How efficient is Bicycling? Here is an egg-planation.
A 140 lbs / 62 kg bicyclist go ten miles per hour / 16 km per hour, burns about 25
calories per mile
(1.6 km). One
extra large egg supplies 80
A cyclist can travel about three miles (5 km) on the energy of one egg.
A person walking would require three eggs to go the same distance. (A 140 lbs
/ 62 kg person walking three miles per hour / 5 km per hour, burns about 80
calories per mile / 1.6 km)
A loaded bus requires the equivalent of two dozen eggs for each person it carries three
A train requires the equivalent of three dozen eggs for each person it carries three
A car that gets 12.5 miles per gallon (~31,000 calories per gallon) requires the equivalent of
93 (7.75 dozen) eggs to
carry one person three miles.
Even if you double the miles per gallon (25 mpg) and double the occupancy
(two), a car will still use
the equivalent of twenty-three eggs to make the trip -- more than twenty times a bicycle.
Even a Toyota Prius, getting 50 mpg, loaded with four adult (how
often do you see that), consumes six times the energy per person of as the
bicyclist, for the trip.
FYI: For bicyclists who live on potatoes when they ride, there are about 130 calories in a small potato (1-2/3" to 2-1/2" in dia.) (138.0 grams)
