An electric car is easy, 2.5 billion electric cars not so much. One electric ocean faring vessel is difficult, but once you can 90,000 is easy. And like I said, 90,000 cargo vessel are using twice the fuel resources of those 2.5 billion cars. That's approx ~56,000 electric cars vs one electric cargo vessal

Just thinking out loud here, but if the main problem with building 2.5 billion EVs is making the batteries, why would that change anything if those 90,000 cargo ships each need 56,000 EV's worth of batteries? I'm sure there's some efficiency to be gained by making larger batteries, but it still doesn't quite add up.

Of course this also assuming a cargo ship is as efficient as a car in terms of replacing the ICE with an electric motor. I've heard the fuel these cargo ships use is some of the worst quality fuel that we have and it doesn't burn well, but it's very cheap in the insane quantities they need.

That's not how scaling works, big is easier, small is harder. Also we'd be replacing 56,000 cars worth of fuel storage on that cargo ship too. We can make non lithium batteries for mass storage, but they're the size of a house, couldn't get one in my car, but something tells me a cargo ship could carry it.
