Concept images reveal how we'll glide across the sky in electric aeroplanes by 2050

Air traffic is set to increase by seven-fold by 2050 and greenhouse gas emissions by four-fold, unless radical changes are made to aircraft.

To combat the problem, aeroplane manufacturers and young engineers have designed conceptual planes of the future, which could be powered by electricity and biofuels, reports the Daily Mail.

Future aircraft could also have innovative wing designs and bodies inspired by nature as well as smarter and smaller computers on board.

The crucial next step towards ensuring the aircraft industry becomes greener is the full electrification of commercial aircraft, according to Ash Dove-Jay, a PhD researcher in aerospace engineering at The University of Bristol.

Such systems could mean zero carbon dioxide and nitrogen oxide emissions, with energy sourced from ‘green’ power stations.'
