We proposed and theoretically analyzed a small distiller using wind energy for maritime lifesaving or small distiller which can be used at local area. The distiller consists of a wind mill and a number of cylindrical partitions in contact with saline-soaked wicks. The shaft energy from the wind mill is transported as the frictional thermal energy of a liquid heat medium to the distilling section, where the energy is recycled to increase the production rate of the distillate. The viscosity coefficient of liquid heat medium and diameter ratio between rotor shaft diameter and inner diameter of heat transfer pipe are designed as the distiller has 3m/s wind cut-in speed at 0℃ liquid heat medium temperature before working. We found that the distiller, which has a 0.6m wind mill rotor diameter, a 5mm diffusion gap and 7 distillation cells, can produce 1.5kg a day with 6m/s wind speed. The amount of fresh water is enough to meet the requirement of one person in one day.
