This greenhouse has multifunctional purpose: grow food and produce water. 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 maximising 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 bioplastic sheet falling into the water tank container.
This system allows farmers to harvest water used as safe drinking water and irrigation.
