Transient liquid pressure power generation systems and associated devices and methods

A transient liquid pressure power generation system, comprising:

• a liquid source;
• a transient pressure drive device fluidly coupled to the liquid source to receive liquid from the liquid source, the transient pressure drive device comprising a drive component configured to do work external to the system, a transient wave producing element, and a liquid conduit fluidly coupled to the liquid source, wherein the drive component is located upstream of the transient wave producing element, the transient wave producing element is operable to cause a high pressure transient wave in the liquid traveling through the liquid conduit toward the liquid source to operate the drive component to do work external to the system, and the liquid conduit comprises a first transition surface between a first cross-sectional area and a second cross-sectional area operable to reflect at least a portion of a transient pressure wave in the liquid traveling through the liquid conduit;
• and
• a heat source fluidly coupled to the transient pressure drive device and the liquid source to receive liquid from the transient pressure drive device and heat liquid returning to the liquid source, wherein the heat source utilizes energy from a source external to the system to heat the liquid.
