You want to know why I don’t believe we’ll get batteries with enough energy density for sustained long haul flight? I was responding to their last sentence. Ya know, acknowledging that batteries more dense than hydrocarbons isn’t really on the radar so for that aspect of things synthetic aviation fuel is pretty much what you gotta accept to go for zero carbon. I had already agreed with them that it’s potentially more efficient in takeoff in my initial post. They just expanded on why. I frankly am perplexed at what you think I’m dismissing since we largely agree.
