My understanding is that electric airplanes are much quieter but batteries do not have a high enough energy density to make an electric airliner with more than very short range.
I wonder if it would be feasible to make some kind of hybrid that uses electric engines for takeoff and landing and regular jet engines for the rest of the flight?
- slaymaker1907 3y agoLargescale use of electric planes still seem like sci-fi for the time being, but you did get me thinking that airships would likely produce a lot less noise pollution than planes.
