Dear Connectors, does anybody have specific information about systems, which can store thermal energy in forms of either chemical or crystal (structure) energy ? I have read about storing energy in a sulfuric acid - water system based on the hydratation enthalpy of sulfuric acid. Also systems like sodium sulfate / Water are known and -i guess- used in a BMW to heat the engine before starting. I would like to gain some technical information about that. (is it patented ?-- sure ! :-( ) They are latent energy collectors Any suggestion of systems that may work well or systems that posess lots of usable enthalpy resources are welcome. (cheap, many cycles, fast and reversible reaction, stable on room temperature) WHY? There is a close relation between developing high efficent solar systems and storing the energy in an appropriate collector. If one could find well working (many cycles) thermal stores, it could be possible to conserve energy for a long time or even from the summer into the winter. Since photovoltaic is still too expensive and needs immense investment for developing and research, this is an approach which makes sense :). I read about groups doing research on that subject. Who? Where? What? sY Claus ----------------------------------------------------------------------- Claus Fuxen; Friedenstra�e 25, 42929 Wermelskirchen +49 2196-731817 ----------------------------------------------------------------------- ## CrossPoint v3.11 ##
