Por supuesto que ese principio es rigurosamente cierto, pero la dura realidad que llamamos Entropía impone que esa transformación desemboque en una energía degradada, no recuperable (o muy difícilmente) para cosas prácticas. ¿Cómo recuperar por ejemplo la energía empleada en producir una tonelada de aluminio? ¿O la energía del combustible gastado por un avión en un trayecto de 5.000 km?
