So I was getting into what I called the "fog gun" experiments and I want to point out to you coming back to our experience with hydraulics, we have been thinking about hydraulics and pneumatics. The hydraulics were non-compressible, very much more dense than are the gases. Therefore, when we get to trying to be economical with water and cleaning, you could get into a needle point shower, get where the kinetics of you get high pressure but very fine little droplets, and then because it is non-compressible it really is a little bullet, and you get to a point where the needle-point shower will break your skin, and that is as far as you can go. And still you're not getting very much greater very much economy with your water.

What I found you could do would be to take compressed air, and atomizing water into the compressed air, that the air itself then, very much less weight than the water, then the air being also pneumatic and so forth, it could really penetrate your pores, and under great pressure without hurting you at all. You could have really very powerful pressure of air on your skin and it doesn't hurt at all. And I found that it could get into the pores, being really finer molecules than the water molecules, so you get into the pores and if I atomized some water and went in with it there could be a scavenging out of the pores and bring just really float the dirt away. So we went in for such experiments and you've seen human beings cleaning buildings, a great operation going, and it looks like they're using steam up there it isn't. It's highly very high compressed air with water atomized in it. And it is cleaning that building just beautifully, doing just what I said. And if you take one of their kind of guns, you might think it would really hurt, hurt your hand it doesn't hurt you. It might make your arm go like that, but it does not break the skin. So that we got into experiments of that kind at the Institute of Design in Chicago, and we went in for all kinds of study of the different kinds of dirt that occurred around Chicago, and we finally arranged to, we took a lathe, a machine tool lathe, and organized a camera, microscope and camera lenses looking at your hand with a great deal of light, so that your hand would not jerk and so forth we were able to make very beautiful enlarged photographs of the pores of what your skin looks like with dirt on it. And you take a picture of your hand, just the dirty first, and it looks like one thing, but it is completely different when you see it enormously enlarged. There will be literally little hunks lodged out here on the mountain top and so forth, and you can really see how this thing could really work, so we got into studies, then, of all the types of dirt that were known in the total Chicago area, that you might get into there. There are many types you can really classify those.

And, incidentally, a team of the students at the Institute of Design in Chicago went out and interviewed dermatologists in Chicago. In the first place we went to some of the local hospitals, we got names of what were considered the best dermatologists in Chicago, and they called on them, and everyone of them said the worst thing you could have for your skin is soap. So, that was worth paying some attention to, we felt, and so if you could get away of cleaning our skin without use of the soap, it could be very, very excellent, and we found we could.

This came then to problems of different types of guns that you would use, and your supply. In cleaning those buildings they have enormous big engines going and very big compressors and so forth. And what would be the minimum that really would work in your home? Where you could take a bath for an hour out there in a room where you don't have any drainage because there isn't anything to drain. How you could really give yourself a very beautiful massage because this also massages the skin very well.

So that we got to the point where we discovered between the Institute of Design, and later on at the Yale project, that it did require quite a high pressure. The usual automobile filling station where they have air compressors and tanks and so forth go up only to about 200 pounds pressure, and this needs to be at greater than 200 pounds. It does not really work well until you get it over 200 pounds. So this isn't just something you can do with any compressor at all, you really have to have some good apparatus the right apparatus. We found that the Ford Motor Company had developed a special gun for their air compressor where they clean engines, a greasy dirty engine comes in and its cleaned at no time at all with the gun, so that is the same idea, the same air compressor with a little water atomized going into it.

At any rate, I now know that it is highly feasible to do that, and for that reason I have not done much about that bathroom. But that bathroom that you saw you might be interested to know, I had designed it for polyester fiberglass. The art of polyester fiberglass had not advanced to the point where it was a practical matter to manufacture more than just single pieces around the end of W.W.II in the aircraft industry. It had not yet advanced enough, it was not until two or three years later that you began to get a polyester fiberglass of room temperature setting where we could get into the making things such as the polyester fiberglass boats and so forth which have all come along. Really the first of my polyester fiberglass realizations are in the Radomes for the Air Force, and we will come into talking about those in just a little bit here.

But, it is interesting, the bathroom that I designed, and really very much as I designed it, almost off my drawings and patent drawings. And, incidentally, most patent drawings are not the way your working drawings are, but in the case of my bathroom I did use the working drawings to produce the patent drawings, and they are, if you want to look at that patent it is really quite an interesting one to look at. The bathroom that I did design is now being manufactured in West Germany, and is getting into real mass production. The American plumbers plumbing manufacturers and so forth have not yet started moving, they have been bothered by it, so that the Crane Company has on Park Avenue in New York, they have a little room, but they are still taking their fixture, their own fixture and just fastening it to the walls, so they are not really getting into what this really means. But when you get into the polyester fiberglass, absolutely continuous, realize the cleaning capabilities, it is a lovely room to work in, and you'd find it very, very pleasant as a bathroom.

But, I'm quite sure we're going to be able to go much further, and I also do not want to lose those wastes and so forth, so I think we are in for very new apparatus. It has been extremely interesting to me, going to architectural school after architectural school around the world, and I find that the students are very enthusiastic. I've never been able to get the school to literally go into how do we develop the packaging toilet. We should be having a packaging toilet we package our foods inbound, so we might as well package it coming outbound. It is just exactly as easy, and I found that and I did develop, and made a model of a toilet that had plastic sheets in two rolls, and the two sheets then come to the seat, so you're sitting on absolutely clean pressed plastic, and then the plastic goes together and there is a heat sealer so it then makes into keeps coming out in bags like a sausage machine, and so there is no gas escaping, and this goes off into a dry packaging, and get your dry packages filled up and they're all clearly marked and so forth with red marking, or whatever it is, and then you seal it up, so these very valuable chemistries can go off where they are supposed to.

I also point out to you, when Nature takes a terrific amount of trouble to separate things, as for instance our liquids and the solids coming out of us, it is preposterous to put them back together again, so it is quite easy then to develop your apparatus in ways that the liquids and the solids do not get mixed up, but it has been, I say, it is seemingly strange to me, whether it is MIT, places where they should, they have, they say, we have engineering, we have all kinds of hydraulics, we know exactly what the frictions are in pipes, and so forth, but and then we have sewage disposal big sewage disposal plants that just cities will buy, but nobody going into direct research to see what this really means. At your own home, really at the site. And it is something that really could be engaged in very, very readily, and there is just no nonsense about it.

But I am quite certain then, I have been pleased that my bathroom has gotten into mass production, but I consider it to be completely obsolete in relation to what we can really do in the way of cleaning yourself, and the way we ought to be really saving and packaging these very, very valuable chemistries.

Now, I'd like to have my first picture tonight. Remember I said I got into grand strategy where I was only going to work on the enclosures, the environment controls, at making, considered the mast became a fat mast, and got into my going back to my mathematics. Remember I had my mathematics for a very long time, and the first actual use of my tensegrity geodesics and so forth was in the development of the map which I published in LIFE MAGAZINE in 1943 when I got into the great circle grids using the vector equilibrium as the base at that time, and later on using the icosahedron as the base, and this particular picture that's going back to our those are the 25 great circles of the vector equilibrium, and those are the 25 great circles that all go through the 12 points of tangency, spheres in closest packing, those are the total number of railroad tracks in Universe that can by which energy can go from here to there throughout go on and on in space.

And this is, I was unable to find in the pictures that I saw, going back in my slides, I do have a beautiful slide taken in it was published in SCIENCE MAGAZINE, a picture by SCIENCE MAGAZINE in 1947-48, of the first picture ever made of an atom itself, and it is just this same picture. It is really astonishing they are the same picture! It is mildly, if you had some foreshorting of certain lenses wide angle lenses, you can make things you're looking at a little wider at the center. The picture, the lensing effect in their electron microscope they used, were somewhat that way so the square section is a little more open than the one I just showed you, but it tends to have a highlight there is white right in the front there, where you can make out these same 25 great circles in complete evidence.
