By imposing nematic anchoring at the substrate while active flows induce a preferred alignment at the interface (\"active anchoring\"), we demonstrate that directed fluid flow spontaneously emerges in cases where the two anchoring types are opposing. In one dimension, our model reduces to an analogue of a loaded elastic column.
