Yep, I’m still waiting for the unmetered electricity that I was promised 60 years ago when I was a kid visiting fission pilot plants.
The US and UK were particularly adverse to nuclear energy, since they wanted to keep a monopoly on atomic weapons and maintain their grip on energy through the Anglo American oil companies.
The latter are no longer a factor, and other countries are now ready and able to advance the field. France, Russia, and China lead in fission reactors. France, China, and Japan lead in fusion.
