Summary: Most electricity is currently generated from polluting hydrocarbons, causing environmental damage and global warming. This leads to an increase in disasters like floods, tornadoes, and droughts, as well as sinking land and water scarcity in some areas. To address these issues, this paper proposes a rainwater harvesting system integrated with a triboelectric generator for electricity and drinking water purposes. Experimental results show that the triboelectricity generated from rainwater depends on the rate of falling droplets, the height from which they fall, and the coverage area of hydrophobic material. The electricity generated by the nano-hydro generator is proportional to the flow rate of water, with an observed voltage of 71.8 mV at an average flow rate of 49.05 ml/s.
