The way too long film gets down to this. Fusion power output is not the same as net power. When considering the energy needed to run it, the ITER fusion reactor produces zero net power. In fusion research, this is considered an achievement because previous designs had negative net outputs. The author's objection, and rightly so, is that the total output is being sold as the net or useful output in order to get continued funding, while the actual project produces no usable power above what it consumes.
