Electric Motor
Tesla’s invention of the electric motor has finally been popularized by a car brandishing his name. While the technical specifications are beyond the scope of this summary, suffice to say that Tesla’s invention of a motor with rotating magnetic fields could have freed mankind much sooner from the stranglehold of Big Oil. However, his invention in 1930 succumbed to the economic crisis and the world war that followed. Nevertheless, this invention has fundamentally changed the landscape of what we now take for granted.
