It requires looking farther back into where the energy comes from. Humans are rather inefficient at converting calories in carbohydrates into movement. Electric motors are comparatively better at turning electric potential energy stored in batteries to kinetic energy. Keep going this way and you'll eventually reach the efficiency of converting solar power to movement, which is again directly comparable, and electrical systems win compared to biological systems. |
