The Additive Manufacturing Integrated Energy (AMIE) demonstration, displayed at DOE’s Office of Energy Efficiency and Renewable Energy Industry Day event, is a model for energy-efficient systems that link buildings, vehicles and the grid. An ORNL team worked with industrial partners to manufacture and connect a natural-gas-powered hybrid electric vehicle with a solar-powered building to create an integrated energy system. Power can flow in either direction between the vehicle and building through a lab-developed wireless technology. The approach allows the car to provide supplemental power to the 210-square-foot house when the sun is not shining.
The demonstration also showcases additive manufacturing's rapid prototyping potential in architecture and vehicle design; the car and house both were built using large-scale 3D printers. The 38x12x13-foot building was designed by architecture firm Skidmore, Owings, and Merrill (SOM) through the University of Tennessee-ORNL Governor’s Chair for Energy and Urbanism. It was assembled by Clayton Homes, the nation’s largest builder of manufactured housing. Connecting the house to the 3D-printed vehicle demonstrates the concept of integrating two energy streams, buildings and transportation, which typically operate independently.
