Fabrication and Testing of a Pyramid-Shaped Solar Still with Fins.

About 40% of the world's population suffer from lack of potable water. The paper attempts to fabricate and test a pyramid-shaped solar still having fins. The conventional solar still serves as the baseline, while the finned design incorporates enhanced heat transfer surfaces to improve productivity. Experiments were conducted during three days in the month of March, and the average results are presented. The higher absorber plate, glass plate and water temperatures were recorded between 12 noon and 1 p.m. in the pyramid solar still having fins. The pyramid-shaped solar still model embraces 3 liters of potable water during the day superior to the conventional still. [ABSTRACT FROM AUTHOR]
