“Same reason your car isn’t electric drive - it’s inefficient.”

How much more efficient is it to try to send power through an 18-speed gearbox? I know transmissions have been engineered to the point that the amount of losses through them is so low that it sounds like they’re violating the laws of physics to do it, but generators and electric motors are also extremely efficient.

I still don’t really understand why trucks aren’t diesel-electrics like locomotives are. And as impractical as a hydrogen infrastructure is, I still say it makes way more sense than a battery-electric long-haul semi that probably needs to waste at least half of its load capacity just to carry its “fuel”, even with the…
