Design of a Dew collector Greenhouse

A non-profit organization calledRoots Up has designed a greenhouse that collects moisture from the air, which then is used to water the plants.

This greenhouse has multifunctional purpose: grow food and produce water.

This new design can help farmers in areas where the lack of proper temperature and rainfall make it difficult to grow crops.

Inside, the hot air is trapped so the temperature in the greenhouse keeps rising throughout the day.

The heat causes water to evaporate, creating air humidity making the greenhouse atmosphere better for plants’ growth as well as maximizing the dew harvest.

When the surface temperature drops at evening until morning, the farmer pulls out the rope to open the top of the greenhouse allowing it to cool, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface of the bio-plastic sheet falling into the water tank container.

This system allows farmers to harvest water used as safe drinking water and irrigation.

Roots Up plans to launch the project in areas of Ethiopia, where droughts are common and farming is difficult.
