Cellular processes involve the movement of many forms of materials involving both active and passive processes. Described here is the phenomenon by which micrometer sized oil droplets, created with a nonionic surfactant, move spontaneously through solution being propelled by the large scale movement of ions, with hydrogen ions being able to move oil droplets across a smaller gradient. This has implications for both artificial life development as well as questions concerning the mechanisms regarding the emergence of life.
