Brainlet cross-boarder here, explain this to me in workin' mans words.

Wouldn't efficient teleportation violate the first law of thermodynamics because of potential energy? If gravitational potential energy is mgh then to not violate this law the teleportation process would have to, er, expend equal to or greater than the gain in potential energy if teleporting it upwards? Else if the energy used in teleporting is less than the gain you've created energy?
