Let's go back to the difference between accelerations and uniform (relative) motions, in relativity. I stated that it doesn't matter what you set your speed to, relative something else, earth, asteroids, your shoe or the rabbits, whatever. There is no measurable change in your rest mass, that light bulb won't glow any stronger just because you're in a new, faster, relative motion. But heat up a piece of iron and its weight will change.
