ArchaeoDesigns's video: Ancient Greek Automobile Reconstructed: Heron s Aeolipile

Original archaeological reconstruction for what could have been the world's first automobile, utilising the known technology of Hellenistic age Greek polymath Heron and his famous Aeolipile (circa 10ad-70ad). Effectively the predecessor of the industrial age's steam engine. The aeolipile consists of a vessel, usually a "simple" solid of revolution, such as a sphere or a cylinder, arranged to rotate on its axis, having oppositely bent or curved nozzles projecting from it (tipjets). When the vessel is pressurised with steam, steam is expelled through the nozzles, which generates thrust due to the rocket principle as a consequence of the 2nd and 3rd of Newton's laws of motion. When the nozzles, pointing in different directions, produce forces along different lines of action perpendicular to the axis of the bearings, the thrusts combine to result in a rotational moment (mechanical couple), or torque, causing the vessel to spin about its axis. Aerodynamic drag and frictional forces in the bearings build up quickly with increasing rotational speed (rpm) and consume the accelerating torque, eventually cancelling it and achieving a steady state speed. Typically, and as Hero described the device, the water is heated in a simple boiler which forms part of a stand for the rotating vessel. There has been much debate as to whether Heron's invention could have spurred the first automobile of the Greek World, however no evidence suggests he or his successors used the technology for this purpose. I designed this conjectural piece to portray what could have been 2000 ago with all the able technology at their disposal (also imagine the technological advancement today should all the stages of the industrial revolution have happened in the distant past rather than a century ago). Two sculptures of wild boar are moulded into the carriage to show even if engineering capability allowed for automatic power, the social climate of the Greeks may have still fancied the prestige and symbolism of an animal drawn carriage, an interesting clash of cultures. The boiler in my case is attached to the main cog, and when a lever closes the sphere, air expels through two holes forcing the cog to rotate, in turn rotating a lineal cog twice the size and amount of keys (spinning exactly half as fast as the main cog) joined to the back wheels.
