Solid state refrigeration requires improvements of magneto-, elasto-, baro-, and electro-caloric materials. In this paper we sketch the potential and challenges for introducing the giant entropy changes associated with ferroelastic phase transformations in practical cooling applications: energy efficiency, effect size, and fatigue behavior. The figure exemplarily sketches a barocaloric cooling cycle.
