Application of Exergy for Research on Increasing the Usefulness of Solar Radiation by Dispersing It into Monochromatic Beams

Energy determines the ability of matter to work. However, in given environment, real usefulness perform work is determined by exergy. This study covers not only solar, but also any monochromatic thermal radiation. The value such radiation was its exergy and ratio exergy-to-energy. A novelty this demonstrate means that polychromatic can be increased dispersion effect greater, lower temperature Analogies exergetic gas separation have been indicated. increase process interpreted a cylinder-piston system explains with influence environmental concept quasi-monochromatic cumulated introduced into considerations change energetic, entropic components beams analyzed.
