In an effort to improve fuel efficiency, NASA and the aircraft industry are rethinking aircraft design. Inside the 8’ x 6’ wind tunnel at NASA Glenn, engineers recently tested a fan and inlet design, commonly called a propulsor, which could use four to eight percent less fuel than today’s advanced aircraft.

An example of a grid-scale solar energy project. Thousands of mirrors, called heliostats, direct the sun’s energy onto a receiver, which was built using expertise gained from constructing the space shuttle main engine. The NASA spinoff receiver sits on top of a 550-foot tower. Image Credit: SolarReserve
