Bioelectrochemical propulsion.
A carbon fiber having a terminal glucose oxidizing microanode and an O2 reducing microcathode is propelled at the water-O2 interface. The electron current in the fiber is accompanied by a flux of hydrated protons that is so fast at the solution-air interface, where the viscous drag is small, that the fiber's velocity is 1 cm s-1.
