A novel floating droplet electricity generator (W-DEG) uses natural water as both electrode and substrate, achieving high outputs comparable to metal-based devices but with 87% less material weight and 50% cost savings. Water’s high surface tension and conductivity enable efficient energy harvesting and unidirectional drainage. Scalable to sub-m² devices, W-DEG offers a sustainable, land-free path for hydrovoltaic power in diverse environments.
