The Multifun team at Delft University from the Netherlands suggested the idea of collecting energy from the natural vibrations of the liner wings during the flight, for which they must be covered with composite leather. Piezoelectric fibers collect energy in special batteries built into the fuselage. After that, it can be used to power the auxiliary on-board systems.
Their opponents from the team Birdport have developed a concept of drones in the role of scarecrows that drive birds away from the runway area. Drones with the help of certain sounds and baits will lead flocks of birds to the side, thereby reducing the likelihood of collision with airplanes.
Team Retrolley from the University of São Paulo (Brazil) attracted the idea of recycling the waste of passenger airliners after the flight. To do this, they developed a special cart, where rubbish will be sorted and disposed of by minimizing the volume of foil, paper and plastic. Liquid waste will also be collected there.
Meanwhile, a system developed at the Northwest Polytechnic University in China suggests using motion detection technology, infrared and visible information to alert pilots and ground workers about various obstacles.
