Persian philosophers and inventors may have created the first batteries (sometimes known as the Baghdad Battery) in the Parthian or Sassanid eras. Some have suggested that the batteries may have been used medicinally. Other scientists believe the batteries were used for electroplating – transferring a thin layer of metal on to another metal surface — a technique still used today and a common classroom experiment

Ca. 1700 BC, windmills were developed by the Babylonians. They were used to pump water for irrigation. In later times, Persian inventors developed a more advanced wind-power machine, building upon the more basic model that was developed by the Babylonians

I think Persian engineers are also credited with the invention of the dome…although that may have been the Romans.

Hope help good luck. good old days!!
