The AC-based power system is the foundation of modern power generation. Contemporary ways in which we get electricity in our homes, schools, and offices were built on advances that came from Tesla’s invention. The 60-day cycle in which the power frequency changes direction was originated by Tesla's polyphase AC motor and is still being used by power plants today.

Even though direct current lost the War, it still generated other significant advancements in electric distribution; some are still being used today:
Tesla's whole life seems unreal, as if he were a fabled create of some Olympian world. A reporter, after writing a story of his discoveries and inventions, concluded, "His accomplishments seems like the dream of an intoxicated god." It was Tesla's invention of the polyphase alternating-current system that was directly responsible for harnessing Niagara Falls and opened the modern electrical superpower era in which electricity is transported for hundred of miles, to operate the tens of thousands of mass-production factories of industrial systems. Every one of the tall Martian-like towers of the eletrical transmission lines that stalk across the earth, and whose wires carry electricity to distant cities, is a monument to Tesla; every powerhouse, every dynamo and every motor that drives every machine in the country is a monument to him.

Tesla’s success led to increased funding for his company. This is where he developed key technologies that not only broke barriers but would also change the world.
