The study of sap transport in trees finds its origin in the late 19th century. Trees are designed in a way that allows them to passively transport fluids against relatively high amounts of pressure. In the beginning of the 20th century, Edward W. Washburn wrote an equation that described the propagation of fluid through a channel by means of capillary forces and viscous effects. Nowadays, through aid of micro- and nanomachining, researchers are able to test Washburns equations in ever smaller fluidic channels.

This presentation will show a new way of combining active condensation on a nanostructured surface that allows passive transportation against high amounts of pressure. Fluid is transported from the roots of the chip to the leaves of the chip where in a later stage evaporation and/or electrolysis might be performed to allow a constant mass transportation.
