Liquids are usually described within classical physics, whereas solids require the tools of quantum mechanics. I will explain how in nanoscale channels, this distinction no longer holds [1]. At these scales, the liquid flows become intertwined with electron dynamics in the channel walls, resulting in a wealth of phenomena beyond the reach of classical fluid mechanics. I will discuss the fluctuation-induced quantum friction effect, and, after a detour through quantum spin glasses [2], highlight its implications for hydroelectric energy conversion at the nanoscale [3].
