  This study explores strategies to improve engine efficiency through
innovative materials, design concepts, and alternative energy sources. It
highlights the use of nanomaterials and surface engineering to create
hydrophobic or other types of surfaces for harnessing entropy-gradient forces.
Additionally, it discusses the potential of information-burning engines and
quantum-based propulsion systems. The manuscript emphasizes the
multidisciplinary nature of engine research and its potential to contribute to
a sustainable and efficient future.
