The boat was not Tesla's first attempt at radio transmission and reception. How long had that boat been in planning and testing stages BEFORE it was put on display? Many people know things that can work but have not tested them so they remain ideas. Jules Verne had ideas that were not tested and found part of reality for many years. And da Vinci had similar ideas. And what about the man who said that the earth revolved around the sun? He was jailed because he did not toe the line with all those others who had a differing theory. There are some things that mathematical and aeronautical experts said could not work but prototypes were made and they were found to be workable. Others, like Velikovsky, were feared because they upset standing theories. In retrospect, they are found to have correct views and theories. The idea that the old masters have to be dead for 50 years before a new theory is contemplated is not always true because there are still some who say Velikovsky was a fool. However, he is now being seen as someone with good theories, much better theories than those of the people who were against him. Same as Tesla. Marconi had his opportunities and he took them and succeeded by them. Tesla is seen by those same people as unrelated to radio while the elements and functions of much of what Tesla did were used by others in their experiments. What Tesla did is still inspirational to those who lack imagination. Closed minds deny this, however.
