This invention relates to a method and to a device for the implementation of said method, for selectively picking up some frequencies of a radiative spectrum, for a first use and, at the same time, to use the residual frequencies for thermal purposes. The method is characterized in that it includes the following steps: • to pick up said electromagnetic radiation; • to induce the reflection of said one or more frequencies using a reflector coloured by colours corresponding to said one or more frequencies; • to receive said one or more frequencies reflected by said coloured reflector; • to convey said one or more received frequencies towards a user device; • to use said residual frequencies for increasing the temperature of said coloured reflector; • to take the thermal energy produced by said coloured reflector. The device (A) is characterized in that it includes: - first means (3), fitted to reflect said one or more frequencies and to absorb said residual frequencies, in such a way to produce thermal energy, said first means (3) being coloured by one or more colours corresponding to said frequencies to be reflected; • second means (5), fitted to receive said one or more frequencies reflected by said first means (3) and to transmit them to a user device. |
