NOVELTY - A light energy conversion system has a light-harvesting station, a storage station and a thermal energy release station. The light-harvesting station comprises a photochemically active organometallic compound. The storage station comprises higher-energy organometallic compound capable of converting to lower-energy photochemically active organometallic compound when exposed to solid-state catalyst. The thermal energy release station comprises solid-state catalyst capable of catalyzing catalytic conversion. The conversion releases 15 kcal/mol or more of thermal energy.    USE - System is used for converting light energy to thermal, mechanical or electrical energy (claimed).    ADVANTAGE - The system effectively enables conversion of solar energy into other forms of energy. The solar energy is stored in form of chemical bond energy for a long period of time.    DETAILED DESCRIPTION - A light energy conversion system has a light-harvesting station, a storage station and a thermal energy release station. The light-harvesting station comprises a photochemically active organometallic compound capable of being converted to a higher-energy organometallic compound when exposed to light. The storage station comprises higher-energy organometallic compound does not capable of converting to lower-energy compounds and capable of converting to lower-energy photochemically active organometallic compound when exposed to solid-state catalyst. The thermal energy release station comprises solid-state catalyst capable of catalyzing the catalytic conversion of the higher-energy organometallic compound to the lower-energy photochemically active organometallic compound. The conversion releases 15 kcal/mol or more of thermal energy. INDEPENDENT CLAIMS are included for the following:    (1) thermal energy release station used in solar energy conversion system;    (2) composition containing photochemically active organometallic compound and/or higher-energy organometallic compound, and catalyst; and    (3) conversion of light energy to other forms of energy.    DESCRIPTION OF DRAWING(S) - The drawing shows the flowchart explaining storage and conversion of solar energy.
