I have seen a few posts concerning the teleportation of materials, vehicles and the player(s) but noted some pretty good comments with regards to making vehicles and other modes of material transportation obsolete.
My suggestion is to eventually have a personal teleportation station added to the game that only allows players (and their personal inventory) to pass through. It would be less about procuring an easier means of transporting materials and more about reducing unnecessary time spent traveling between bases (particularly in the late-game). This would allow players to enjoy more time building and expanding their factories far from their main base of operation rather than spending a decent chunk of the time running or driving to specific locations.
I am sure a teleporter would likely call for a good bit of energy to operate, however, I won't claim to know a good value for the MW usage. With regards to actual use, a player would simply construct the teleporter (after unlocking it), connect it to power, and then link it to other teleporters that have already been constructed via UI. Although it may be apparent, a single teleporter will not function on its own since it does not have an alternative point to teleport to (unless the main HUB counted as a location to teleport back to).
