Dive summary:

• A material that researchers at Stanford University report having developed appears to be able to reflect sun's energy so effectively that it might be able to cut energy for cooling by 35% if 10% of a building surface is covered with nanophotonic material.
• The material uses quartz and silicon carbide, and the energy it reflects is at a frequency that assures it will penetrate the layer of greenhouse gases around the globe and not come back down to earth.
• The scientists wrote about their material, which uses reflective and radiative cooling, in the journal "Nano Letters."

Even better, this passive technology mitigates carbon emissions given that air-conditioning units would be obsolete in a building clad in such engineered panels. ...
