Airless energy return wheel

  Quote: "An object that is sprung requires dramatically less energy to move than an unsprung object." Translation: "I don't know anything about physics." How did this nonsense get posted to Wikipedia?

    The "less energy" is only true for an uneven surface. A normal tire would have to fight against the up/down movement. The sprung tire would act somewhat like a cam and transfer the up/down movement into forward movement.
