But, all that glitters is not plastic - read below

LONDON (AlertNet) - Two British engineers have scooped a global innovation
award for an inflatable concrete tent, designed for rapid deployment in
disaster zones, but aid workers differ on its practical viability.

But some aid officials are not convinced.
'At first sight it looks marvellous,' said Rishi Ramrakha, a logistics
officer at the British Red Cross Society. 'But the real practicalities look
a bit difficult.'
According to Ramrakha, there are several central problems. First, the unit
is too heavy to be carried easily into areas where there might not be access
for aircraft or trucks. The second is the amount of water needed to erect
each tent.
'Where are you going to get 145 litres in a disaster zone?' he asked.
Experts also point out that displaced populations are accommodated in
temporary shelter because they will eventually be encouraged either to go
back to where they came from, or to make homes and a new life in a better
place.
The construction of permanent structures, particularly in conflict zones,
could hamper that process, they say.

Not to mention that a concrete tent is a little more difficult to take
down and move than a canvas one.

But for a quick and semi-permanent outbuilding, I think it might be
interesting to play with. Didn't Bucky Fuller make some of his
domes with concrete covered fabrics?
