A buoyancy engine is a theoretical concept often discussed in the context of alternative energy or perpetual motion machines. The idea revolves around using differences in buoyancy (the upward force that a fluid exerts on an object submerged in it) to create a system that can generate work or energy. The fundamental principle behind buoyancy is that objects denser than the fluid they are in sink, while less dense objects float.
