In 1650, Otto von Guericke invented the air pump, used to create a partial vacuum. Using hollow copper spheres and an air pump of his own construction, Guericke demonstrated that a partial vacuum could be created by pumping the air out of the sphere.
Archimedes also invented the spiral pump (still widely used for irrigation in many countries) as well as war machines such as improved catapults, ray cannons based on focused sun beams, land-based cranes to lift and sink attacking ships, etc.
