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.

To swing a playground swing, push it in rhythm. That's how you use resonance — amplifying oscillations when the beat matches. A similar mechanism twists hydroturbine shafts when they receive electrical jolts from AI data centers. Modern AI servers consume energy unevenly: millions of processors suddenly kick into action, then go quiet.
