1. A method for cooling a load using an integrated constitution thermally coupled to the load, the method comprising:
cooling the load below an ambient temperature while the integrated constitution is under sunlight by:
prohibiting, using the integrated constitution, coupling of incoming electromagnetic radiation over solar wavelengths to the load while the integrated constitution is under sunlight; and
generating, using the integrated constitution, electromagnetic emissions in mid-IR wavelengths while the integrated constitution is under sunlight.
