I recently received this video link and information from Professor K.K. Sharma [firstname.lastname@example.org].
After watching your website/blog on water issues, I am happy to note that you are generating awareness about importance of water on earth. In order to save water in the laboratories and industries during distillation process where water is used in the condenser unit for cooling purpose and is left in the drain pipe as a waste, I have devised a simple technique for which a video is available for your view and comments on the following link.
The technique uses water collected from the out let of the condenser tube in an earthen pot. From this pot, water is pumped up to supply tank of condenser unit with the help of a small submersible pump. Water is recycled again and again in the cooling process of condenser tube. This way one can save gallons of water during distillation.
