    Abstract: Comparison of Comparison of Solar Power System (CSP) power plants will be introduced and discussed; Solar Tower (ST) plants and Parabolic Trough (PT) plants are subjects of this comparison. The comparison will be made possibly analytical or quantitatively instead of qualitatively. Examples will be presented and explained in detail. The main issues ... Show More

    Abstract: Phase-Change Materials (PCMs) are substances with a high heat of fusion that melt and solidifyat a certain temperature range. Theyare capable of storing and releasing large amounts of energy and have a high capacity of storing heat. PCMs preventenergy loss during material changes from solid to liquid or liquid to solid. They have several advantages... Show More
