> I think electric aircraft need another doubling or two in specific energy to become feasible, so another few decades

We have plenty of fossil fuel so if most of the world stops burning gas we can run aircrafts on fossil fuels for centuries. Even emissions wont be a problem as cheaper energy on ground can be used to capture green house gases and store them someplace.

My trucker friends loved the electric semi trucks but what they were upset about was the charging time. Every hour the truck is idle you are basically losing money, losing rhythm of driving and so on. I think with aircrafts it is going to be an even bigger issue.

Does anyone know what stops us from building tech where batteries are rapidly switched ?
