Nanochannels for power generation: The confinement of fluid motion in a single boron nitride nanotube can provide an efficient means of power harvesting owing to the osmotically driven streaming current under a salt concentration difference (see picture). Devices based on this principle may open a new avenue in the exploration for new sources of renewable energy.
