Here is an eggplanation: A cyclist burns about 25 Calories per mile. One large egg supplies 80 Calories.
A cyclist can travel about three miles on the energy of one egg:
A person walking would require three eggs to go the same distance:
A loaded bus requires the equivalent of two dozen eggs for each person it carries three miles:
A train requires the equivalent of three dozen eggs for each person it carries three miles:
A car that gets 12.5 miles per gallon requires the equivalent of seven dozen eggs to carry one person three miles:
Even if you double the miles per gallon and double the occupancy a car will still use the equivalent of twenty-one eggs to make the trip -- more than twenty times a bicycle.
