Aeolus Airship

From Gizmodo:

This oddball vertical airship is designed to stay in the air for a whopping two weeks without landing. It's powered by a crew of 2-4 people pedaling, presumably in an ironic nod to The Flintstones.

The helium airship, named for the Greek god of the wind, is only in the concept stage for now. But it looks like something out of Dinotopia, and the goofy vertical design is surprisingly cool.
