Abstract
Methods and systems disclosed herein relate to using a rotating flywheel battery in a balloon in a high-altitude balloon network. An example method could include converting, in a balloon, first electrical energy into kinetic mechanical energy. The balloon includes a flywheel battery configured to rotate about a spin axis. The kinetic mechanical energy includes a rotation motion of the flywheel battery. The method could further include storing the kinetic mechanical energy for a finite period of time. Further, the method could include performing, using the flywheel battery, at least one of: i) converting at least a portion of the stored kinetic mechanical energy into second electrical energy; ii) stabilizing at least one motion of the balloon based on the rotational motion of the flywheel battery; and iii) rotating the balloon substantially about a balloon axis substantially perpendicular to the ground surface of the earth.
