The Paris air show is over with not too tangible green progress. The IATA targets that I blogged before were a good start for the aviation industry to think about ways to make this pollutive industry more earth-friendly, but little concrete has been done. Airbus did host an idea competition which surface some neat ideas. The winner was from the University of Queensland in Australia, with their proposal for usin of the castor plant to develop the first ever single plant-based high performance composite materials for aircraft cabin components. That's nice, but somehow one would think that the CO2 from making those cabins is nothing compared to the CO2 produced when flying those cabins. Maybe I'm wrong.

Another idea that I thought was HOT, came from the Stanford University. Their proposal is for military and cargo planes to fly in a V formation during long-haul, reducing air resistance. The group of students who produced this idea took it from migrating birds who use the V formation to save energy. Another succesful case of Nature 2.0.
