Elastocaloric materials exhibit temperature changes under applied stress and could be the basis for an environmentally friendly cooling system if issues with their long term stability can be addressed. Here, the authors design and build an elastocaloric device using evaporation and condensation of a fluid achieving enhanced specific cooling power and long term stability.
