The present invention concerns a method and an arrangement for dehumidifying and desalting interior air in off-shore installations. A simplified arrangement is presented wherein exterior intake air containing water rich in supersaturated and wet salt particles is pretreated with dry and salt free pretreatment air before entering a dehumidifying and de-salting unit from which the intake air exits as desalted and dehumidified exit air. A part of this desalted and dehumidified exit air is then redirected to the intake air flow path to serve as pretreatment air thereby simplifying construction and enhancing the lifetime of the dehumidifying and desalting unit.

An apparatus that can optimize wind power without compromising solar photovoltaic power collection by doing so and yet provide self-cleaning of the solar photovoltaic panels of the collector. The panels rotate in unison with rotation of the wind turbine airfoils and arranged in a planar region that is substantially transverse to a circumferential region in which the airfoils rotate beneath the solar photovoltaic collector.

An energy unit capable of being configured in a transportation configuration and in an operational configuration. The unit comprises a container having first and second ends opposing a longitudinally-extending central section. In the transportation configuration, the container's central section is positioned generally parallel with a supporting ground surface. In the operational configuration the container is configured to be positioned with the first end on the supporting ground surface such that the second end is set apart in an upward direction from the supporting ground surface. The energy unit additionally comprises a wind turbine for generating electrical energy. In the operational configuration, the wind turbine is configured to be received within the interior space of the container, while in the transportation configuration the wind turbine is configured to extend from the exterior surface of the container.

Systems, methods, and computer readable medium are disclosed for coordinating rotation of adjacent turbines. Coordinating rotation of adjacent turbines includes receiving first rotational orientation information from a first turbine having a first open concave surface and corresponding convex surface; receiving second rotational orientation information from a second turbine having a second open concave surface and corresponding convex surface; receiving fluid flow direction information relative to the first and second turbines; calculating a rotational speed adjustment to cause, at instantaneous times, the first and second open concave and corresponding convex surfaces to be simultaneously transverse to the direction of fluid flow; outputting a control signal embodying the rotational speed adjustment to thereby regulate rotation of the first and/or second turbines such that at the instantaneous times, the first and second open concave and corresponding convex surfaces are transverse to the direction of fluid flow.

A large-scale, modular, wind power generating structure and system involving a toroidal or ovoidal shaped wind amplification structure/module that can be stacked vertically to form a tower that passively accelerates a wind flow that moves around each of the modules due to the Bernoulli Principle. Each amplification level includes a plurality of vertical axis wind turbine and generator assemblies, fairings, and vanes that form a synergistic system wherein the efficiency of the vertical axis turbine and generator assemblies and the amount of energy that can be produced per module are substantially improved compared to the turbine assemblies operating outside the integrated and amplified wind system.

Wind energy assemblies and deployment methods are provided that include a telescoping mast, an energy conversion system, and a carriage assembly. The telescoping mast has a top and a bottom, a mast roller system, and a plurality of mast sections. At least one of the mast sections is an internal mast section, and at least one of the mast sections is an external mast section. The energy conversion system is mounted to the top of the telescoping mast and includes a steering system, a wind instrument mast, a drive assembly, a rotor hub, a disc brake, and a plurality of blades extending from the rotor hub. The carriage assembly supports the telescoping mast. The mast roller system enables the at least one internal mast section to be pulled out from the at least one external mast section, thereby facilitating extension of the telescoping mast. A hydraulic ram assembly may be provided to rotate the telescoping mast to a vertical position.
