A voltage difference is detected in the “generator” part of individual water-filled SWNTs when a current is applied on their “motor” part. It is suggested that the measured voltage difference reveals a newly induced electromotive force, which is generated by a water flow inside the SWNT. The water molecules in the nanotube channel are in turn dragged to flow by the current applied on the “motor” part.
