Can you harvest water from snow using a solar still setup?

Building a Solar Still for Snow Harvesting

To construct a solar still for snow harvesting, you’ll need a shallow hole, a container, a shovel, and a clear plastic sheet. Dig a hole about 1-2 feet deep, depending on the snow depth, and place a container in the center. This will serve as the collection point for the melted water.

Creating a Solar Still Condensation Chamber

Place a clear plastic sheet over the hole, weighing it down with rocks or logs to ensure it’s in contact with the snow. This will create a condensation chamber where the snow will melt and evaporate, producing water vapor. The plastic sheet should be large enough to cover the entire hole and extend several inches beyond the edges.

Optimizing Your Solar Still for Snow Harvesting

To optimize your solar still for snow harvesting, ensure the plastic sheet is facing south to maximize sunlight exposure. You can also add a layer of insulating material, such as straw or grass, around the container to reduce heat loss and improve condensation. As the water vapor condenses on the underside of the plastic sheet, it will drip into the collection container. With proper setup and maintenance, you can collect up to 1-2 liters of water per hour using this method.
