Abstract
A technique for varying buoyancy of an apparatus includes providing a substrate configured to produce gas on demand when exposed to a liquid, exposing the substrate to such liquid, and capturing the gas produced by the substrate to increase the buoyancy of the apparatus within a fluid. In some examples, the liquid and the fluid contain the same material, such that gas may be produced using fluid already in the environment.
