“free energy”, better described as zero-point energy
There are other potential sources of free or very low cost energy, zero-point energy is just one of the better known. Same problem when you talk about electro-gravitics, there are potentially a lot of ways of manipulating gravity.
There are numerous ways of maintaining secrecy and suppression that we will also cover in future articles.
The internet renders them all obsolete. If you actually discover a source of energy or gravity manipulation publish to a bunch of news sites and other widely used sites of any type and there would be no way to cover it up neatly.
If only the Rothschild bloodline was replaced by Nikola Tesla’s.
And there it is, dropping into outright conspiracy theory nuttery.
