Scientists create "the world's smallest steam engine"

Scientists create "the world's smallest steam engine": "It sounds implausible, yet scientists have managed to create a functioning engine, analogous to a Stirling engine, just three micrometers wide and made of a single particle. The minuscule engine was created by Clemens Bechinger and Valentin Blickle at the University of Stuttgart, and though it has its quirks, the pair have apparently demonstrated the engine's ability to do work."
