      Mice are less efficient than helicopters -- whoda thunk?

      I wonder where the Space Shuttle and Saturn V rockets fit on this.

      "Calories per gram per kilometer". Fruit flies are tiny but they need lots of energy to move relative to their mass.

      I don't see trains on this graph. Association of American Railroads claims 436 miles per gallon per ton. In metric, 30,000 calories takes 900,000 grams a distance of 700 km. I'll need a cup of coffee before my eyes are open enough to solve for calories per gram per km.
