Green Airways Flying Saucer Plane Design

Is this green flying saucer plane the eco-friendly plane of the future? It's a design from the CleanEra project, aimed at making air travel more economical (in the environmental sense) by using lighter materials and weird ass shapes. Their goal is to get the carbon usage down to less than 50% of current planes. Whether this is light on the Earth is yet to be seen, it looks like something the Green Lantern would fly in.
