Hexayurt LazinessImpatienceAndHubrisVinayGuptaOfTheHexayurtProje547

0:00 - 0:03

This is an open hardware project.
0:03 - 0:07

And it’s an open hardware project with no electronics to speak of.
0:07 - 0:16

There are a few electronics. Let me give you the electronics.
0:16 - 0:20

So, I wanna point this out, it's the direction open hardware is going.
0:20 - 0:22

You wanna take one of those and pass them on?
0:22 - 0:23

These is some lights.
0:23 - 0:26

I don’t think we need that light. It's probably okay without it.
0:26 - 0:28

[audience: alright for the video]
0:28 - 0:29

Ok, cool.
0:29 - 0:34

These things here are hexayurts, and these ones are Burning Man.
0:34 - 0:37

And you can see, they are just, they are little houses, right.
0:37 - 0:41

They are, sort of, housing-pod-things.
0:41 - 0:45

And they’re incredibly easy to make.
0:45 - 0:49

We'll just, right, take a look at them.
0:49 - 0:52

I want to suggest that this is an example
0:52 - 0:55

of open hardware taking a different direction.
0:55 - 0:58

And this is the direction I think open hardware is going,
0:58 - 1:00

that it’s becoming more and more like software,
1:00 - 1:04

where you just casually hack together physical artifacts.
1:04 - 1:06

And my speciality happens to be housing and infrastructure
1:06 - 1:08

and sustainable developement,
1:08 - 1:10

but you can do anything this way.
1:10 - 1:13

So, let’s think about this,
1:13 - 1:16

if we take laziness and impatience and hubris,
1:16 - 1:18

instead of being for software,
1:18 - 1:21

as a way of thinking about hardware. Right?
1:21 - 1:24

What’s the lazy, impatient, you know, ambitious way
1:24 - 1:27

of doing hardware systems. Right?
1:27 - 1:29

So, these lights that I’m passing around,
1:29 - 1:32

have not been formally announced as open hardware yet,
1:32 - 1:34

but they are 7 dollars, right?
1:34 - 1:36

Look at that thing. 7 dollars!
1:36 - 1:38

[Audience: 7 dollars!] 7 dollars!
1:38 - 1:40

Now, the difference that that makes,
1:40 - 1:41

as an open hardware project,
1:41 - 1:43

you can sell these as open hardware
1:43 - 1:47

incredibly cheaply in the developing world, right?
1:47 - 1:50

And, you know, that's not the direction we typically think of open hardware.
1:50 - 1:53

Open hardware typically is microprocessors and all the rest of that stuff.
1:53 - 1:55

No, there’s a different direction here.
1:55 - 1:59

So, laziness, hubris and impatience, right?
1:59 - 2:08

150 square-meters of buildings built by 6 guys in 2 days.
2:08 - 2:11

Does that sound useful for CCC, maybe?
2:11 - 2:13

[Audience: How many?]
2:13 - 2:25

7 buildings: 1, 2, 3, 4, 5, 6, 7 buildings.
2:25 - 2:29

Large, 150 square-meters between them, 6 guys in 2 days.
2:29 - 2:33

And it wasn't really very hard work. Right?
2:33 - 2:37

This is a radical breakthrough building technology. You know.
2:37 - 2:39

This place is Maslowtopia,
2:39 - 2:41

you can see in the bottom corner,
2:41 - 2:42

you've got the google street view,
2:42 - 2:46

you know, the map, they do a high-res picture of Burning Man every year.
2:46 - 2:48

This was a huge camp with these units.
2:48 - 2:51

I didn't even know these guys were building this thing.
2:51 - 2:52

I just, after the event, I saw some pictures of this.
2:52 - 2:56

They didn't ask me how to do anything.
2:56 - 2:57

[Audience: They didn't ask your permission?]
2:57 - 2:59

No, they didn't ask me how to do anything:
2:59 - 3:02

they just downloaded the plans and built the damn things. Right?
3:02 - 3:04

So it's an open hardware project
3:04 - 3:07

in massive full-scale replication
3:07 - 3:08

because it's really, really simple.
3:08 - 3:14

And the simplicity, right - lazy, impatient, hubristic - right,
3:14 - 3:16

the simplicity is what allows the idea spread.
3:16 - 3:19

So how do you make a hexayurt?
3:19 - 3:21

You need this very broad tape.
3:21 - 3:24

You need to know how to make this thing called the tape anchor,
3:24 - 3:25

which is like a, you know, like a knob,
3:25 - 3:27

where you've got a special way of using rope to make a fastener.
3:27 - 3:31

So the tape anchor is a special way of using tape to make a fastener.
3:31 - 3:35

And then you need these polyiso panel material
3:35 - 3:35

that they sell at any babas [?],
3:35 - 3:38

and that's all there is to it.
3:38 - 3:39

It's a really really simple system.
3:39 - 3:42

And all of this stuff you would look on the internet,
3:42 - 3:45

you can find the references for how to do these things.
3:45 - 3:46

Hexayurt in wood.
3:46 - 3:51

So, this really shows like how the thing is put together.
3:51 - 3:55

The wall is just a whole 1.2 x 2.4 panel.
3:55 - 3:59

And this is the standard size for all industrial sheet materials:
3:59 - 4:06

cardboard, plastic, wood, metal, sandwich panels,
4:06 - 4:07

can you think of anything else?
4:07 - 4:10

It's just the standard industrial size for materials.
4:10 - 4:12

The roof pieces are half of that size.
4:12 - 4:15

So you take a piece, you cut in half. Right?
4:15 - 4:18

If you happen to be making it in plywood,
4:18 - 4:23

you can take, you see these wooden blocks, light coloured sections?
4:23 - 4:25

So that's just a piece of 2-by-4 [wood]
4:25 - 4:26

that's been cut with a 30 degree angle on it,
4:26 - 4:30

and you screw the building together with those.
4:30 - 4:34

And you're done!
4:34 - 4:38

So, I mean, that's, thank you very much, that's the talk!
4:38 - 4:41

[audience laughs]
4:41 - 4:44

So, ok, there's a little more to it, right?
4:44 - 4:48

But, you know, I want to make the point that, actually, you know,
4:48 - 4:53

that picture is pretty much all there is to know about the basic hexayurt.
4:53 - 4:54

It's that simple.
4:54 - 4:58

If you happen to be making it using, you know, this kind of material,
4:58 - 5:02

you need to get tape and you need to know how to make a tape anchor.
5:02 - 5:04

If you're making it out of this kind of material,
5:04 - 5:05

you need to know how to make these little wooden blocks,
5:05 - 5:08

you need to know how to cut that much plywood and screw it.
5:08 - 5:11

But really this is all there is.
5:11 - 5:13

And then there's all the stuff [$$5:14$$ you worried] on top of it.
5:13 - 5:17

But the basics are so incredibly simple, that right now, in 5 minutes,
5:17 - 5:20

you've all aquired the basic knowledge of how to make hexayurts.
5:20 - 5:21

And if you had to figure out the actual details
5:21 - 5:25

to make them out of any given material,
5:25 - 5:28

you know, you're smart people, it's not going to take you very long.
5:28 - 5:30

It's an idea that spreads incredibly quickly.
5:30 - 5:33

So, this is the first hexayurt that was ever built.
5:33 - 5:36

You can see the solar panel that drives the cooling system.
5:36 - 5:38

The swamp cooler.
5:38 - 5:42

It's 1.2 meter squares that is made of, Burning Man 2003.
5:42 - 5:46

God that's a great party!
5:46 - 5:49

So, this is the configuration space of hexayurts, right?
5:49 - 5:52

You’ve seen the basic ones in two materials.
5:52 - 5:55

Geometry, the material choice and the construction technologies
5:55 - 5:58

are the 3 big variables.
5:58 - 6:03

So, this is the different kinds of hexayurts that exist:
6:03 - 6:04

that's a six-foot hexayurt
6:04 - 6:07

stretch hexayurt
6:07 - 6:11

pentayurt, which has a nice steep angle on the side [?] for dealing with snow
6:11 - 6:12

standard hexayurt
6:12 - 6:13

stretch hexayurt
6:13 - 6:15

double stretch
6:15 - 6:19

double-height double-stretch, alright,
6:19 - 6:21

and that's your configuration space.
6:21 - 6:24

Obviously you could connect the damn things together any way you like.
6:24 - 6:27

$$6:26$$. Big hive [worm?] type things pretty easy to do.
6:27 - 6:31

[Audience: make a giant "C" out of that]
6:31 - 6:34

Yes, you could make a giant "C" out of that pretty easily.
6:34 - 6:37

You could make a bunch of small Cs. I mean ...
6:37 - 6:40

[audience: "Does anybody see where this is going?"]
6:40 - 6:43

(laughs)
6:43 - 6:45

If you have enough hexayurts, you know,
6:45 - 6:50

you could make a big C in any font you liked.
6:50 - 6:52

[Audience: Now, what do we need to represent this form
6:52 - 6:54

that you see on the window behind you?]
6:54 - 6:59

One of those? I if you've got 4000 people coming, right?,
6:59 - 7:03

at 5 people per hexayurt gives you enough hexayurts
7:03 - 7:05

to do realize quite a high-res version.
7:05 - 7:07

[Audience: do you know that the original size of c-base
7:07 - 7:09

has a diameter of a mile?]
7:09 - 7:14

It's about the size of Burning Man. Entirely reasonable.
7:14 - 7:18

[332 people]
7:18 - 7:21

That's fine. You wind up with 400 hexayurts,
7:21 - 7:26

that's a 20x20 pixel array, you'll be fine!
7:26 - 7:28

So, other ways of constructing these things, right?
7:28 - 7:30

This is a kind that you make instead of with panels, with tubes.
7:30 - 7:33

So you have a frame like this.
7:33 - 7:37

The advantage this has over the standard geodesic dome
7:37 - 7:40

is there are only 2 connectors,
7:40 - 7:43

there are only two section pieces,
7:43 - 7:46

so the triangles are full length,
7:46 - 7:51

and the hexagon around the top are missing a few inches per piece,
7:51 - 7:52

a few centimeters per piece.
7:52 - 7:54

So it's only two components.
7:54 - 7:57

And the walls are vertical,
7:57 - 7:59

so you could take two of these units and connect them directly together
7:59 - 8:02

with no connection problem.
8:02 - 8:04

$$8:02$$ So you can actually have very modular pieces,
8:04 - 8:06

and the materials are sized in such a way
8:06 - 8:08

that you can make the fabric cover really easily.
8:08 - 8:10

This is the fabric cover instructions.
8:10 - 8:12

And you could make zero waste cover,
8:12 - 8:15

if you want to go down the route of having frame.
8:15 - 8:19

We're also at the point, cos the project started by 2003,
8:19 - 8:22

and by 2011 we've also got new designs that came from other people.
8:22 - 8:25

This is a thing called the h13
8:25 - 8:28

and you can see it's still using full sheets and half sheets.
8:28 - 8:31

And there's this corner thing you do at the front
8:31 - 8:34

that gives you a full 2.4 meter entryway.
8:34 - 8:36

Cos the conventional hexayurt has a low entry way,
8:36 - 8:38

which is a pain in the arse.
8:38 - 8:40

This one has a high entry way so it's easy to walk in and out
8:40 - 8:42

and it's only one more panel.
8:42 - 8:47

This is one that was made for a party for Canada in the middle of winter.
8:47 - 8:50

It's actually quite a clever piece of engineering.
8:50 - 8:55

It's 2 sheets of thin plywood sandwiched around some insulation foam
8:55 - 8:58

and you see the yellow band around the side?
8:58 - 9:01

It's the webbing strap that you use in a truck to hold the load on it.
9:01 - 9:02

That's being used as a tension rim
9:02 - 9:04

to stop the building fall into pieces.
9:04 - 9:07

So probably you'd open that strap
9:07 - 9:07

and you take the building down again.
9:07 - 9:11

[Audience: Pure genius!]
9:11 - 9:14

Right? But, you know, that stuff is like 20 dollars a strap
9:14 - 9:18

and it's a breaking strain of 8 tons, so why not use it for construction?
9:18 - 9:23

Laziness, hubris and impatience!
9:23 - 9:25

Can you imagine a lazier building for the middle of Canada?
9:25 - 9:28

Could it possibly have more impatience?
9:28 - 9:34

$$9:30$$... building materials … strap off a truck, dude!
9:34 - 9:35

Then, take a look at this structure.
9:35 - 9:37

This is longer on the hubris side.
9:37 - 9:39

So there's your standard hexayurt in the middle,
9:39 - 9:43

and then there's these two dirty grey big domes.
9:43 - 9:48

Look at the size of these things. 45 square meters for 30 sheets worth of material
9:48 - 9:53

so the ratio of material to surface area:
9:53 - 9:55

Each board is 3 meters,
9:55 - 10:02

it needs 30 boards so you get 90 meters worth of materials for 45 meters of space
10:02 - 10:04

{10:00} The thing is basically a perfect hemisphere.
10:04 - 10:08

And it only uses whole boards and half boards.
10:08 - 10:11

So all those shapes are 1.2 x 2.4 meter boards
10:11 - 10:15

either cut in half or used full. Right?
10:15 - 10:21

Woo! Suddenly you're beginning to talk about really big construction
10:21 - 10:23

with zero waste and no screwing around.
10:23 - 10:27

And because all of these hexayurts are using the same components,
10:27 - 10:29

imagine you've got a standard kit of parts,
10:29 - 10:32

and you rearrange the buildings you need for a given event,
10:32 - 10:34

now we need lots of small ones, now we need some big domes.
10:34 - 10:38

It's all the same connectors, it's all the same panel sizes.
10:38 - 10:42

It's a flexible architecture. Interesting things happen.
10:42 - 10:43

And I want to make a point:
10:43 - 10:47

The reason that Buckminster Fuller didn't get to this stuff is that
10:47 - 10:49

Buckminster Fuller was optimising for the wrong thing.
10:49 - 10:52

He was optimising for minimum mass
10:52 - 10:55

which is of course what you want in a space station.
10:55 - 10:59

If you've got a mass-dependent drive technology in zero-g,
10:59 - 11:01

mass is your critical factor.
11:01 - 11:06

But, if you're operating on the ground in the gravity well $$11:04$$
11:06 - 11:08

with standard materials from an industrial supply chain,
11:08 - 11:10

you’re looking for a different optimisation.
11:10 - 11:12

You don't want minimal mass, you want minimal waste.
11:12 - 11:14

And that means using a different branch of maths,
11:14 - 11:16

in this case it's concave tiling.
11:16 - 11:19

So it's the same mathematics as for things like Penrose tiles
11:19 - 11:22

to figure out wether you can get it tight.
11:22 - 11:25

We get back to the hubris part:
11:25 - 11:27

I think if we'd had this technology in the 1960's,
11:27 - 11:29

the hippies would have won.
11:29 - 11:34

Because the problem with geodesic domes was that
11:34 - 11:37

the damn thing's really hard to build and would always leaked!
11:37 - 11:42

So all the communes failed because they couldn't afford to build houses! Right?
11:42 - 11:44

[Audience: (laughs) Interesting theory!]
11:44 - 11:46

Places like Drop City, all of the houses leaked,
11:46 - 11:48

everybody was unhappy,
11:48 - 11:50

people just decided to go back to the suburbs
11:50 - 11:51

because they wanted a house that didn't leak.
11:51 - 11:53

I'm telling you: this is the technology of victory.
11:53 - 11:56

This is how the freaks take over the Earth.
11:56 - 12:00

You know, look at the size of that dome, right?
12:00 - 12:02

There are plans on thingiverse
12:02 - 12:04

to download laser-cut plans to make these domes,
12:04 - 12:08

if you just look for "nearodesic" or "hexayurt".
12:08 - 12:10

Look at how big [compared to] the standard hexayurt.
12:10 - 12:14

It's huge. You should $$12:11$$ build four of them [?]
12:14 - 12:18

You know, this notion of having a single panel repository,
12:18 - 12:19

where you can reconfigure the buildings if you want,
12:19 - 12:20

using the same basic components,
12:20 - 12:24

I think that is the way that this stuff is gonna go.
12:24 - 12:27

I don't know how to make the panel connectors yet, to make it possible,
12:27 - 12:29

but when we figure out how to do that,
12:29 - 12:33

then imagine just being able to rent from some central service
12:33 - 12:37

you know, 27 panels, for 4 domes you're going to use for the weekend
12:37 - 12:39

and then give them back on monday morning.
12:39 - 12:40

Configurable building.
12:40 - 12:43

So we've covered the geometry.
12:43 - 12:46

Everybody agrees pretty large configurations based on geometry?
12:46 - 12:47

Wait till we get to the materials.
12:47 - 12:51

[sound-engineer: Please, get closer to the microphone. Thank you.]
12:51 - 12:54

So these are the materials we've done already.
12:54 - 12:56

And it's basically anything we could get our hands on,
12:56 - 13:02

you take a look at it, "Yeah, I could make a hexayurt out of that".
13:02 - 13:05

the connection technology changes a little depending on your material.
13:05 - 13:08

Ok, you know, this one is heavy, we're gonna use bolts.
13:08 - 13:09

That one is light, we're gonna use tape.
13:09 - 13:12

Maybe we could make some more metal connectors.
13:12 - 13:15

You just sort of look at your material, you figure out your connector,
13:15 - 13:18

and you apply the connector to the material, and there's your hexayurt.
13:18 - 13:20

We haven't done very much with metal,
13:20 - 13:23

because it's expensive and it's a pain in the arse.
13:23 - 13:26

We haven't done very much with structured insulating panels,
13:26 - 13:28

because they are expensive and it's a pain in the arse.
13:28 - 13:31

The really hot thing we haven't done yet,
13:31 - 13:35

that I'm really eager to do, is ferrocement or spray concrete.
13:35 - 13:36

You know concrete sprays?
13:36 - 13:37

[Audience Yeah]
13:37 - 13:38

Ok, so, imagine you -
13:38 - 13:39

[Audience: No, I don't know]
13:39 - 13:42

Ok, so you put concrete in a big sprayer and you spray it.
13:42 - 13:43

[audience laughs]
13:43 - 13:47

It turns out to be a lot harder than that in practice.
13:47 - 13:48

In fact there are companies that come and
13:48 - 13:50

spray your things with concrete for you, right?
13:50 - 13:52

Your neighbour has a car that's really annoying you,
13:52 - 13:54

you come, you tell 'em which car and you have it sprayed.
13:54 - 13:55

[audience laughs]
13:55 - 14:01

So you build one of these hexayurts out of this light-weight foam material.
14:01 - 14:03

You spray with concrete on the outside,
14:03 - 14:05

you spray with concrete on the inside,
14:05 - 14:08

now you have a highly insulated concrete permanent building.
14:08 - 14:11

And it's only 1 cm of concrete inside and out,
14:11 - 14:13

so the building is still relatively light,
14:13 - 14:17

so you can do things like put hexayurts on top of existing buildings. Right?
14:17 - 14:20

Now, you know, this has potential, nobody's done it yet.
14:20 - 14:27

Actually, so, there's something about printing designs on corrugated plastic.
14:27 - 14:28

Highly printable materials have [?] corrugated plastics.
14:28 - 14:31

You can print anything you want outside the hexayurt.
14:31 - 14:35

So imagine taking a picture of the place,
14:35 - 14:37

doing the 3D projection to know exactly
14:37 - 14:39

what you've got to put on each side of the hexayurt,
14:39 - 14:41

and then printing a camouflaged hexayurt
14:41 - 14:42

which is completely invisible
14:42 - 14:43

because it looks like you are looking straight through it.
14:43 - 14:47

All of this is possible.
14:47 - 14:49

Ok, construction techniques.
14:49 - 14:52

[audience: That only works from a single point of view.]
14:52 - 14:55

Well, maybe, the eye is very lazy,
14:55 - 14:57

so it's posible that we'd get something that works from multiple points of view
14:57 - 15:01

and it looked a little bit wrong as you walk along one side
15:01 - 15:03

and you wouldn't really notice.
15:03 - 15:06

{15:00} But I don't know: nobody's tried it so we've got to do some experiments, right?
15:06 - 15:10

So, there are lots of different ways of doing this stuff
15:10 - 15:12

depending on whether you want to be just a one-off unit,
15:12 - 15:14

whether if you want it to be folding,
15:14 - 15:15

whether you want it to be folding as a single component,
15:15 - 15:20

again it's a big configuration space.
15:20 - 15:22

This is a completely folding hexayurt unit
15:22 - 15:26

that was built by some German army dudes in Stuttgart for an exercise.
15:26 - 15:29

[Audience laughs]
15:29 - 15:31

Oh, yeah, the military love this hexayurt.
15:31 - 15:33

They are super into them.
15:33 - 15:36

Which is a long story.
15:36 - 15:40

So, you know, that building thing is a single module
15:40 - 15:45

and I've got some video in here I can show you the video in a second.
15:45 - 15:49

Or if you just go to http://hexayurt.com/fold there's all the folding hexayurts there.
15:49 - 15:52

This a different kind of folding hexayurt
15:52 - 15:55

so this one is much bigger and it's two components:
15:55 - 15:58

The triangles are the roof and the walls are the walls -
15:58 - 16:01

rectangles are the walls.
16:01 - 16:03

So the whole roof is this single star thing
16:03 - 16:08

and then you pull this star-thing open and there is your roof.
16:08 - 16:11

And this happens to be built inside a gigantic geodesic dome in Eindhoven.
16:11 - 16:16

$$16:11$$ Which is built ... might remember ... Red Cross ...
16:16 - 16:20

So, this is kind of where I see the future of this whole project, right.
16:20 - 16:23

Because it's open hardware it's beginning to be comercialized.
16:23 - 16:25

There is a resale market in America for hexayurts.
16:25 - 16:28

So people build them for Burning Man and sell them afterwards
16:28 - 16:33

and the market value seems to be 500$ a unit.
16:33 - 16:36

Getting to this point where you can spray the damn things and make them permanent,
16:36 - 16:38

it's gonna be the way to do this.
16:38 - 16:41

That opens up a whole new set of terrain.
16:41 - 16:45

Also rural squatting, so you take a van,
16:45 - 16:47

you put 12 hexayurts in the back as a foldup
16:47 - 16:47

You drive out to an abandoned farm.
16:47 - 16:50

You live in them for 3 months.
16:50 - 16:52

Somebody comes and servest you a court order and says you must leave.
16:52 - 16:56

You put them back in the van, and you drive 30 miles down the road.
16:56 - 17:00

It's all [?]
17:00 - 17:02

This is also a really important detail:
17:02 - 17:05

Ultraviolet light eats everything.
17:05 - 17:09

So the big advantage of the hexayurt is that we use a foil surface.
17:09 - 17:11

You know these foil surface panels.
17:11 - 17:14

That stuff will last a really long time in the outdoors.
17:14 - 17:17

So the ability to have rigid buildings that last a long time
17:17 - 17:19

because they've got an appropriate UV protective surface
17:19 - 17:22

is really key to getting this stuff to work,
17:22 - 17:23

if you want multi-year buildings.
17:23 - 17:28

Because UV will ruin any kind of plastic eventually.
17:28 - 17:31

And this thin shell concrete thing, you know, that's gonna come.
17:31 - 17:33

So that's the hexayurt part.
17:33 - 17:36

Let me show you two other cool things.
17:36 - 17:42

Cheap ID is a barcode and crypto-based solution for managing digital identites.
17:42 - 17:44

You take a passport.
17:44 - 17:47

You generate some digital signature that you have seen the passport.
17:47 - 17:49

You put the digital signature on a piece of paper
17:49 - 17:52

together with a jpeg of somebody's face
17:52 - 17:54

And then you have an anonymous digital identity
17:54 - 17:57

that's still $$17.57$$ [pa??] by nation-state credentials.
17:57 - 17:58

What you would do with that, I don't know.
17:58 - 18:01

But you’re smart people you'll find a use.
18:01 - 18:03

Got be some use for it, right,
18:03 - 18:07

like ID-cards for things where you want people to get in
18:07 - 18:08

but you don't want necesarly to reveal anything
18:08 - 18:11

other than the fact that somebody’s allowed there.
18:11 - 18:17

And there's this thing which is the dartboard of death.
18:17 - 18:20

ODeath.
18:20 - 18:30

[audience: Yeah I perfectly understood that part,
18:30 - 18:32

you can also call it the dartboard of doom]
18:32 - 18:35

Dartboard of doom.
18:35 - 18:38

(voices acting like Lord vader)
18:38 - 18:40

Let me explain this before we get silly.
18:40 - 18:45

There's only six ways people die:
18:45 - 18:48

too hot, too cold, hunger, thirst, illness, injury.
18:48 - 18:51

And the services that protect you from dying of these things
18:51 - 18:54

are split through different levels of society.
18:54 - 18:58

Individual person, household, village,
18:58 - 19:04

community or city, region, country and world, right.
19:04 - 19:07

So you have this notion of a stack of interlocking services
19:07 - 19:08

that provides the essential services.
19:08 - 19:11

This is a design tool that I've used when I was thinking about
19:11 - 19:13

doing things for war refugees camps.
19:13 - 19:15

So it's a way of figuring out that we have actually
19:15 - 19:18

covered out all the essential needs within the concept of core technologies.
19:18 - 19:22

So this is sitting out there, again, this is under the creative commons license.
19:22 - 19:25

It models everything up to and including state failures.
19:25 - 19:28

There is no software support for it yet, so we do it all with spreadsheets.
19:28 - 19:32

Spreadsheets suck.
19:32 - 19:35

So this is a really useful analysis tool,
19:35 - 19:37

and its the kind of thing that we are tryin to begin to think
19:37 - 19:39

to develop some kind of software to support.
19:39 - 19:42

If anyone’s interested in this stuff, give me a shout.
19:42 - 19:47

So, that was it.
19:47 - 19:49

I'll turn off recorders and I'll take questions?
19:49 - 19:51

[voice: Yes, sure]
19:51 - 19:53

You want to see the folding videos?
19:53 - 20:00

OK, hang a second.
20:00 - 20:04

I don't think I have put this machine on the network.
20:04 - 20:52

(silence)
20:52 - 21:04

There's the crap animation GIF
21:04 - 21:07

Have you seen this by the way?
21:07 - 21:15

It's a 15 euro USB chargeable, awful awful horrible quality loud-speaker.
21:15 - 21:18

But they are incredibly loud and they're dirt cheap.
21:18 - 21:25

Now I can show you, let's see...
21:25 - 21:28

So this is the German army dudes video.
21:28 - 21:40

(silence)
21:40 - 21:52

{21:50 or so} What? No! Go away!
21:52 - 21:55

[video: Shall we try again (laughs).
21:55 - 22:00

One of these days, we'll get just the right angle
22:00 - 22:02

and we’ll understand how to make it work,
22:02 - 22:06

and once we understand why, then it will be easy.
22:06 - 22:11

Understanding counts, understanding counts.
22:11 - 22:29

open-close, one-two-three]
22:29 - 22:34

It’s called polyiso, polyiso.
22:34 - 22:35

[So, what makes it so hard?]
22:35 - 22:36

It's a cheap insulation board.
22:36 - 22:42

[I don't know either, that's why I'm asking you.
22:42 - 22:52

Ok, so let’s give that a try.
22:52 - 22:58

Yes, oo, ok, you got it.
22:58 - 23:01

Now, what did we do that made it easy that time?
23:01 - 23:03

[mumble] oposite ends [?]]
23:03 - 23:06

This is the red cross, one,
23:06 - 23:09

The prototype we did for the Red Cross.
23:09 - 23:15

Sorry it's an animated GIF, there's video but it's really slow.
23:15 - 23:22

This is a smaller size that someone did at Burning Man.
23:22 - 23:53

(silence)
23:53 - 24:09

And that's -
24:09 - 24:17

{24:10} [Roof herd - retreat! Not through the puddle.
24:17 - 24:17

Your feet are gonna get wet.
24:17 - 24:19

Go around, go around!
24:19 - 24:21

Oh, what are we gonna do! Okey!]
24:21 - 24:26

So this one we had material that was 3 meters by 1.8 meters.
24:26 - 24:30

So we modified the design slightly and wound up with this huge structure.
24:30 - 24:33

It's like 24 or 30 square meters in size.
24:33 - 24:34

Just enormous.
24:34 - 24:45

[wall ... 1, 2, 3, 4, 5 ... that will be the problem ...]
24:45 - 24:52

There's the sixth side! [wall ... Okey?]
24:52 - 24:57

[Does that look about right? Looks about right to me.
24:57 - 24:59

Ok, so, roof folks!
24:59 - 25:01

Now, here we're gonna have a bit of a problem
25:01 - 25:05

because we don’t want the bottom of the roof to get wet, do we?
25:05 - 25:10

So we're gonna get everybody and we're gonna open the roof in mid-air. Ok?
25:10 - 25:12

Does that sound remotely possible?]
25:12 - 25:14

So this is another clever thing that we've learned.
25:14 - 25:17

Which is what I call "gang carry".
25:17 - 25:19

So, if everybody involved in the lift is carrying
25:19 - 25:23

less than about 10 kilos, maybe 15,
25:23 - 25:26

you get very very fine motor control of the lift,
25:26 - 25:28

regardless of how heavy the object is.
25:28 - 25:31

So you can actually take a hexayurt that's made of plywood, right?
25:31 - 25:35

It's 12 sheets of plywood, 3/4 of an inch thick,
25:35 - 25:39

and you can lift it with 4 people or 3 people on each side,
25:39 - 25:41

so you got a gang of 18-25 people doing the lift,
25:41 - 25:44

and you can just pick them up and walk with them
25:44 - 25:45

because it's got so many people lifting it
25:45 - 25:47

that each individual person is only taking a little weight.
25:47 - 25:52

And that turns out to be a important technique light-weight construction.
25:52 - 25:54

And it's very hard to get people to do
25:54 - 25:57

because everybody expects lifting a heavy object to be hard work.
25:57 - 26:02

And the idea of using so many people to lift it the heavy object becomes easy.
26:02 - 26:12

People can’t get their heads around until they've done it.
26:12 - 26:14

Everybody's looking confused: "shouldn’t this be heavier?
26:14 - 26:19

What are we supposed to be doing here?"
26:19 - 26:20

I and then you start moving
26:20 - 26:32

and instinctively everybody tends to coordinate and it just sort of works.
26:32 - 26:40

(mumble) See, we‘re on ice here. It's quite -
26:40 - 26:42

[Now comes the tricky part.]
26:42 - 26:45

So people have to feel off the front [?] run around,
26:45 - 26:49

go inside, then take the [?] back again.
26:49 - 26:51

It is very slow, very careful movement.
26:51 - 26:53

But you can do it even in plywood,
26:53 - 27:04

even if the material is really heavy, it still works.
27:04 - 27:08

[Audience: I see. No door?]
27:08 - 27:15

No, you don’t do windows and doors in hexayurts, so we say.
27:15 - 27:17

So, it’s a kind of ritual,
27:17 - 27:20

putting the roof on,
27:20 - 27:21

taping the roof in place,
27:21 - 27:22

and then cutting the door.
27:22 - 27:26

We kind of do if for fun, but it’s a really nice moment.
27:26 - 27:28

[audience: ???]
27:28 - 27:38

If you've got a space station you can use transport ... fine.
27:38 - 27:41

[I have a question.
27:41 - 27:50

for the geodesics stuff ... material]
27:50 - 27:53

I’ll tell you what:
27:53 - 27:55

when I turn off the cameras and recorders
27:55 - 27:57

you guys be comfortable and ask me questions,
27:57 - 27:59

then we’ll take questions.
27:59 - 28:02

So, thank you!
