It is very kewl to come up with an energy-efficient vehicle like the Hy-Bird, but even better to design one that is recyclable. Roland Cernat’s Oriens Glider combines “an ecological energy concept and sustainable materials, with an organic design language and bionic inspired details.”

Translated, this means a frame of a lightweight flax bio-compound and a body of polycarbonate. The wings have photovoltaic cells and its electric motor has a propeller that retracts when gliding. A fuel engine and generator make the plane a hybrid. Cernat’s prototype was so impressive it recently won the Lucky Strike Junior Designer Competition.
