The Mechanics of Atmospheric Engines: Power from the Air
Unlike internal combustion engines that rely on the rapid burning of fuel, atmospheric engines operate using the pressure difference between a vacuum and the surrounding atmosphere. Typically, a piston is raised within a cylinder, creating a vacuum beneath it. Atmospheric pressure then pushes the piston down, generating power. This downward motion is then converted into rotational force to drive the wheels. While conceptually simple, the practical implementation presented significant engineering hurdles.
The earliest examples, like the Newcomen engine, were primarily used for pumping water, but inventors soon sought to adapt this technology for transportation.
