Have you ever wondered how that steaming hot cup of coffee gives you that boost of power that you need? This is how it works.
A cup of coffee is pretty much a steam engine, no? Well, in any case, this is technically a feasible model steam engine. Starting at the top left, the gas heats up the water in the broiler and the steam passes through the coffee cup handle into the lubricator and into the cylinder, which moves the piston and any other kinetics like the gears and flywheel. The two spinning balls at the top regulate the amount of steam in the cylinder by opening a value. From the cylinder, the steam passes through the compressor which releases exhaust and back into the broiler. Or at least pretty much.
