Aeolus Airship can stay in the air 2 weeks

All things that go up must come down. In the case of the Aeolus Airship concept however, they don’t have to come down for quite a long time. The vertically designed helium airship would be able to stay in the air for 2 straight weeks without landing, and can handle a crew of 2-4 people at a time. It’s definitely an interesting concept to look at, and could have some pretty practical uses if it can truly stay aloft for 2 weeks.  We’ll take a ride, please… [via Gizmodo]
