    Not sure if you’re aware but we’ve had electric buses and trains for well over half a century. We don’t need them to carry long range batteries. We have them in Europe and even in some places in North America. Batteries haven’t been needed for electrifying public transit for a very long time. In fact some of the first public transit was electric. Some places just choose the cheapest upfront option instead of spending a bit more on infrastructure in order to realize environmental and efficiency benefits.

    As for planes, yes probably. Although I’m not sure whether there’s a viable route to electric planes that goes through batteries or whether that use case would necessitate synthetic fuel.

      even without external electricity you don’t need batteries, there were perfectly functional buses in the 60’s that used flywheels to store energy. And i believe technology has advanced ever so slightly in the 60 years since then…
