370-mile hydrogen-electric seaplane set to clean up island hopping

(as I said I'm clearly no expert about fuel cells)

And separate minor point, while it's pointed out as a novelty, I somehow doubt the composite construction is really targeted at anti-corrosion (I mean it might contribute a little on this front I guess). Corrosion issues in seaplanes are well understood for 50+ years, right? It's for the weight savings mostly.

I wonder if we'll ever see an electric tilt rotor aircraft with huge variable pitch props. Should be much more efficient, but probably also much more mechanically complex...

I've always found this branding a bit weird, but I'm weird, as well, so there's that...

I sincerely wish them luck.

I don't know that much about hydrogen fuel cells, but they seem to be promising. Not exactly sure why they don't get much more love. Maybe there are issues with hydrogen production, so it's not really all that "clean."

Hydrogen fuel cells are just this constant pie in the sky thing. Stop making them and go solve the H infra problem, that’s the barrier.

Aren't there still all kinds of fasteners, brackets, sensors, etc? How much of that is proper 316 stainless vs. materials that will have the traditional corrosion problems? What other mitigations are made on seaplanes?

That's fine, and there's galvanic anodes for the structures that aren't, but it's all the copper wiring and connections that will be a practical problem.

Nothing will be “cleaned up” with hydrogen.
