and a solar power generation module. The system can monitor a motion state of the offshore platform in real time, and can generate a force through the active control module if necessary to apply a force torque of the offshore platform to further achieve the vibration suppression. Moreover, when the offshore platform is under normal operation, the system can act as an energy supply device via wind and solar power generation to feed electric energy to the active control module and other electrical equipment on the offshore platform when needed.
