Research Abstract	This apparatus condensed the solar light to the evaporating container with the parabola reflecting plate that was able to pursue the solar light, and achieved the desalinization by a highly effective simple distillation method to spray the fog and microscopic a drop of water to the evaporating container inwall and to vaporize instantaneously. A microscopic drop of water was achieved by introducing seawater into the rotating disk with which the slit was formed. Moreover, the temperature radiation loss by the black body emission occurs from the heated evaporating container. The protecting selective absorption material of the temperature radiation loss was introduced, and the desalinization efficiency 40% was achieved.
