      Electric airplanes are highly inefficient and not really good enough for commercial use.

          That’s unlikely to change for long distance flights.

          For short flights small electric planes are becoming viable already, and they will continue towards medium flights over time.

          But theres no serious concepts for a battery that could compete for long flights.

          That’s not to say that planes are doomed to be fossil dependent forever. But the likely solution will be a renewable high density fuel, possibly hydrogen or something easier to carry.

          It’ll be less efficient than batteries on a energy in to work out basis, but once the cost of carrying the weight is considered, that will always swing way in the favour of high density fuels regardless of battery efficiency (for long distance).

      Almost every movie or show I’ve watched since I was a kid featured a cool shoot from the hip maverick that didn’t have time to do that nerd shit like making ethical safe choices or pondering over the legitimacy of some grand conspiracy. They never needed too. They all live in a world where grand conspiracy’s existed.

      30 years later my generation grew up and have a lot of media stored right next to actual memories. So egg heads are evil spineless nerds that work for evil faceless organization. The real hero’s are the guys that shoot first ask questions later.

      It’s so much easier to sound completely sure of yourself and like you’re obviously right when you don’t know all the details. It’s profoundly easy to preach from mount stupid. Detail takes nuance, it comes with changing perspectives. It’s difficult and uncomfortable and requires humility. None of that is cool.

    I hate to spoil your fun, but these dates are always some what wanky. When my grandpa was in school, they told him that there ist still enough cpal for 40 years. When my dad whas in school tey told him that there is still enough coal for 50 Years. My elementry school teacher told me the same. If ypu look it up today, you will find that the coal reserves last for another 80 to 150 years. Resources dont run out. They get more expensive as the reserves dwindel leading to the developement of alternatives.
