These huge machines wander through space, searching for scrap metal from which they extract useful parts and use them to upgrade themselves. That could be seen as if they’re feeding on space junk, although they source the heat energy from stars and once they collect enough to be able to transform it into operation-sustaining electricity or the tachyon-based warp propulsion.
