<p>A greenhouse has an irrigation system which comprises collecting condensation from crops arising out of evapotranspiration. The system may also capture dew. The greenhouse may have a roofAwhich causes humid air to condense, the water being collected by internal guttersBat the sides of the roof. The inner side of the roof may have a super hydrophobic surface or capillary fluting to the underside to encourage condensation. The sidesCof the greenhouse may capture dew or fog capture on fine mesh materials, the liquid being collected in secondary guttersBat the base of the mesh. The mesh may be height adjustable. The water collected may be filtered and stored in a storage tankJ. The greenhouse may have a translucent thin film photovoltaic power generation unit in the roof.</p> |
