We're still hoping Samsung's final design pushes the envelope a little further than a repositioned camera sensor and a new glossy texture -- we've added a shot of this after the break.

The advantage of this arrangement is that it can be scaled up more easily than a semi-rigid design, since the envelope is not load-bearing.

In addition, the IdeaCentre Q100 and Q110 nettops continue to push the envelope on thin and light design as the world's thinnest nettops1 while extending the entertainment experience with support for HD video on the Q110.

They are based on a non-rigid design, in which the pressure of the helium inside the envelope is used to maintain the airship's shape.

ECONOMIST: Pushing the envelope

So far, the company has built a one-eighth-size prototype to test its design, which consists of a carbon-fibre keel, an envelope made from modern composite materials, half-a-dozen engines, a passenger compartment, and a specially lightened crane.

Larger modern airships rely on a semi-rigid design, in which engines and passenger compartments are suspended from a metal keel that runs along the bottom of the envelope and prevents it from distorting under the load.
