They allow you to mechanically breathe, mechanically ventilate.

We've seen surgeries for three or four hours to ventilate the patient on this.

They had to intubate her, so they put a tube down her throat and they began to mechanically ventilate her.

And that would be to create a kind of three dimensional bubble a really interesting overcoat that would naturally ventilate, would breathe and would seriously reduce the energy loads.

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 amp Applications gallery in Silver Lake, close by, and it's there until August, if you want to see it.
