Technology for pollution-free "electric flight" is being evaluated in a number of NASA Glenn Research Center programs. One approach is to drive propulsive fans or propellers with electric motors powered by fuel cells running on hydrogen. 1/5 For large transport aircraft, conventional electric motors are far too heavy to be feasible. However, since #hydrogen fuel would almost surely be carried as #liquid, a propulsive electric motor could be cooled to near liquid hydrogen temperature (-423 °F) 2/5
