A heat engine is like a sailboat: to move forward, it needs a difference. Usually that means a temperature difference between hot and cold reservoirs. But what if the reservoir itself starts moving? The wind that fills the sails is created not only by a pressure difference but also by the motion of air masses.

Picture a chef flicking water onto a sizzling skillet. The droplets instantly hiss and evaporate, giving immediate feedback on the temperature — far quicker than any thermometer. This intuitive idea underpins a new approach in quantum thermometry.
