Abstract
Technologies such as stealth buoys and underwater gliders need to modify their own buoyancy in order to operate. Strategies such as pumping fluid are typically used to change the device's net volume. This in turn requires a mechanically sophisticated (and consequently expensive) apparatus. This document introduces the concept of a buoyancy engine that exploits the enormous volume and pressure changes accompanying the reversible electrochemical interconversion of water to hydrogen and oxygen gases. Named the Water Electrolytic Transformation (WET) buoyancy engine, this device promises to deliver a new, efficient, and very inexpensive means to control buoyancy in remote sensing and surveillance devices.
