A support-type display device (100) of the present invention comprises: a fixing member (110) which is fixed to a support (200); a display panel (120) which is fixed to one side of the fixing member (110), and has a flexible form that can be rolled and unrolled; and shape maintenance means (130) which are respectively installed along upper and lower parts of the display panel (120), and roll the display panel (120) or unroll in the shape of a flat board to maintain the rolled or unrolled state if an external force is applied. The present invention is installed on an outdoor support and is used for advertising and/or prevention, wherein a flexible display panel which can be rolled and unrolled is used such that the display panel is unrolled only when necessary, whereby the invention can be used for advertising and/or prevention.

A wind turbine ID marker arrangement to enable a wind turbine installation to be identified from the air, the ID marker arrangement comprising a display surface to which a pattern of tiles are removably attached.

A kit for securing advertising space to a horizontal wind turbine at a blade height of the horizontal wind turbine, a horizontal wind turbine including the kit, and methods of making and using the same are disclosed. The horizontal wind turbine has blades on a blade side of the turbine, a non-blade side opposite the blade side of the turbine, a tower and a nacelle capable of turning during normal function. The kit comprises (i) an advertisement and/or advertising space and (ii) a structure that facilitates the turning of a base of the advertisement and/or advertising space to mirror the nacelle. The advertisement and/or advertising space is on the non-blade side of the horizontal wind turbine. The base of the advertisement and/or the advertising space is joined, connected or affixed to the tower and/or the nacelle and can store a plurality of ads in the housing.

A wind turbine is disclosed. The wind turbine includes comprising an inflatable portion comprising one or more blades and a device for rotatably driving the inflatable portion at a predetermined rate for a predetermined time.

An advertising board-type sail-type rail-type pneumatic device comprises four portions: the first portion is a driving body portion including blades (1) and fixed seats (5); the second portion is a control portion including angle locks (6), bearings (3), one-way gears (4), one-way guide teeth (7), synchronous rods (8) and synchronous gears (9); the third portion is a transmission portion including chains (12) and rolling wheels (13); the fourth portion is a supporting portion including rails (11), synchronous rod brackets (10) and supporting columns (14). The pneumatic device has the function of outdoor advertising board and wind power generation, so that it can both supply daily power to buildings and produce advertising income. The components of blades (1), fixed seats (5), rails (11), synchronous devices, chains (12), angle locks (6), one-way guide teeth (7) and the like of the pneumatic device are also disclosed.

A screened wind power generation system for generating power in locations where the sight of wind turbines is undesirable or where advertising space can be utilized. The system uses a screen to cover wind turbines with a mesh size and other characteristics that are appropriate for allowing sufficient wind to pass through to wind turbines. The mesh can be coated or imprinted with surface indicia that constitute advertising or create an appearance that blends with surroundings better than an unscreened wind power generation system. The depth of the screen can vary to better enable muffling of wind turbine noise. The screen cross-section can have an aerodynamic shape to facilitate wind flow through the screen.

A display which can be mounted on the outside of a vehicle includes a generator to generate electricity to power accessories such as a light for illuminating the display. The display may comprise a windsock which is mounted on a support ring surrounding a central hub in which the turbine mounted. The turbine includes an impeller extending on an inlet end of the central hub and a light source electrically connected to the generator and mounted on the central hub and projecting in an opposite direction from the impeller. The windsock is mounted on the support ring in surrounding relationship to the light source. The vehicle mounted wind turbine may power other electronic devices or accessories.

A wind generator system with a plurality of lightweight, surface area adjustable airfoil/sail blades. Each blade is triangular or wedge shape with a narrow inner edge and a wide outer edge. Each blade includes an inner frame connected to a rigid mast that extends radially from a hub assembly. Each blade includes a curved outer skin layer that extends over the inner frame and configured into air foil shape with a large curved leading edge and a thin trailing edge. The outer skin layer is secured along its leading edge and removeably attached along its trailing edge to the inner frame. Advertising is printed on the outer skin of at least one blade that is visible. Coupled to the outer skin layer is a first linear actuator that when activated, causes the outer skin layer to fold or unfold thereby changing the blade's surface area. The internal frame may include a second linear actuator and a telescopic mast over which the blade slides to increase or decrease the sweep area of the blades. Wind or electrical sensors are coupled to the mast and the retractable cable to automatically control the sweep area and the surface areas.

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.

A wind turbine is disclosed. The wind turbine includes comprising an inflatable portion comprising one or more blades and a device for rotatably driving the inflatable portion at a predetermined rate for a predetermined time.
