NOVELTY - A polycondensation light transmission device (1) comprises light collecting device, non-restricted light transmission channel (3), container (4), optical medium, titanium dioxide light transmission channel (2), light heat transfer device and storage device. The container comprises domestic garbage and plant fermentation solid-state material. The resulting solid materials after fermentation and decomposition is added to bamboo and wood charcoal to form solid-state fermentation product attached to bamboo or charcoal surface forming green fertilizer particles.    USE - As a polycondensation light transmission device for producing green fertilizer (claimed).    ADVANTAGE - Using the device, light energy is converted to heat energy.    DETAILED DESCRIPTION - A polycondensation light transmission device comprises light collecting device, light transmission device, container, optical medium, titanium dioxide light transmission device, light heat transfer device and storage device. The container comprises domestic garbage and plant fermentation solid-state material that are decomposed by exciting water molecule present in the container to form free anion. The resulting solid materials after fermentation and decomposition is added to bamboo and wood charcoal to form solid-state fermentation product attached to the bamboo or charcoal surface forming green fertilizer particles. The light transmission device having main transmission channel is divided into branch light transmission channels, where a switch control line is provided on light transmission channel for light beam to enter into light transmission channel in the light transmission device. The light collecting device allows light to enter through polycondensation functional unit into light transmission device. The light shunting switch is under the control of the light. The light enters the branch of main light transmission channel, where the branch of transmission channel allows transmission of light to the terminal. In branch transmission channel, light is converted to heat energy, where the heat energy is divided into two types, the first one is direct heating and the second one is the redundant heat energy. The light energy is converted to heat energy and stored using storage method without sunlight. The light enters from polycondensation functional unit into light transmission device for transmitting the light from light collecting device. The light energy is converted to heat energy to heat the device in a sealed container.
