Nikola Tesla was a visionary inventor who devoted his life to making an abundant, clean energy supply for humanity. Among his inventions toward that end were alternating current (AC) power transmission, the AC motor, and the bladeless turbine. He also invented radio, neon & fluorescent lighting, x-ray imaging, robotics, wireless remote control, wireless energy transmission and more. And in 1900, he described his World-System of wireless communications, which has a notable likeness to the Internet.
