Tierr@_de_N@die: Airplane industry can not rely on electrify the whole fleet in the next decades, they must explore further ways to reduce CO2 airplane emissions in order to face the environmental challenges.
»The industry is still growing, so we really need to look at more sustainable airplanes. We cannot simply electrify the whole fleet, as electrified airplanes become way too heavy and you can’t fly people across the Atlantic on electric airplanes – not now, not in 30 years.»»So we have to come up with new technologies that reduce fuel burn in a different way. We’ve been flying these tube and wing airplanes for decades now, but it seems like the configuration is reaching a plateau in terms of energy efficiency.»
