NASA launches projects for eco friendly aircraft

NASA has announced five research projects that may help make planes more efficient and green. 
•    The projects are aimed at shrinking fuel use, reducing aviation’s impact on the environment and quieting noise around airports. 
•    One of these studies will be based on Lithium-Air "breathing batteries” which expel oxygen as the battery is being charged.
•    Those challenges include shrinking fuel use, reducing aviation’s impact on the environment and quieting noise around airports, all at a time when the skies are being filled with an increasing amount of traffic all across the globe.
•    The five study teams selected this year represent researchers from a variety of technical disciplines who work across NASA's aeronautics centers in Virginia, California and Ohio.
•    As NASA considers all options for achieving its research goals related to green aviation during the next decade and beyond, all-electric and hybrid electric aircraft offer promising solutions.
