I would probably travel back to the 1920s and make sure that Tesla's inventions came to fruition rather than being seized by the FBI upon his death never to be seen again. I truly believe his inventions would have changed the world as we know it.
Tesla was a gift to humanity... Our rulers will destroy anyone like him nowadays usually with regulation to make the merica a "safer" place.
I am with this idea however I cannot see how you would pull it off
