Abstract
Systems and methods for extending life of an apparatus, such as a balloon, using electrolysis. A ballast liquid is carried or harvested and, when desired, is electrolyzed using an on-board electrolyzer to generate lift gas, rather than simply being dumped as traditional ballast. However, the ballast liquid may also be dumped, if necessary. A valve may be provided to enable safe dumping of the ballast liquid. The ballast liquid may be water, a water-methanol mixture, or other suitable ballast liquid. The ballast liquid may be stored in a container associated with the balloon prior to launch or may be harvested from the atmosphere while the balloon is in-flight. Features may be provided to maintain the ballast liquid in a liquid state. The lift gas mixture within the balloon is maintained non-flammable.
