This is pretty cool as a test bed of what's possible for oceanic transport… solar + wind + hydrogen fuel cell to power a boat.https://jalopnik.com/hydrogen-is-a-bad-car-fuel-but-its-the-perfect-boat-fu-1841435502 …

so for boats this would mean a flatter design? - more solar / wind surface area - maybe slower speeds?

iPhones currently don't make current economic sense to be on boats because the capital density that's held in inventory as it crosses the ocean is immense. So for high value products renewable naval cargo transport can have a market & you can pressure brands to do it

For a hydrogen ship, would you use fuel cells + electric drive, or an internal combustion engine driving the propellor shaft?

I have a proposal in to ARPA-E to do a really high efficiency, high power density fuel -> energy converter that’s simple and cheap, maybe 10x power density of fuel cells and 10x lifetime, lower cost. I’d just use that. I’ll dm you the concept paper
