Where are you getting this impression? Her video pretty clearly focuses on the confusion between the Qs. Where does she get the napkin math wrong? She uses a published figure for total energy required during the operation of ITER when it’s up and running not a one time startup cost figure. Id she misrepresented that number, what would be a more honest total power consumption figure? As far as construing the output, she uses existing loss ratio for heat to electrical energy conversion which really does not seem to work to construe the problem as “especially difficult”, it’s “normally difficult” is how I interpreted. Are there impending advancements in energy conversion that makes 50% too liberal?
