Go on, name a machine more efficient at locomotion than the bicycle.
It depends on how you measure it - pick your parameters correctly and a
747 is _remarkably_ efficient. You need to factor in the 10-100 times
faster speeds, the 400 odd people at once plus luggage and freight, and
~10,000km per trip or so before the ~10 tons per hour of fuel use at
cruising speed starts to become a reasonable number though...
400 people traveling in 10,000 km in 100 reasonably efficient compact
cars are going to go through something like 100,000L of gasoline in
100hrs. One 747 will move the same number of people the same distance
for around the same amount of fuel, but it'll do it in 1/10th the time...
How you factor in the 10 times speed increase compared to a car (or,
from the other point of view, the 3600 person hours saved), and quite
how that compares to 400 bicycles (for, what, 1000hrs each?) instead of
100 cars is an exercise left to the reader...
