The Aeolipile
Hero, an Egyptian scientist from Alexandria, developed the first "jet engine" about the year 100 BC. Known as the "aeolipile" (Figure 1), it consisted of a boiler, two hollow bent tubes mounted to a sphere, and the sphere. Steam coming from the boiler entered through the two hollow tubes supporting the sphere. The steam then exited through the bent tubes on the sphere, causing it to spin. Hero is said to have used this invention to pull-open temple doors.
