Thermodynamics of a model system where a group of cold charged particles locally confined in a volume V{sub P} within a warm plasma of temperature T and fixed volume V (V{sub P}<<V) is presented. Various thermodynamic functions of the model e.g., Helmhotz free energy, internal energy, entropy, electrostatic pressure of charged particles are calculated from first principles. In the homogeneous limit, an equation of state for the ES pressure of charged particles is derived and the internal energy is shown to consist solely of the thermal energy of the back ground plasma. Finally, the direct conversion of plasma heat into mechanical work is demonstrated via a Striling like engine cycle involving ES isothermal compression of plasma electric fields.
