SPECIFICATION a) This Madson Wind Turbine System (MWTS) Improvement provides for a robust propeller system (Figs 4a, 5a, 6a) having propeller blades (Figs 9g, 10g, 11g) which may be enclosed within inner and outer circular cowlings (Figs 10i, 11 i) in an aerodynamic configuration such that the entire leading edge of each propeller blade, as well as, each entire propeller blade may be feathered to a fully neutral position by a feathering actuator (Figs 10h, 11 h) controlled by a feathering drive (Fig 7e) operated by an elevator on a horizontal fin designed to move up and down in reaction to wind velocity such that a very high wind will adjust all the propeller blades to a fully neutral position (Fig 7). The design is sufficiently robust to resist hurricane and typhoon winds of up to 200mpH or 325kpH (Figs 4, 5, 6). The elevator, feathering device, feathering actuator and propeller blades are connected by tension bars (Figs 7, 7f, 9f, 10f, 11f) so that all the components act together. The cowling also serve to scoop and compress air at the leading edges (Fig 0i) of the propeller blades in order to drive them more effectively, as well as to create a vacuum at the trailing ends (Fig 10i) in order to accelerate the exhaust of air passing thru the propeller blades. b) This MWTS Improvement further provides for built-in derricks at the front top of the turbine nacelle (Fig 711 ), in the middle top of the turbine nacelle (Fig 7I2) and at the rear top of the turbine nacelle (Fig 7I3). This enables the self- erection of the heaviest turbine components during construction and maintenance. With these derricks heavy cranes are not needed at all. The towers may be erected by light cranes including light tower cranes after which the towers, themselves, with their built-in derricks can self-erect the heaviest components; both during construction and during maintenance. c) This MWTS Improvement lowers all heavy components of the wind turbines, aside from the propeller, vertical fin and horizontal fin, to the base of each wind turbine: as in the case of each air turbine compressor - estimated to weigh about 15MT (Figs 13, 14, 15, 16) or to the base of a central plant: as in the case of the heat exchanger Cooling Tubes (Fig 12). d) This MWTS Improvement simplifies and improves the cooling of hot compressed air or gas so that it may be more effectively compressed to high pressure than is, otherwise, possible with very hot gas (Fig 12) and heating cold decompressed gas for increased energy and expanded volume to produce more electricity (Fig 12) than would be possible with cold constricted air or gas by conveying all the hot gas from Stage 5 of the staged compression system in the MWTS Wind Turbines to Ring 1 of the staged decompression in the MWTS Reserve Tanks (Fig 12), thereby, performing all the cooling of hot air or gas and the heating of cold air or gas in 1 place, which is in Ring 1 of the MWTS Reserve Tanks (Fig 12). This reduces the positions where heat exchange takes place from 50 heat exchangers in remote locations (for a 500mW Power Plant, as in the previous invention) to 1 central location (in this invention), thereby reducing the complexity of the heat exchangers from 50 small units to 1 large unit (Fig 12) and greatly reducing the piping needed to convey cold air from Ring 2 of the Reserve Tanks to 50 remote heat exchangers in the wind turbines at Stages 6 to 10 inclusive plus the piping needed to return the heated air or gas from those 50 remote locations to Ring 1 of the Reserve Tanks (as in the previous design) to 1 location in Ring 1 of the Reserved Tanks (as in this invention), (Fig 12) from which the air or gas is delivered to the air turbine engines for electricity generation. e) This MWTS Improvement provides open and closed systems (Fig 13 and Fig 14, respectively). With an open system in which ambient air is taken in at the Stage 1 Wind Turbines before being conveyed to subsequent Wind Turbines for higher staged compression. With the closed system, the air or gas is recirculated thru the system also starting at Stage 1 and circulated thru the entire system. This requires an extra duct to convey the air or gas from the Air turbine engines to the Stage 1 Wind Turbines (Fig 12). The Closed system allows total control of the quality of the air or gas drive medium for dust, salt, moisture or other impurities. f) This MWTS Improvement provides 3-axis couplings (Figs 17, 18, 19, 20) with Swivel Joints (Fig 21 ) to convey air or gas for the flexible connection of ducts and pipes to convey air or gas from Wind Turbine to Wind Turbine for staged compression, for conveying cooling or heating air or gas between the Reserve Tanks and the Wind Turbines or for conveying recirculated air or gas from the Air Turbine Engines to Stage 1 of the Wind Turbines. g) This MWTS Improvement provides for Multiplier Gears (Figs 8m, 13m, 14m, 15m, 16m)to accelerate rotational speeds from about 20 RPM at the Propeller (Fig 7) to about 540 RPM (Figs 7, 8) at the input shaft of the Gearbox, after which rotation is increased to about 3000 RPM within the gearbox to eliminate vibration and for efficient driving of the air or gas Turbine Compressors.

This MWTS makes the wind turbines entirely self-directing and self- regulating mechanically and without the need for any electrical or electronic components so that the MWTS Wind Turbine automatically points into the wind and automatically adjusts propeller pitch without the need for human or computer intervention (Figs 1 , 2, 3, 4, 5, 6, 7, 9, 9f, 9g, 10f, 10g, 10h, 11f, 11g, 11 h). This is achieved by means of a vertical fin which keeps the turbine automatically pointed into the wind (Figs 1j, 2j, 3], 4j, 5j, 6j), and a horizontal fin elevator which automatically adjusts the pitch of the sails in proportion to wind speed (Fig 7).

The vertical fin and horizontal fin also streamline the air flow after the wind passes through the sails.

In this MWTS, the wind turbines have been simplified to the maximum extent. Each wind turbine contains only an air turbine compressor at its base (to eliminate high loads), which is driven by the propellers (Figs 1a, 2a) thru a drive train (Figs 7, 8), which includes multiplier gears (Fig 8m) and a simplified gearbox (Fig 8n), which increases the revolutions of a drive shaft sufficiently for efficient compression by an air turbine compressor. The air turbine compressor is designed to operate efficiently over a wide range of revolution speeds; therefore, always operating efficiently.

For further simplification and efficiency, all heat recovery takes place in a central location in the outer Ring 1 of the central Reserve Storage Tank (Fig 12). Which has the dual purpose of cooling the overheated air in Stage 5 of the compression, thereby making compression to higher levels more efficient, as well as energizing and expanding the volume of the air in Ring 1 (Fig 12) which is delivered to the Air Turbine Engines, and in this way, increasing electricity generation.

The MWTS makes wind energy storable and dispatchable, making possible the supply of base load and peak load requirements, and overcoming the intermittence of wind, which has been the main problem concerning the generation of electricity by wind power.
