In a world where 25 men scrounged a living with their muscles for every one who made a living any other way, Nikola, before he was five, played with another source of power. The use of wheels to harness water power was as old as history. From the disk of a tree trunk he made one, set it up as shown, and watched as the current’s force turned it. #nikolatesla #teslacoil #tesla #electricalengineering #electricity #electricalengineers #electricalengineer
