Description
Wajid Ali Khan, Fawaz Jalal, and Faisal Al Harbi test a solar still in a 2026 study from Bahrain. The island nation leans on energy-hungry desalination while fresh water runs short. A passive single-slope solar still, which uses only sunlight, could serve small needs. The team modeled its output and built a prototype to check the math.
The model predicted just over two liters per square meter per day at about a third thermal efficiency. The prototype matched within about four percent. Water depth, cover angle, wind, and sunlight all shifted output. Three add-ons, including heat recovery and basin fins, could lift output by over forty percent on paper. The authors call for field tests to confirm the gains.
