Setting the bar pretty high for airship design is this one from Christopher Ottersbach: Called the Aeolus Airship (named after Aeolus, the Greek wind god) it is designed to be aerodynamic than conventional airship designs, and stay aloft for up to two weeks on a supply of helium and, furthermore, is pedal-powered by the crew of 2-4 people.

That’s about all the tech detail I’ve come across; it’s certainly made the rounds in the past couple of days but no specific website or contact info seems forthcoming.
