A basin type solar still with internal and external reflectors was constructed and then examined in outdoor experiments in winter in Kurume, Japan. The external reflector was inclined slightly forward to make the reflected sunrays hit the basin liner of the still effectively. The daily productivity of a basin type still can be increased about 70% to 100% with a very simple modification using internal...
A vertical multiple-effect diffusion solar still, consisting of a glass cover and a series of closely spaced vertical and parallel partitions in contact with saline-soaked wicks, coupled with a flat plate reflector was constructed and examined in outdoor experiments at Fukuoka, Japan. The vertical partitions make it possible to reduce the diffusion gaps between partitions to increase distillate productivity...
