I love Tesla!
He was able to send electric current wirelessly to light bulbs on a ship far from land and proposed using the earth's magnetic field to power industrialization.
To me, the most fascinating aspect about him was his mind. It is believed he was able to build his inventions, break them down, fix them, a few iterations all in his head before he ever built them!
Great post!
Thank you, indeed, and he could visualize them in front of him. Nikola Tesla needed no model to test his inventions; they appeared before his eyes as functioning realities that he could stop and start as though they were really there. https://teslauniverse.com/nikola-tesla/articles/miracle-mind-nikola-tesla
