The energy needed to teleport someone makes it IMPRACTICAL, but even if you could beam-up, would you want to?

Possible To Teleport A Human?

As air travel gets more tedious, the idea of simply popping into a booth on one side of the world and reappearing on the other gets even more appealing. Standing in the way of this, however, are a tremendous number of technical issues. It may be possible to teleport a very small item, such as a virus, but for anything larger there are physical limits that mean it would be necessary to do the transfer particle by particle.

Even leaving aside our inability to manipulate matter accurately at that level, the sheer size of the problem is phenomenal. A human body contains around 7×10^27 atoms ( where 10^27 is 1 with 27 zeros following it). Imagine you could process a trillion atoms a second. It would still 7×10^15 to scan a whole person. That’s 200 million years! There’s also a huge amount of data to be transmitted with an associated energy cost. A conservative estimate estimate puts this around 10^12 gigawatt hours. The UK’s power station capacity last year was 83 gigawatts. So teleporting one human would tie up the UK power supply for more than a million years.

Even if it were feasible, sensible travelers would hesitate to make use of a teleportation device. Bear in mind that it would not move you from A to B. Instead it would strip you down, atom by atom, disintegrating your body, and building an identical copy. Yes, the teleported ‘you’ would seem the same to everyone else – with the same thoughts and memories. But it would be a copy and you would be destroyed. Even airport security isn’t that bad. 😉
