That's just not true, and skirts the line of the being a deliberate lie. Fusion has occured in tokamaks, at an efficiency of 65%. ITER, as currently designed and being built, is expected to make a 10-fold return on energy input. We are precisely at the position of "the math is all there" with regard to magnetic confinement. And so is the engineering and the funding (barely). It's going to happen, hopefully not before…
I should mention that in the past, I worked on the software backing research tokamaks. ITER is a research project. It is not designed to produce electricity. It was originally projected to cost over 5 billion pounds to build and has now tripled, but is years from completion. Even if it was successful beyond its wildest dreams, the best result would be that we'd have to spend another $50B to build a plant, and since t…
