What you've described (badly) is simple Newtonian acceleration and has nothing to do with relativity. And yet you've got a simply accelerated object with more energy that what it started with, in apparent violation of conservation of energy. Hmmmm... Got any idea how this is really supposed to work, NoEinstein? Feeling foolish today?
