Ofcourse, the most efficient way to get to England would be sailing.
Ok, that's true

But if you want to get there FAST then you're better off driving or flying then boating, speed boats get crap mileage.

I'd be worried about the energy density of hydrogen, which is pretty low compared to gasoline. Unless some type of substrate method takes off that increases fuel density, planes will either be severely handicapped performance-wise or space-wise.
Yeah, I think that would be the problem. Also, just so we're clear, I don't mean putting a reactor on a plane, but using power generated on the ground to create hydrogen.

hehe, yeah that would be cool. It would really be an experience to take a cruise in a Zeppelin. If it we're affordable I'd love to sign up for that.

Oh, I love flying too. I've nothing against it, but under no circumstances is flying in any plane more environmentally friendly than driving a really fuel efficient car. The raw amount of GHGs released is greater, and they are released higher and so more damaging. Flying is safer and faster though
