If things go as planned, the Aircruise might just be the future’s slowest way to get around. For now, however, the 265-meter-tall airship isn’t a finished product; an announcement the other week billed it as a “visionary transportation concept.” Seymourpowell, the design firm working on the project, and Samsung C&T, the construction company helping to develop the idea, present the Aircruise as a luxury cruise, or a hotel in the sky. The decadent dirigible  would stay in the air using hydrogen and solar power. Since the physics of keeping such a structure afloat require a large volume with little weight, the concept necessitates vast spaces and few passengers: a recipe for luxury designed to “appeal to people looking for a more reflective journey.” Our bet is the design won’t get built anytime soon, but who knows—there’s always a chance it could get off the ground.

Update: The folks at Airships.net are denouncing the Aircruise concept for its proposed use of flammable hydrogen and its un-aerodynamic shape.
