I was under the impression that boating was the most efficient form of transport available. While boats operate in a liquid (draggy) environment, they are the slowest and "densest" transporter of goods. What they lack in efficiency they make up in volume. This doesn't apply to the QM2, but goods shipping in general.

Ofcourse, the most efficient way to get to England would be sailing.

In the 1950's, the Airforce flew a B36 Peacemaker with a reactor onboard. It didn't power the aircraft, but that was the eventual intent.

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.

I'd be more interested in the return of the Zeppelin. The ultimate marriage of hydrogen and aviation.
