Nikola Tesla imagined a world where energy would be clean, free, and drawn directly from nature’s forces. Throughout his life, he developed concepts for harnessing the sun, wind, and the very ground beneath our feet, seeking to replace finite fuel with sustainable sources. Tesla believed that understanding Earth’s energies was essential to humanity’s future. His ideas underscore the importance of stewardship and respect for the planet we inhabit, urging us to innovate responsibly and rethink our relationship with nature.
