Abstract: A selective radiation utilization apparatus includes an optical filtering device and a modulation device. The optical filtering device transmits one or more selected spectral bands of incoming solar radiation and reflects one or more remaining bands of the incoming solar radiation. The modulation device spatially modulates one of the one or more selected spectral bands or the one or more remaining bands and directs the spatially modulated one of the one or more selected spectral bands or the one or more remaining bands towards a target of illumination.

Abstract: A system is set forth herein which can include a plurality of reflectors adapted to reflect light. The system can further include a plurality of photovoltaic cells. A certain reflector of the plurality of reflectors adapted to reflect light can be adapted to reflect light within a certain wavelength band and can be further adapted to transmit light outside of the certain wavelength band. A photovoltaic cell can be disposed to receive light reflected by the certain reflector.
