This issue is examined first for waves at the surface of a liquid, and second for quantum vacuum electromagnetic waves, both in relation with a one-side-open rectangular structure whose interior embodies a large number of parallel reflecting plates. Using known results about the Casimir-like effect and the original Casimir effect for parallel plates, we explain why and how such rectangular hollow structures should feel net oriented forces. We briefly describe real systems that would allow testing these theoretical results. %K Casimir Effect and Analogs %K Vacuum Energy %K Propulsion Drive %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=50603
