1. A system comprising:

  • a tire rim; and

    a pump fixedly attached to the tire rim, wherein rotational motion of the tire rim about an axis allows gravity to move a pump element in a first direction from a first position to a second position to yield a pump stroke, wherein the pump stroke pumps a gas into a volumetric container supported by pressure different from an ambient pressure outside of the volumetric container, the volumetric container mounted to the tire rim.
