Driven by natural or artificial sunlight, a novel 'microtube pump' transports water droplets over long distances. The pump consists of a tube whose properties can be changed asymmetrically through irradiation. This results in capillary forces and a wettability gradient in the inner wall which work together to accelerate the water droplets to exceptional high speeds.
