The future of aircraft design

NASA is collaborating with Boeing on a project to improve the sustainability of aircraft design, as part of its efforts to reduce fuel consumption. The $1.15 billion project aims to build and test a more fuel-efficient version of the Boeing 737, which currently accounts for nearly half of all domestic flights in the US.

Finnish engineers have created a small robot that can fly

Engineers at the University of Tampere in Finland have succeeded in creating a robot that is unique in more ways than one. They have created a 4-millimetre machine that can take off and fly using solar energy and a gentle breeze.

Aviation in its current form is not sustainable. The emissions associated with it are staggeringly high compared to the number of people or goods it can carry. The only argument for large (passenger) transport planes is speed, and of course the lack of alternatives. However, the return of airships, which flourished in the 1920s and 1930s, could provide a sustainable and stylish answer to the latter challenge.
