Next picture. It just popped open. You just touched the thing, and the thing gives its shape right like that. And, you can see, then, your triangulation, and you can see how the webbing is done.

Next picture. There is a man standing on top of it. Just as rigid as steel.

Now, I saw that you could go even further than that. That we could cut out the webs of the triangles, because it was only the triangular forms so that's the way the pattern of the molecules go in.

Next picture. So here is, then, a geodesic made where you only have a plenary chamber of the tubes themselves. And this is the shape it takes. It pops always automatically takes that shape. I want to give you more and more confidence in experiencing with me, I said the reduction to practice, and you'll really learn whether your theories are right or wrong, that's why I've given every kind of a test I can. And it has proven out absolutely superbly. In pneumatics it has to this is the shape it wants to take. And it takes it.

Next picture. Now here I also I've talked to you about delivering whole cities by air, and the in 1927 when I started in on thinking about "dwelling machines" for human beings and mass production "dwelling machines" to live in, environment controls. I then said, "You can't assemble things and move them over the highways, because the railroad bridges would automatically be like a sausage machine and give you that shape that's exactly why the trailers are the shape they are they are allowed only 8 feet wide and such and such a height. So they are extruded by the bridges, and I said "I'm going to have to have some way of delivering the dwelling facilities, the environmental control by air to be transcendental to any bridge or anything like that." So that I got into then I assumed right from the outset, the air delivery of buildings. And I assumed right from the outset that I must meet the most formidable conditions. So my first thoughts, actually, were of installing delivering a ten deck building, which would be used by remember I was in the Navy, and I am doing my thinking the year of the Lindbergh flight. And I came out I was thinking about the Navy strategy of getting across the ocean there would be stepping stones, you would go to several islands. You wouldn't try to do it all in one piece you'd like to make it a little safer.

And they had then, I said "you could fly over the Arctic" because a great deal of the year their water spaces open up. So I planned a building for an aeronautical maintenance crew who would live in the Arctic, and we would have, then, stepping stone flights over the Arctic. And I'd be able to take care of. It had to be a building then, that was so absolutely complete that people just moved in, they didn't have to have any time, they would freeze to death putting it up and so forth.

So I, I went into the study of the this picture is really sad because in the upper right hand corner, there, it should be up on the left here, there is a zeppelin. I had gotten in then to what weight was necessary, using a spine and tensegrity forms of tension webbing and so forth, to make a ten deck building. What weight could I really get it down to to do all the things that we really needed to do and I got down to a weight which I found, in the year 1927, called the scantlings of the design data on the Graf Zeppelin which was about to be built in Germany, were given, and what she could carry, what her useful carrying load would be. I found my ten-deck building could be carried by the Graf Zeppelin.

Therefore, go back to that picture again, if you don't mind, please I had then the this was a cartoon and in the upper left hand corner cartoon I had the zeppelin with the ten-deck building suspending horizontally below the zeppelin and it looks just like a very large cabin on the zeppelin. And the zeppelin drops a bomb to make a crater, and then they lowered the building down into the crater hole you can see the crate hole in the middle top picture, and they go down then, and they fill it in again, planting it like a tree. And it had all it's integral sewage disposal and everything, and the thing went down in the bottom there.

At any rate, I knew I was not going to be loaned the Graf Zeppelin and so forth, but I knew that I was actually working within logistical limits, that it was a feasible matter to talk about delivering a ten-deck building by air. And I said, by giving myself the worst condition you could possibly have at the North Pole, this would be the test I've got to have some limit conditions. There would be no building department at the North Pole to say you can't do it. It is very interesting, the first use of my geodesic domes, were exactly that, got to be the Radomes for the Defense Early Warning System up at the northern end of Thule and so forth. Where nothing else would work.

At any rate, there is your 10-deck building, and the 10 deck building is done with you see all this wire, wire work and had pneumatic floor triangles and so forth. It had, like ships, built-in booms on the upper right hand side you'll see, there is an enormous aerial, there is also a vertical wind mill of the Flettner type, and there are built in arms like the booms on ships for loading. And, if you'll remove my figure from the picture for a moment. Look at the lower left hand corner and you'll see a bathroom being hoisted on the cable by the boom to be brought in the building. You bring everything big into the building from outside you just open the building on the side, just swing things in instead of trying to bring things through the central elevators, which is really a very poor way to do. But if you load it the way you can the ship, will just swing the sides of buildings open and swing big things in, and then close them up again lock them up. At any rate, this is how the whole thing was designed, and I want you to see that it did have, right from the outset, integral use of wind power, and it's tank in the base had all plans for using the human wastes and so forth the energies that were in them, because as of that time, it had already been proven at the chemical engineering section of the farm engineering of the University of Illinois at Urbana, that the amount of methane gas in the human family waste or farm family would be enough actual of energy to run the farm machinery at the time. So that, incidentally, one little man took them seriously, and went into the development of a little automobile in 1929, and the UN I went to a meeting of the UN last year, they asked me to come down there, and this little man has been running his automobile on the methane gas from the family ever since 1929 he was no trouble at all.

At any rate, I want you to get, these early 1927 plans for the Dymaxion House and buildings, I want you to understand what is in there. You had to be totally responsible for all the needs of the human beings that are going to be in there, and you had to be able to deliver and take away.

Next picture. I said that, because this picture and the one picture before can you go back one picture of the air lift? In l954 which is quite a long time after 1927, United States Marine Corps the Head of the Aviation Logistics
