ABSTRACT:
A method and system for preventing permanent deformation during use and storage of encased expandites that constitute a thermodynamic working fluid for use in combination with a thermal fluid in a thermodynamic energy conversion system. The working fluid is made up of thousands of encased expandites, each of which includes a mass having a flexible covering encasing the mass for enabling rapid heat transfer between the mass and the thermal fluid, for enabling the encased expandite to maintain its integrity as a separate object when submerged in the thermal fluid, and for enabling the volume of the encased expandite to change in accordance with the characteristic interdependent relationship between changes in the density, temperature and pressure of the mass when the encased expandite is submerged in the thermal fluid. Each of the flexible coverings has a maximum containing volume prior to becoming permanently deformed. The encased expandites are maintained at a combination of temperature and pressure that is different than atmospheric conditions to thereby prevent the volume of the encased expandite mass from exceeding the maximum containing volume of the flexible cover.
