Scientists Create World's Smallest Steam Engine
First time accepted submitter Virtucon writes "German physicists say they've built a heat engine measuring only a few micrometers across which works as well as a normal-sized version — although it sputters, they admit. Researchers at the University of Stuttgart and the Max Planck Institute for Intelligent Systems say that the engine does basically work, meaning there's nothing, in principle, to prevent the construction of highly efficient, small heat engines."
What was it Sheldon said on big bang theory, half the size, twice the fun.
The mexican cartels gotta innovate. Thousands of micro trains hauling micrograms of coke across the border in microtunnels!
you can't stop what people want.
