Single‐pore osmotic power generators show ultrahigh power density. But, when scaling up to real porous materials, their performance drops by orders of magnitude. In article number 1804279 , Wei Guo and co‐workers unveil the origin of this giant gap, and point out how to equally achieve kW to MW m −2 power density in membrane‐scale applications.
