Countries (corporations, like The United States of America) do not want free energy. The people of these nations want such. But, T.P.T.shouldn'tB. do not want it ever.
Did you know that Kalifornia tore down one of the early solar power plants. Solar Two is now gone. :~(
There was an initiative to develop fusion energy. And just about the time they were starting to get to unity, The US pulled out its funding of the project.
Also, all inventions of note were invented in a garage.
Nothing important has ever been developed by big business.
These big businesses are looking at if we make or create this we won't have anymore income or control, so they really want people to live under their thumb. I think if we want true freedom we need to get that old way of thinking out. but for governments and business that probably a hell no. we might have to get a very wealthy person to do it just to lead the change and do it solo, so no country or government would stop him or her doing git.
