    "abstract": "We develop and analyze a model for ratchet-driven macroscopic transport of a\ncontinuous phase. The transport relies on a field-induced dewetting-spreading\ncycle of a liquid film with a free surface based on a switchable, spatially\nasymmetric, periodic interaction of the liquid-gas interface and the substrate.\nThe concept is exemplified using an evolution equation for a dielectric liquid\nfilm under an inhomogeneous voltage. We analyse the influence of the various\nphases of the ratchet cycle on the transport properties. Conditions for maximal\ntransport and the efficiency of transport under load are discussed.",
