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.
The inventors, Peter Brewin and William Crawford, say they saw a need for
the structure given the inadequate protection provided by tents in the
aftermath of disasters such as the Pakistan earthquake.
'With shelter and medical facilities it is possible to rebuild shattered
communities from day one of a crisis,' they said in a statement.
The tent, made from fabric impregnated with concrete, can be put up by an
untrained person in 40 minutes. It takes 12 hours for the concrete to set,
but once done, the tent can last for up to 10 years.
The two designers, both 26, developed so-called Concrete Canvas during an
industrial engineering course at the Royal College of Art in London. Their
efforts were rewarded on January 26 at a ceremony in New York with the
presentation of the top prize at the Saatchi & Saatchi Award for World
Changing Ideas.
Media reports say the invention has attracted interest from the United
Nations and several international humanitarian agencies.
JUST ADD WATER 'If this was available now, we would buy 10 today,' Monica
Castellarnau, a programme director at M'decins Sans Fronti'res, was quoted
as saying by Wired News. Its combination of ease of assembly with durability
has also drawn praise.
The logic of Concrete Canvas is simple. Each unit ' weighing 227 kg (500
lb), making it light enough to transport by plane or truck - comprises an
inflatable plastic inner bubble, wrapped in the treated fabric and packed in
a plastic sack.
To deploy the tent, the sack is first filled with 145 litres (32 gallons) of
water, which is absorbed by the cloth. The sack is then cut open, the tent
is unfolded and the plastic bubble is inflated. The canvas then moulds
around the bubble and sets to form the solid infrastructure of the tent.
The finished shelter covers some 16 sq meters (172 sq feet) of floor space
and the cost per unit is estimated at '1,100 ($2,100).
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.

It's heartwarming that you're worried about OT posting something that
actually has to do with homes in AHR.

'Where are you going to get 145 litres in a disaster zone?' he asked.

That was my first question. My second is "how do they do the doors and
windows? My third is "I've seen this sort of thing before" in Puerto Rico,
I believe, or at least the same sort of building techniques. I recall
someone describing the difficulties involved with all concrete homes and
they were intense.

Used in places like Pakistan I'd imagine they'd become permanent slums. Way
back when (when we were still friends with Quaddaffi Duck) the company I
worked for used to ship flight simulators and spare parts in those big
Sealand containers. They would never come back because Libyans would take
them and turn them into instant houses. And we're worried about them?

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?

I remember years ago the Marine Corps experimenting with structures whose
main characteristic was inflation.

The structure - as I recall a 12x12' dome - came in two boxes. The first
contained a balloon in the desired shape and an air compressor. The second
largish box contained some spray-on foam.

After the "tent" was inflated, the air compressor was hooked up to the foam
machine and about a foot of expanding foam (think Great Stuff) was slathered
over the plastic bubble. The foam set up rather quickly and doors could be
cut with a saw.

Think igloo.

The Marines discarded the idea.

Doesn't have to be clean, potable (drinkable) water.

You don't think they already live in permanent slums there?

The video says the tent is inflated first then saturated with water.

The video method seems to make more sense since I can't see how a
folded up tent is going to absorb water evenly.

What happens if it rains for few days as the concrete is setting?

Probably nothing. Concrete can be poured and will cure under water.
I did that with a very small irrigatin dam. Had to put the concrete
down a big pipe or it would mix with too much water on the way down.

disaster zones, but aid workers differ on its practical viability.
The inventors, Peter Brewin and William Crawford, say they saw a need for
the structure given the inadequate protection provided by tents in the
aftermath of disasters such as the Pakistan earthquake.
'With shelter and medical facilities it is possible to rebuild shattered
communities from day one of a crisis,' they said in a statement.
The tent, made from fabric impregnated with concrete, can be put up by an
untrained person in 40 minutes. It takes 12 hours for the concrete to set,
but once done, the tent can last for up to 10 years.
The two designers, both 26, developed so-called Concrete Canvas during an
industrial engineering course at the Royal College of Art in London. Their
efforts were rewarded on January 26 at a ceremony in New York with the
presentation of the top prize at the Saatchi & Saatchi Award for World
Changing Ideas.
Media reports say the invention has attracted interest from the United
Nations and several international humanitarian agencies.
JUST ADD WATER 'If this was available now, we would buy 10 today,' Monica
Castellarnau, a programme director at M'decins Sans Fronti'res, was quoted
as saying by Wired News. Its combination of ease of assembly with durability
has also drawn praise.
The logic of Concrete Canvas is simple. Each unit ' weighing 227 kg (500
lb), making it light enough to transport by plane or truck - comprises an
inflatable plastic inner bubble, wrapped in the treated fabric and packed in
a plastic sack.
To deploy the tent, the sack is first filled with 145 litres (32 gallons) of
water, which is absorbed by the cloth. The sack is then cut open, the tent
is unfolded and the plastic bubble is inflated. The canvas then moulds
around the bubble and sets to form the solid infrastructure of the tent.

Well, when I heard the version where "How do it know?" is used, the

The term used was, shall we say, a bit more racially descriptive.

I chose to remove the racial overtones in both the description of the
speaker and in the punchline.

'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.

The article says "To deploy the tent, the sack is first filled with
145 litres (32 gallons) of water, which is absorbed by the cloth. The
sack is then cut open, the tent is unfolded and the plastic bubble is
inflated"

The video says the tent is inflated first then saturated with water.

The video method seems to make more sense since I can't see how a
folded up tent is going to absorb water evenly.

What happens if it rains for few days as the concrete is setting?- Hide quoted text -

Probably nothing. Concrete can be poured and will cure under water.
I did that with a very small irrigatin dam. Had to put the concrete
down a big pipe or it would mix with too much water on the way down.

How does it mix with too much water on the way down but not mix with
too much water once it's actually down?

As the dumb jock once said about a Thermos keeping hot stuff hot and
cold stuff cold:

"How does it know?"

You gave the dumb jock too much credit, he actually said "How DO it

Well, when I heard the version where "How do it know?" is used, the
term "dumb jock" wasn't used to describe the speaker.

The term used was, shall we say, a bit more racially descriptive.

I chose to remove the racial overtones in both the description of the
speaker and in the punchline.

Dang, the White dumb jocks hang out with the Black dumb jocks and they
all wind up sounding alike. Stop being so Politically Correct, it's
silly. One of my darker skinned cousins said something so profound and
funny to me years ago that I'll never forget. "Heck man, dey be stupid
White peoples too!" ^_^

And the blonde, who used her new Thermos, take to work two
popsicles and a cup of coffee.

How many disasters happen in deserts?

http://www.google.com/search?q=water...disaster+zones

Click the above link and educate yourself. I'm a little too busy to do it
for you. I'm married to a retired Army logistician. Water can be awful
hard to come by in a disaster area, especially an earthquake zone where
pipes break and water towers collapse. It does NOT have to be in a desert
by any means. There are three things that are part of every disaster relief
package. Water stations, generators and temporary housing. There are
entire US Army manuals devoted to the subject. Google around, I'm sure
you'll find information about it.

That was my first question.

Doesn't have to be clean, potable (drinkable) water.

Used in places like Pakistan I'd imagine they'd become permanent
slums.

You don't think they already live in permanent slums there?

Osama had a nice $1M compound in a very nice neighborhood in Pakistan. Not
everyone lives in slums in Pakistan, India or in many places in the third
world, contrary to your assertion. Wealthy neighborhoods suffer the same
kind of earthquakes that poorer ones do. The fear of relief agencies is
that emergency housing would cause people not to move back to their original
towns or rebuild their original housing.

Emergency housing is almost always erected on someone else's land, not the
land of the occupants of that shelter and that can cause serious disputes.
In India such relocation has resulted in many deaths as rich farmers, who
often own the land emergency shelters are built on, hired men to displace
the people they see as squatters. As you can imagine, those squatters fight
hard to stay because they usually have no place to go. So that's why
experienced aid workers might see a problem in the concrete shelters.

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.
The inventors, Peter Brewin and William Crawford, say they saw a
need for
the structure given the inadequate protection provided by tents
in the
aftermath of disasters such as the Pakistan earthquake.
'With shelter and medical facilities it is possible to rebuild
shattered
communities from day one of a crisis,' they said in a statement.
The tent, made from fabric impregnated with concrete, can be put
up by an
untrained person in 40 minutes. It takes 12 hours for the
concrete to set,
but once done, the tent can last for up to 10 years.
The two designers, both 26, developed so-called Concrete Canvas
during an
industrial engineering course at the Royal College of Art in
London. Their
efforts were rewarded on January 26 at a ceremony in New York
with the
presentation of the top prize at the Saatchi& Saatchi Award
for World
Changing Ideas.
Media reports say the invention has attracted interest from the
United
Nations and several international humanitarian agencies.
JUST ADD WATER 'If this was available now, we would buy 10
today,' Monica
Castellarnau, a programme director at M'decins Sans Fronti'res,
was quoted
as saying by Wired News. Its combination of ease of assembly
with durability
has also drawn praise.
The logic of Concrete Canvas is simple. Each unit ' weighing 227
kg (500
lb), making it light enough to transport by plane or truck -
comprises an
inflatable plastic inner bubble, wrapped in the treated fabric
and packed in
a plastic sack.
To deploy the tent, the sack is first filled with 145 litres (32
gallons) of
water, which is absorbed by the cloth. The sack is then cut
open, the tent
is unfolded and the plastic bubble is inflated. The canvas then
moulds
around the bubble and sets to form the solid infrastructure of
the tent.
The finished shelter covers some 16 sq meters (172 sq feet) of
floor space
and the cost per unit is estimated at '1,100 ($2,100).
But some aid officials are not convinced.
'At first sight it looks marvellous,' said Rishi Ramrakha, a
