<p>A solar energy device comprises a concave reflector (1) for reflecting incident solar radiation to a focus and an energy collector (4) located at said focus. As the angle of incidence of the solar radiation changes during a day, the focus is always able to move along a path over the collector, either by the collector being of a specific shape or by movement of the collector. In one embodiment, the collector includes a honeycombed or filamentous structure which absorbs radiation by multiple internal reflections. <IMAGE></p> |
