ENGINES

[2 Chronicles 26:15]

And he made in Jerusalem engines, invented by cunning men, to be on the towers and upon the bulwarks, to shoot arrows and great stones withal. And his name spread far abroad; for he was marvellously helped, till he was strong.

The People of God is the First inventors of ENGINES

An engine or motor is a machine designed to convert energy into useful mechanical motion.Heat engines, including internal combustion enginesand external combustion engines (such as steam engines) burn a fuel to create heat which is then used to create motion. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others, such as wind-up toys use elastic energy. In biological systems, molecular motors like myosins in muscles use chemical energy to create motion.
