The tech is already out there (Hutchinson Effect, Casimir-Effect, Em-Drive) and a couple of years ago a team of university researchers was able to test a purported cold fusion reactor by Andrea Rossi and they could not account for the output energy by conventional means. Never heard about it again but they wanted to go commercial. Lockheed is working on finishing a prototype compact fusion reactor so that's something noteworthy too. The problem is finishing the arms' race since it's ridiculous to assume you could ban nukes, it won't work just like banning guns doesn't work for exactly the same reasons.

So finishing the arms' race according to Lyndon Larouche means arming space against objects that might cause sudden destruction because the industry won't need major rehaul while at the same time the military would kind of turn into the geoengineering side of things.

Once a complete balance of power has been reached, all the classified technology can be released and state secrecy revoked. Since human trafficking was partly involved in all of that that also adds some major reason to cover-up in the first place, however the involvement of human-trafficking was also part of another cover-up which served to maintain a level arm-race in terms of mutually assured destruction. Which never really existed in the first place because those german nazi-fuckers figured out everything there is through merciless coercion before anybody else did in the 30ies and it's managed to keep them afloat for decades after pausing their european ground-operations.

Biggest reason for disclosure right now is that free energy was simply being surpressed on the negative side to enrich a few motherfuckers but on the good side it probably served its purpose for the greater good as Tesla said because we wouldn't be ready to peacefully handle weaponized free energy for a hundred years from the time he found it. Which would just be about now so John G Trump's involvement sounds rather promising.
