Abstract
The invention discloses the design of an improved household solar still with enhanced output and high recovery. The output and recovery are enhanced by (i) aligning the top glass and basin so as to maximize the input solar radiation, (ii) using North-South reflectors in V trough configuration to further raise the incident radiation, (iii) employing metallic condensers on sides to maximize condensation efficiency, (iv) using suitably heated and cooled saline water by taking advantage of ambient temperature differential during a day and using such water as feed water and condenser water respectively. Use of detachable top glass assembly and teflon cork at the bottom allows for easy cleaning of the interior of the still and discharge of concentrate, respectively. The still is also demonstrated to be useful for other applications where, besides producing distilled water, the concentrate is a more value added product than the feed.
