Water harvested from the air combined with solar power, shade and light providing system: Conception of water-saving irrigation

In China, agriculture accounts for the largest proportion of water consumption. Analyzing the present water-saving irrigation situation, we propose to build a combined system. First, the system could use the farmland solar energy resource, transfer it into electricity, which will cover the wants of agricultural production and farmers’ daily lives. Second, according to the crops’ wants of sunlight, the system could adjust the light's strength and lasting time by providing shade and artificial light. Third, the system could harvest water from the air with bionic material structure, which will use the water resource circularly result in the improvement of water utilization efficiency.
