Remember learning about osmosis in middle school or high school? In case you don’t- it’s the transfer of salts from water with a high concentration across a membrane into water with less salts? Energy can actually be released from this process (osmotic power), but most techniques that have been studies haven’t produced a reasonable amount of power using osmotic energy. A new study uses boron nitride nanotubes to attract cations (salts with a positive charge) and enhance the movement of the salts so that the intensity of the current from osmosis is more than 1000 times higher than in other research!
