I remember when I was a student and we visited a nuclear plant. At the time we were told that we were probably 20 years away from commercial fusion reactors. That was in 1990. Any sign of fusion nuclear plant? 😉
There is a big difference between teletransporting a photon, an elementary particle, and a human being!

Even if this was possible, is creating an entire copy of a human being somewhere else truly teletransportation? Is the clone the same person? What if the original is not destroyed? 😁
See The Illusionist movie for an entertaining idea!
