Apparatus for the utilisation of thermal radiation having a thermosensitive member, a Fresnel lens (107) for selectively directing thermal radiation onto the thermosensitive member, and a generator means for converting the resulting expansion and contraction of the thermosensitive member into electrical power. The thermosensitive member may be a hollow elongate rod (105) through which fluid may be channelled. The fluid may be salt water and the thermal radiation may be used to transfom the water into steam to thereby desalinate the water. |
