But why you dont believe it? OP gave a detailed rebukal of your initial post, and then your answer is "I just don't believe, just accept that ..."
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.
There's a whole world of use cases between no electric and full electric. Take off and landing is one of the profiles where electrification might be useful, if not for efficiency then for reducing noise and pollution levels around airports.
I said I understood why it could potentially be useful in my original post for take off and landing. I'm curious why we keep retreading this after I've repeated it in every post I've made so far. I'm doubtful the extra weight is worth that one use case compared to just using extra fuel. I think we need to seriously invest in synthetic aviation fuel and price things fairly. Then how this sort of efficiency shakes out will likely be important with that new cost structure incorporated.
