Using Transpiration Bags in Combination With Solar Still Techniques?

Designing the System

To integrate transpiration bags with solar stills, design a system that captures condensation from the transpiration bags and directs it into the solar still. Typically, a clear plastic sheet or a tarp is used as the transpiration bag, covering a plant with its roots in a pot. The bag is weighed down and sealed to prevent water loss. A hose or a tube is connected to the bottom of the bag, allowing the collected water to flow into the solar still.

Building the Solar Still

Build the solar still by creating a shallow pit or a depression in the ground, about 1-2 feet in diameter. Line the pit with a clear plastic sheet, securing it with rocks or sandbags. Place a smaller container or a bowl in the center of the pit, where the collected water from the transpiration bag will be directed. Cover the plastic sheet with a clear tarp or a plastic sheet, weighing it down with rocks to ensure the pit is sealed.

Operating the System

When the sun is out, the transpiration bag warms up, causing the water vapor to condense on the inside of the clear plastic sheet. As the water vapor condenses, it drips into the hose or tube connected to the bottom of the bag, flowing into the solar still. The water collected in the solar still is then siphoned off into a container for drinking. This system can provide up to 2 liters of water per day, depending on the number of transpiration bags used and the amount of sunlight received.
