The system discussed consists of a solar collector lined with small metal canisters filled with a high temperature phase change material (PCM), lithium fluoride salt. The canisters are small enough to fit comfortably in the palm of one's hand and there are a hundred or more of them. A heat transfer fluid, an inert gas such as helium or neon, circulates through the pipes that pass through the metal canisters and carries heat away to turbines, generators, etc. The continual melting and refreezing of the PCM smears out the delivery of the solar energy to the transfer fluid, and hence, to the heat engines beyond. The motivation for using a PCM based thermal energy storage system is that a properly sized such system can store and deliver energy over a narrow temperature range near the melting point of the PCM, thus avoiding extreme temperature variations.
