Alternating current (AC) induction motor: Tesla is credited with the invention of the modern alternating current (AC) induction motor, which revolutionized the field of electrical engineering. It allowed for the efficient transmission of electrical power over long distances and became the foundation of the modern electrical power grid.

Tesla coil: Tesla developed the Tesla coil, a resonant transformer circuit widely used today in wireless power transmission, radio communication, and medical imaging. The coil generates high-voltage, high-frequency currents, producing impressive electrical discharges and lighting effects.

Wardenclyffe Tower: Tesla began construction of the Wardenclyffe Tower, also known as the Tesla Tower, with the ambition of developing a transatlantic wireless power transmission system. His groundbreaking vision, though ahead of its time, went unrealized due to financial setbacks.

Fluorescent lighting: Tesla conducted pioneering work on fluorescent lighting, experimenting with gas discharge tubes. His insights contributed to the later development of efficient fluorescent lamps.

Radio communication: Tesla played a vital role in the development of radio communication technology. He invented and demonstrated early prototypes of radio broadcasting devices, contributing to the advancement of wireless communication systems.

Remote control: Tesla made noteworthy progress in the field of remote control technology, successfully piloting an early radio-controlled boat during a public demonstration.
