This inflatable structure enables lightweight transportable buildings, which is somehow intriguing:

Inflatable structures (aka airbeams) have developed rapidly in recent times, finding application in a variety of new engineering projects ranging from military tents in Iraq and Afghanistan to antennas in outer space. (...) By changing design parameters, the airbeam shape can be modified for different products. The team guided and matured two weaving and braiding capabilities into a reliable technology with unlimited potential, according to Leighton, and in the process created an economical manufacturing base.

And it seems to be quite robust as attested by this.

Why do I blog this? hum I am just impressed by inflatable structures...
