anachronism.
That is an interesting username, and seems very appropriate for describing Nikola Tesla and his type of thinking.
"The most common type of anachronism is an object misplaced in time, but it may be a verbal expression, a technology, a philosophical idea, a musical style, a material/textile, a plant or animal, a custom or anything else associated with a particular period in time so that it is incorrect to place it outside its proper temporal domain."
