Thank you so much for this amazing and interesting article, Silek!
It's fascinating to read about all the theories, researches and tests that are going on. In my opinion mankind will be able to use this technology some day. Don't ask me when, but it will be possible, although -as Silek mentioned it correctly- this will require LOTS of energy, time and resources. But isn't it amazing to see that many, many things for example Captain Kirk, Mr Spock or Bones used as "science fiction gimmicks" in TOS back in the sixties have become part of our daily life today? Smartphones, tablets - Silek has mentioned these things too.
Even the Ancient Romans knew:
"Scientia potentia est" - this makes me confident when looking into the future.
