> But your power estimates on what a hydrogen fuel cell can do are off by a bit

My estimate didn't assume the ship left the shore with any hydrogen fuel. I (apparently incorrectly) assumed you meant that the ship would generate its own hydrogen during the day from excess solar while it was in transport.

Ah yes, that wouldn't work at all.

If solar cells got effective enough to generate that much power, you’d probably be better off with solar + battery anyhow.
