This artist's concept image released by NASA on June 17, 2016 shows NASA's X-57 Hybrid Electric Research Plane. With 14 electric motors turning propellers and all of them integrated into a uniquely-designed wing, NASA will test new propulsion technology using an experimental airplane now designated the X-57 and nicknamed Maxwell. This artist's concept of the X-57 shows the plane's specially designed wing and 14 electric motors. NASA Aeronautics researchers will use the Maxwell to demonstrate that electric propulsion can make planes quieter, more efficient and more environmentally friendly. / AFP PHOTO / NASA Langley/Advanced Concepts Lab, AMA, Inc. / Handout / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / NASA Langley/Advanced Concepts Lab, AMA, Inc." - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS HANDOUT/AFP/Getty Images
