"Many large cities around the world experience frequent power outages and yet have an abundance of tall buildings and experience rainfall. This represents a unique and scalable opportunity for cities to capture the intermittent rainwater at high elevation and convert the potential energy into electricity for rechargeable batteries at street level when solar panels are unproductive. Through a global data analysis, we demonstrate there are indeed numerous large cities with a non-negligible potential for harvestable hydropower using an easy-to-implement concept called Self-sufficient Harvester of Electricity-Water. In an effort to aspire toward a more sustainable way of urban living, we now urge the scientific community to reimagine large cities with tall buildings as untapped sources of hydropower whose intermittent nature could be stored in rechargeable batteries to provide a more stable backup for low-power but essential services during outages."
