Does this mean that if a reactor/engine system had an efficiency higher than ~6% a Focus-Fusion-powered 747 could fly? If not, why not?
Oh that’s easy. Just use the electricity to run high voltage/high temperature electrolysis of a saline solution at or close to the point near the jet engines that are going to burn the Hydrogen/Oxygen mix. About the same overall weight, a little more thrust and the fuel isn’t explosive outside the engines.
