Discoveries that changed the world | Windmills

Arab Weather - Humans need a source of energy for work and production, and before the invention of oil-powered machines, sustainable energy sources such as water and wind were used, and because of Muslims' creativity in inventing mechanical machines, they invented machines that depend on the crankshaft system to lift water and operate Wheat mills, but due to the lack of sufficient water in Islamic countries permanently, Muslim scholars sought to exploit the winds, especially the desert winds that blow regularly, and the windmill appeared.

In the year 634 AD, a Persian man came to the Caliph Umar ibn Al-Khattab and offered him a new invention to build a windmill, then the idea of a windmill spread to be used in operating the millstones of mills to grind grain, raise water and water the earth. The invention of the windmill and water mill contributed to the flourishing of mechanical engineering, and created opportunities for new professions from building mills to their maintenance.
