Which portion of the transport sector do you think is the most difficult to electrify aviation or maritime? (self.electricvehicles)

Now that we have electric semi-trucks propping up all over, which is the next area for clean transport to expand into?

Aviation by an order of magnitude. Batteries are nowhere near the energy density of kerosene, so there’s a lot more weight, that doesn’t diminish during flight. Charging in tight turnaround times.

Pure safety - if a plane needs to make an emergency landing it can purge the fuel tanks. It can’t drop a massive solid battery. Fuel fires in flight can be killed off by stopping kerosene flow to the engine. It would be the fuel source itself which is on fire with a battery, and again no way to get that away from the cabin. Developing a fully fire-resistant battery would be essential.

Psychological factors - a roaring engine feels safer. A whisper quiet plane will be very disconcerting for most passengers initially.

Are you kidding? Quieter transport sounds like a blissful improvement to me.

EVs have a greater rate of motion sickness reports than ICE cars, now add another couple of axes of motion.
