What I am not understanding is how this has been kept a secret? Am I to expect now the men in black to turn up and shoot me with their heart attack gun?
The best about this (on the technical level) is that they cannot delete the published information. No one can. Because it is published and stored on a blockchain. The information will be available on it as long as the blockchain works. And the blockchain is storing every edit, so it is not possible to censor the content. They would have to shut down the whole blockchain to "hide" any published thing on it.
Probably Tesla and other scientists knew much more about the free energy, but the "man in black" destroyed (or simply hide) many related things. I heard about a water powered car too, and I also heard that its creator misteriously dissapeared with the car. So the authorities can put people away, if they know "too much".
Like I said in my post, I don't think what I am doing here is anything new or amazing. It's actually just old info, still taught at school in some places, but people seem content these days to know the information without ever taking action to see what else they can learn from it. It feels to me like people believe all the great things have been discovered already. And while this may be true that is not to say that they cannot be re-investigated. Sometimes the most amazing things have been left hiding in plain sight.
I also heard about the water powered car. That, it would seem, was too much for the establishment to take. Earth batteries on the other hand they seem okay with us having. Which is great news!
