TL;DR: The desalination of sea water for the prodn. of drinking water is achieved by solar energy which heats the warm sea surface water through condensing lenses or convex mirrors.
Abstract: The desalination of sea water for the prodn. of drinking water is achieved by solar energy which heats the warm sea surface water through condensing lenses or convex mirrors. Cold sea bottom water is pumped up and used to condense the vapours produced. A part of the vapour is branched off for a turbine to produce the required power for pumps. The hot air, used in counterflow to remove the residual water from the brine is also produced by solar energy.

TL;DR: For large-scale application of geothermal energy from steam and hot water, effective heat exchange equipment is needed to overcome the fouling and corrosion from such pollutants as silica, lime, CO/sub 2/, and sulfurous compounds that impede efficient heat transfer as mentioned in this paper.
Abstract: For large-scale application of geothermal energy from steam and hot water, effective heat exchange equipment is needed to overcome the fouling and corrosion from such pollutants as silica, lime, CO/sub 2/, and sulfurous compounds that impede efficient heat transfer. The problems are discussed in regard to both binary cycle units and refrigeration systems. (LBS)

TL;DR: In this paper, a distillation system is proposed for sea water desalination, which gives high performance ratios at low flashing ranges, which leads to a substantial saving in the distillation plants running costs.
Abstract: Despite the fact that the world's need for fresh water is becoming more urgent, the ability to desalinate economically on a large scale still remains a goal rather than a reality. Distillation systems are by far the most widely employed systems for sea water desalination. However, the relatively high costs of these systems' products limits their competence with natural water resources, particularly for agricultural use. In this paper a distillation system is proposed. The system gives high performance ratios at low flashing ranges, which leads to a substantial saving in the distillation plants running costs. The analyses showed that the system has big thermodynamic potentialities.
