(15,909 posts)...demanding some of those creature comforts, there are many, many tons of relatively undemanding cargo just sitting there, going along for the ride.
It would be interesting (though not at all practical) to figure out the potential energy efficiency of transporting people in a very non-luxurious ocean-crossing passenger boat, something just barely above the old "steerage" form of travel. You'd still have to provide and transport at least a week's worth of food for each person (for something like an Atlantic crossing), handle washing clothes, transport the weight of the beds (or cots?) they'd sleep in, provide bathing and toilet facilities, provide heating and/or air conditioning for the long duration of the trip. Even stripped-down cross-ocean travel might have a hard time beating an airplane for efficiency.
