Tesla had a lot of ideas, but unfortunately he did not have the money to realize it, only a few and by lending money. Such a shame, since he was a real inventor. I am not sure if Tesla's idea of a spacecraft was possible, but maybe his idea was not that strange. Lately we are hearing a lot of strange phenomena in this area. Who knows?
A NASA hacker revealed about a year ago that they have spaceships, maybe they used Tesla's idea?
