My 'recycled sail' google alert picked up this story. The truly beautiful images of Christopher Ottersbach's concept air travel vehicle stopped me in my tracks. Aelus, named after the Greek ruler of the winds, is an airship that floats through the air thanks to it's helium filled 'sail' and was designed for travel with little impact to the environment in mind.
The vertical shape and a fold out stand allows landing in many areas far from airports. People can travel to exotic and untouched places without leaving traces. The concept is not about a fast arrival but about sensibility to the environment and traveling.
