A material (such as potassium hydroxide or ammonia) capable of reacting with ambient carbon dioxide to produce fertilizer is placed in the path of ambient air movement. Desirably the material is associated with a fabric which in turn is associated with a vane of a vertical axis wind turbine, the turbine performing useful work as well as supporting the material which produces a fertilizer. A misting system controlled by a controller may automatically apply a water mist to the material if the humidity is below a predetermined level. The fabric with produced nitrogen and/or potassium fertilizer may be placed directly into contact with soil, or shredded first, or burned to produce energy and an ash (and the ash applied to the soil). The wind turbine may have a convenient, versatile mounting system with three adjustable legs supporting a central component, and the spokes of the wind turbine may be slotted for easy assembly with vanes.

In an electro-optical device, a first polarizing element, a first phase difference element, a transmissive liquid crystal panel, a second phase difference element, and a second polarizing element are sequentially arranged. Here, when a phase difference of the first phase difference element and the second phase difference element is λ/4, an influence of orientation disorder of liquid crystal molecules can be alleviated, but a contrast ratio is reduced. Therefore, when a wavelength of incident light is λ, a phase difference R of the first phase difference element and the second phase difference element satisfies the following condition that 0<R<λ/4, preferably λ/12<R<λ/6. For example, it is assumed that the phase difference R is λ/8.
