Eldorado Posted August 22, 2019 #1 Share Posted August 22, 2019 "The engine itself—a single calcium ion—is electrically charged, which makes it easy to trap using electric fields. "The working substance of the engine is the ion's "intrinsic spin" (its angular momentum). "This spin is used to convert heat absorbed from laser beams into oscillations, or vibrations, of the trapped ion. "These vibrations act like a "flywheel", which captures the useful energy generated by the engine. "This energy is stored in discrete units called "quanta", as predicted by quantum mechanics."
