| Abstract: | Studies on simultaneous utilization of solar stills as a thermo-concentration cell and as a distillation system have been reported. Cell characteristics have been studied. The electrical energy has been found to increase both with the increase in concentration of sodium chloride (salinity) and the temperature of the saline water. This two way utilization of solar stills has an added advantage that overall utilization efficiency of solar energy is increased against a nominal additional input. For application in rural areas where water needs treatment, (distillation) this extra electrical energy may make it more attractive. The possibility of application of such systems in the industrial sector has also been mentioned. |
