TECHNOLOGY FOCUS - AGRICULTURE - Preferred Method: The fertilizer produced, is potassium carbonate, potassium bicarbonate, and/or ammonium bicarbonate, and is ultimately put into contact with soil to fertilize plants. The method involves placing the fabric in the path of ambient air movement. The method further involves placing the fabric and material on a moving portion of a wind turbine; and where the wind turbine provides mechanical force; and further involves utilizing the mechanical force to perform useful work. The method further involves applying a mist containing water to the material at spaced time intervals if the humidity and/or related conditions are insufficient to provide acceptable reaction conditions, using at least one nozzle stationarily, with respect to wind turbine rotation, positioned below the wind turbine and controlled by a controller. The method involves, after carbon dioxide removal to produce fertilizer, putting the fabric into direct contact with soil. The method involves, after carbon dioxide removal to produce fertilizer, shredding the fabric and then putting the fabric into contact with soil. After carbon dioxide removal to produce fertilizer, the method involves burning the fabric to produce useful energy and an ash, and applying the resulting ash to soil. The method further involves applying calcium and/or magnesium to the soil to which the fertilizer is applied; and where the material comprises potassium hydroxide, potassium superoxide, potassium carbonate, and/or ammonia. The material is applied to a wind-engaging surface of a wind turbine; and the wind turbine provides mechanical force; and further involves utilizing the mechanical force to perform useful work. The method further involves applying a mist containing water to the material if the ambient humidity is less than 40-50%. The method involves placing at least one of a potassium containing compound and a nitrogen containing compound, in a form capable of reacting with carbon dioxide to produce a second potassium or nitrogen compound, in the path of movement of ambient air; and then after carbon dioxide removal from the ambient air, regenerating at least one of a potassium containing compound and a nitrogen containing compound from the second potassium or nitrogen containing compound; and where the material capable of reacting with carbon dioxide is associated, with a fabric; and further involves placing the fabric and material on a moving portion of a wind turbine; and where the wind turbine provides mechanical force; and further involves utilizing the mechanical force to perform useful work. Preferred Components: The material comprises a potassium and/or nitrogen containing compound that will ultimately react with ambient carbon dioxide. The material capable of reacting with carbon dioxide is associated with a fabric.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Apparatus: Preferred Components: The combination further comprises an ambient humidity and/or moisture sensor; the sensor operatively connected to the controller to control the nozzle to apply a mist to set the ambient humidity and/or moisture drop below a predetermined level. The nozzle is movable; and further comprises an actuator controlled by the controller for moving the at least one nozzle to position it to direct water mist in varying directions; and further comprises a wind speed sensor. The wind speed sensor is operatively connected to the controller to retard or terminate water mist application if the sensed wind speed is greater or lesser than a predetermined value. The rotor is a two or three vane Savonius rotor; and where all the support legs are telescoping and have polygonal cross-section; and where each telescoping leg includes tubular main portion and an adjustable telescoping portion, with a quick connect/disconnect coupling between them; and further comprises a cross support between each leg and the central component; and where each of the feet has at least two openings in it for receipt of anchoring devices; and where each of the feet is mounted for pivotal movement about a generally horizontal axis with respect to a free end of a leg.
