MIT Team Develops Temperature-Dependent Color Changing Roof Tiles

As you know, we love featuring ‘green’ and/or environmentally related advances in technology, and here’s another. This time, a team in the Department of Materials Science at MIT have devised a roof tile that changes its surface reflectivity depending on the temperature.

In a nutshell, at low temps, it absorbs as much sunshine and heat as it can, while at high temps, it is more reflective. Fantastic. Nicknamed the Thermeleon, these roof tiles could save 20% on cooling costs.
