a wheel that hoards spin like a dragon hoards gold, releasing it on demand
means A heavy rotating wheel that stores rotational energy and smooths out fluctuations in a machine's speed, releasing momentum to keep things turning steadily between power strokes.
from A plain English compound of "fly" and "wheel," dating to the 18th century in the language of early machinery. Here "fly" carries an old mechanical sense — a part that moves or swings freely, as in the regulating "fly" of a clock — so a flywheel is literally a wheel that flies on under its own momentum. The term hardened into engineering vocabulary during the steam age, when massive iron flywheels kept engines from stalling between pistons' pushes.
