text: A new ultralight door architecture nets a 42.5% weight savings compared to a current production door-and that's enough to put this lightweight concept in an enviable position. “This lightweight door module has a great opportunity to be commercialized. It's not just high-tech. It's also at the right cost,” said Reuben Sarkar, Deputy Assistant Secretary for Transportation, Energy Efficiency and Renewable Energy at the U.S. Department of Energy.
