Enhancement of distillate output of double basin solar still with vacuum tubes

Hitesh N PANCHAL, P K SHAH

Frontiers in Energy 2014, Volume 8, Issue 1,   Pages 101-109 doi: 10.1007/s11708-014-0299-5

Abstract: condensation is lost to the atmosphere; hence it is not utilized to increase distillate output of single basin solarThe performance of the double basin solar still was also increased by attaching vacuum tubes to the lowerThis paper proposed a novel approach to increase the distillate output of the double basin solar stillThe integration of vacuum tubes with solar still greatly increases the distillate output of the solarstill by providing hot water at the lower basin.
