PURPOSE:To improve the efficiency of utilization of sunlight by a method wherein in the titled device in which optical energy such as sunlight is released as thermal energy in time of need, a transfer pipe is connected to a sealed vessel through which an optical energy storing chemical compound circulates, so that the optical energy is eleased into the sealed vessel. CONSTITUTION:In case the energy accumulating device is used, a light collecting unit 24 of a light collecting device 12 is moved to follow the sun and the sunlight converged by converging lenses 28 is introduced into the sealed vessel 24 arranged in an underground room 43 through a bundle of optical fiber cables 32 and the transfer pipe 38. In this case, the sealed vessel 44 includes therein an N-substance (a chemical compound capable of being highly distorted) transferred from an N-substance storage vessel 66 through the operation of a pump 68 and such N-substance is coverted into a Q-substance (a highly distortional chemical compound) as a result of its optical reactions against the sunlight from the transfer pipe 38. The Q-substance is then stored in a storage vessel 56 through a pipe 54 and after that, it is transferred to a catalyst device 62 within a hot water storage tank 60 by means of a pump 58. Thus, the water in the tank 60 is heated by the thermal reactions of the Q-substance against the catalyst and the Q-substance itself is converted into the N-substance so as to be returned to the N-substance storage vessel 66. |
