Solar Sandwich to Power Future Buildings
Most modern buildings are composed of several layers of materials, each with its own important function: the concrete core supports its weight; the insulation regulates its heat exchange; the facade contributes to its aesthetics. Now, engineers at the Ecole Polytechnique Federale de Lausanne are developing a single building block that does all of that . . . and produces electricity. This new component will provide a sleek alternative to traditional construction materials, and will be lighter, safer, and more energy efficient. [PhysOrg.com, 8 Jun 2012]
