The energy-saving opportunity right beneath our feet | Hessam AzariJafari | TEDxBoston
We focus a lot on the efficiency of vehicles, but not on the roads they drive on. We may be rolling over the biggest energy-saving opportunity in transportation. MIT research shows that how roads are designed and maintained has a far larger impact on emissions than the materials used to build them. A 20% improvement in road smoothness could eliminate millions of tons of transportation emissions. Making U.S. roads 20% more reflective would be equivalent to taking millions of vehicles off the road. A growing field of research aims at applying materials science to infrastructure as a practical and scalable climate tool. Hessam AzariJafari is a Research Scientist at the MIT CEE (Civil and Environmental Engineering) and Executive Director of MIT ec³ Hub, a multidisciplinary team advancing cutting-edge sustainable material research. The group focuses on industrial ecology and construction innovations, working to implement multifunctional cement-based materials through life cycle assessment, technoeconomic analysis, and material flow analysis. AzariJafari is part of team demonstrating the exciting potential of multifunctional cement-based materials with properties that go beyond structural load bearing, such as storing energy or self-heating. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
