Researchers improve efficiency of human walking (w/ video) (Update)
Humans have evolved to be incredibly efficient at walking. In fact, simulations of human locomotion show that walking on level ground and at a steady speed should theoretically require no power input at all.
Which has a more efficient 'engine': A tuna or a whale?
A large gray whale and a much smaller skipjack tuna each propels itself through water. Which is the more efficient swimmer? It has been difficult to compare propulsion efficiencies of animals of different ...
