Unless you have a energy source that weighs next to nothing, or you somehow can decrease your mass down to next to nothing you will never go as fast or faster than light. (E=m*c² and all that jazz)

Wouldn't you technically need an energy source that wouldn't increase in mass if you require more energy? The weight of the initial energy source doesn't matter, it just needs its weight to stay constant as it's energy output scales up infinitely.

Which, y'know, goes against the laws of thermodynamics.
