The question is, who will be the pioneer, so to speak? Who will undertake and lead this project?
how "they" keep all technologies in secret is not clear. At my friends dads engine, the engine was running on gasoline diluted with water. He himself modified the engine. Dad from the district center, an ordinary engineer, tried to put his invention to the benefit of people and nothing came of it. It will be difficult to go against the system in any case.
