An energy system operable to generate mechanical energy. The energy system comprises a cluster of elongated energy cells. The energy cells are arranged parallel to each other in their longitudinal direction in a cylinder block means. Each energy cell is operable to generate mechanical energy when a phase change material (PCM) changes from solid phase to liquid phase, wherein the phase change material expands when changing from solid phase to liquid phase. The energy system also comprises a cylinder head means and a cylinder bottom means, both connected to the cylinder block means. |
