Why would teleportation generate waste heat? It's not super-speed, you aren't actually accelerating or decelerating, or passing through anything between points A and B. That's kind of how teleportation in literally all fiction works. Space-Folding.<br><br>Not sure why he thinks Teleportation would let you push an asteroid either. Flight (like superman's) is control over momentum. The ability to move in any direction and accelerate without anything to push off. Teleportation by definition has no momentum, because you aren't moving.,(reply>), Because by teleporting you are gaining or losing potential energy. <br>Also, he didn't say anything about pushing asteroids. He just said that you can let them go in the air and let them fall.
