Please excuse my lack of knowledge/understanding.
Question: Why Nikola Tesla's Free Energy concept was never worked upon? Even today.
Context: Now that we know Nikola Tesla was a genius and did exceptionally well with his works and the Free Energy concept. Why his idea was never adopted or was worked upon, even now? I know, back then, Edison didn't let him do much. But now, in our times, why GE or any other company or well the physics
PhDs aren't following up? Why CERN is not working over it?
By the articles that I have read over the internet I am under an impression that everyone (now) feel that we have "missed" the free-energy chance that we had as a planet, that Nikola Tesla was trying to bring in. I see a lot of brag (to an extent, as well) which leaves no doubt that his Free-Energy concept would have been must-have.
But if I look at the actual followups, no one it seems got actually interested to pursue his theories; or is it that no one is capable enough to do it? Which would be strange, given that we are at the peaks of technological advancements. How hard is it to build a prototype? Really?
Or people might have worked over it, but Tesla's blue-prints were not correct, and that is why no one came up with the actual implementation of it? Or is it that he was really a crackpot as politically-publicized by Edison?
I would really appreciate an answer, because this is beyond me, to understand why no one followed up on this concept?
Thank you, in advance.
