Watch this 90-minute documentary about the story of Nikola Tesla and his achievements from the early 1900s. He was overshadowed by many famous inventors in his day and was never given the recognition he deserved—to this day. He was considered the inventor that kick started the Industrial Revolution.
In Teslafy Me (2019), I learned his patents and ideas are still being used today and remain unchanged. He believed in renewable energy and that energy should be provided to the world for free. His technologies were ahead of their time. He believed in free wireless power transmission and had ideas for cell phones and internet. He was definitely a genius and we are only finding out about him today.
