Tesla's most important invention is widely considered to be the alternating current (AC) system, which revolutionized the way electricity is transmitted and distributed.
Tesla’s early experiments with wireless energy transmission laid the groundwork for modern technologies like radio, Wi-Fi, and Bluetooth. His vision of a wirelessly connected world became the foundation for global communication systems.
Today, Tesla coils are mainly used for educational demonstrations and entertainment. However, the principles behind them still influence technologies in radio transmission and electromagnetic research.
Organizations like InventHelp assist inventors by providing guidance, resources, and support throughout the entire invention process—from idea evaluation to prototyping and marketing.
Tesla is considered a visionary because he imagined and attempted to create technologies far ahead of his time. Many of his ideas, including wireless communication and sustainable energy, have only recently been realized, highlighting his extraordinary foresight.
