1. A solar collector comprising fresh water channels containing fresh water adapted to be heated by solar energy, a heat exchanger connected to said fresh water channels and to a source of saline water and having therein fresh water and saline water spaces and where heat is transferred from heated fresh water to saline water, at least one distillation casing having an intermediate wall means therein dividing the interior of the casing into a fresh water region and a saline water region with the saline water region being connected to the saline water space and the fresh water region being connected to the fresh water space, said heat exchanger being positioned between said fresh water channels and said distillation casing with respect to the flow of fresh water through said solar collector and such that said heat exchanger is directly upstream of said distillation casing and directly downstream of said fresh water channels, means for spraying heated saline water from said saline water space into the saline water region where it is cooled to form a vapor and a saline water concentrate, means for spraying fresh water from said fresh water space into the fresh water region to condense said vapor to form additional fresh water and wherein said saline water transfers heat to said fresh water, saline water removal means for removing cooled saline water concentrate from said saline water region and fresh water removal means for removing heated fresh water from said fresh water region.
