    摘要: A radiant cooling system comprises an enclosure, a cooling element and a cooling device. The enclosure includes a first wall that is transmissive of infrared radiation. The cooling element is disposed in the enclosure. The cooling device is coupled to the cooling element. The cooling element provides cooling mainly by radiative exchange. The system promotes cooling by radiative exchange and significantly reduces condensation problems and is compatible with open and enclosed spaces. Thermal losses of cooling power to conductive and convective pathways are significantly reduced. The system comes in a variety of forms including flat, cylindrical and dome-like geometries.

    摘要: A photovoltaic system is described that improves solar energy absorption efficiency by resolving light into constituent colors using dispersive optics. The system reduces a blurring effect of a light beam while ensuring that the system's bulkiness is not increased. The photovoltaic system disperses a focused light beam into constituent colors (spectrum) and provisions for sufficient expansion of the light beam. The photovoltaic system re-focuses the dispersed light beam that results in a reduction of the beam size, while the beam is being exposed to photovoltaic cells that convert the incident light energy into electrical energy.
