Let’s say that, through whatever improbable means you wish to postulate, you came into possession of technology allowing teleportion. For the sake of this discussion, assume it’s space-warp type technology requiring both transmitter and receiver: i.e., no bodily duplication or destruction is involved, and the teleportee remains conscious & aware during the entire transport. In other words, you walk into the teleport booth in New York, say; the door closes behind you, and the floor rotates so that you are moved 180 degrees from your starting position; and then the door opens in front of you, and you find yourself in London. The theory underlying the teleportation process is such that the it is inconceivable that it could be accomplished without a booth at both ends. The teleporter’s distance is limited to terrestrial distances; even if we went back to the moon, you could never 'port directly there. However, it makes no significant difference to the energy or material costs whether you’re teleporting one mile or ten thousand; the mass of the teleported object or person doesn’t matter either, only the volume and shape (in that the object has to be small enough to fit through the doors of the booths.) At the largest possible size, the booths can be made with so that the doors are twenty feet high by twenty feet wide. Lastly, operational costs are such that transporting a an object the volume of an average human costs about ten times as much as a first class airplane ticket from New York to Tokyo.
What effect would such a device have on the world? How would you market it?
