Give a designer and aviation geek some time and a pencil, and you might just get something great.

At the very least you'll get something spectacular.

Oscar Viñals, a Spanish designer and aviation enthusiast, has released details, and incredible pictures, of what he is calling the "greenest aircraft imaginable."

Equipped with self-repairing wings, large windows, a vertical takeoff ability and room for 755 passengers, the "AWWA Sky Whale" joins several other outlandish proposals for future aircraft that have cropped up in the last couple of years.

Viñals' design uses hybrid engine technology and "active wings," among other things, to create a plane that, should it ever get built, will not only look great but will be one of the safest and most efficient planes in the sky.
