“A couple of years ago we heard about the MOlecular Solar Thermal (MOST) system, in which solar energy is stored in a liquid medium, then later released as heat. Now, the technology has been applied to a clear film that could be applied to the inside of windows in energy-efficient buildings.
Developed at Sweden’s Chalmers University, the MOST film incorporates a norbornadiene–quadricyclane molecule. This causes the transparent polymer film to take on an orangey-yellow color when not being directly exposed to sunlight.
Once the sun rises in the morning and…”
