is an absorber member 16 the absorber member 16 may be constructed of triangular shaped tubing coated to absorb the visible spectrum of electromagnetic radiation fluid passes through the tubular member 16 for transferring the thermal energy absorbed thereby one problem with the solar energy absorber shown in fig1 is that since the visible spectrum of the electromagnetic waves have to pass through the three layers of glass 10 12 and 14 a certain amount thereof is reflected affecting the efficiency of the overall system another problem with the system is that as the energy passes through the glass layers 10 12 and 14 a certain amount of the energy is absorbed also affecting the efficiency of the system when dust collects on the glass layers 10 12 and 14 this problem is enhanced theoretically in the device shown in fig1 additional glass layers could be stacked one above the other so as to minimize the amount of infrared radiation loss however as additional layers are added such cuts down on the amount of the visible spectrum of electromagnetic radiation passing therethrough to reach the ultimate solar energy absorber referring in more detail to fig2 of the drawings there is illustrated in accordance with this invention an absorber surface constructed of a triangular shaped tubular member 18 the tubular absorber 18 of fig2 is shown schematically and the adjacent layers thereof communicate with each other and the overall configuration.
