You could put a portal on the bottom of a lake, on a chamber with a valve on top, with water draining throught it, and the other portal feeding a hidropower turbine on top of the same lake in a concrete surface, and let it fall a good height before reaching the turbine with extra energy. The forever stream of water falling through the portals back to the top and generating energy on the turbine suggests that either a teleportation portal like the one in the game is impossible, or it should spend an equal amount of energy to move anything up through it as the net gravitational \"height\" field between the portals, thus negating the net positive energy, or you\'d get a PerpetualMotionMachine from the start.

Another evidence of the game portals being impossible is that you can speed up indefinitely with 2 aligned portals.

Since the game allows opening a portal on the moon without extra energy, this thought experiment proves the game version of teleporting with portals would be impossible in real life.

Admittedly, a version that spends a lot of energy to move stuff \\\"up\\\" on the gravity field would still be awesome and hella useful.

Another evidence of that is that you can speed up to the freefall speed limit with 2 aligned portals.
