NASA has chosen five new aviation-related technologies that it intends to study intently over the next two years as part of its ongoing Convergent Aeronautics Solutions project, the agency said recently. The researchers will focus on fuel cells, the use of 3D printing to improve electric-motor performance, energy storage in lithium-air batteries, ways to change the shape of a wing in flight, and a new antenna design based on the use of lightweight aerogel.
