Energy is to be generated with a high degree of efficiency from solar light by means of optical concentrators and absorbers, without the need for suntracking. For that purpose, a tubular solar light collector (2) with a tubular absorber filled with a heat transfer medium has convex-concave lenses (1) arranged next to each other in the direction of the axis of the tube in a sector of a circle which faces the sun and detects the daytime course of the sun for concentrating the solar light on the absorber (3). This arrangement is useful for example for heating water, and when a gaseous heat transfer medium is used, for directly heating rooms. |
