air

Now, on an even bigger scale, across the whole of the world, the idea is exactly the same with all of these
air
molecules.
And then, armed with just two laptops and one
air
card, we built a recovery machine.
To make things worse, my grandparents didn't have an
air
conditioner.
This includes everything from the
air
conditioners I so desperately wanted during my summer vacations, to the refrigeration systems that keep our food safe and cold for us in our supermarkets, to the industrial scale systems that keep our data centers operational.
Nearly every apartment in and around my grandmother's place now has an
air
conditioner.
Even though the
air
temperature might be above freezing, say five degrees Celsius or 41 degrees Fahrenheit, the water would freeze.
You've actually likely seen something very similar at play if you've ever noticed frost form on the ground on a clear night, even when the
air
temperature is well above freezing.
How did the water freeze if the
air
temperature is above freezing?
Namely, the
air
that surrounds it.
I'm showing you data here from our very first experiment, where that material stayed more than five degrees Celsius, or nine degrees Fahrenheit, colder than the
air
temperature, even though the sun was shining directly on it.
Over the next year or two, I'm super excited to see this go to its first commercial-scale pilots in both the
air
conditioning and refrigeration space.
As a first step towards that, my colleagues at Stanford and I have shown that you could actually maintain something more than 42 degrees Celsius below the
air
temperature with better engineering.
It was a breath of fresh
air.
And then, once it was in the right place, he got back in the water holding a big knife, and he cut each buoy off, and the buoy popped up into the air, and the cable dropped to the sea floor, and he did that all the way out to the ship, and when he got there, they gave him a glass of juice and a cookie, and then he jumped back in, and he swam back to shore, and then he lit a cigarette.
But unfortunately the words get transformed as they travel through the
air.
For example, planes require more runway for takeoff because the heated, less dense air, provides for less lift.
On one occasion I was doing it, every time I did a point that they didn't like, they actually threw stones at me, and when I did a point they liked, they starting shooting in the air, equally not great.
Well, we also learned that Vasari, who was commissioned to remodel the Hall of the 500 between 1560 and 1574 by the Grand Duke Cosimo I of the Medici family, we have at least two instances when he saved masterpieces specifically by placing a brick wall in front of it and leaving a small
air
gap.
And so we built some very sophisticated radio antennas just for probing both walls and searching for an
air
gap.
And we did find many on the right panel of the east wall, an
air
gap, and that's where we believe "The Battle of Anghiari," or at least the part that we know has been painted, which is called "The Fight for the Standard," should be located.
It was usually too hot, too stuffy or just too smelly, and my father would not let us use the
air
conditioner.
We blast the
air
conditioning the entire way, and we never experience overheating.
In the past, before
air
conditioning, we had thick walls.
Then in about the 1930s, with the advent of plate glass, rolled steel and mass production, we were able to make floor-to-ceiling windows and unobstructed views, and with that came the irreversible reliance on mechanical
air
conditioning to cool our solar-heated spaces.
They give off a lot of heat into the atmosphere, and for some of you may understand the heat island effect in cities, where the urban areas are much more warm than the adjacent rural areas, but we also have problems that, when we lose power, we can't open a window here, and so the buildings are uninhabitable and have to be made vacant until that
air
conditioning system can start up again.
So in early prototypes I built these surfaces to try to see how the curl would react to temperature and possibly allow
air
to ventilate through the system, and in other prototypes did surfaces where the multiplicity of having these strips together can try to make bigger movement happen when also heated, and currently have this installation at the Materials & Applications gallery in Silver Lake, close by, and it's there until August, if you want to see it.
One, it's a sun-shading device, so that when the sun hits the surface, it constricts the amount of sun passing through, and in other areas, it's a ventilating system, so that hot, trapped
air
underneath can actually move through and out when necessary.
And what it basically implies is that, in houses now, we don't need drapes or shutters or blinds anymore because we can sheath the building with these things, as well as control the amount of
air
conditioning you need inside that building.
They breathe through holes in their sides called spiracles, and they bring the
air
through and it moves through their system to cool them down, and so in this project, I'm trying to look at how we can consider that in architecture too, how we can bring
air
through holes in the sides of a building.
