As I said, let's say we are simulating airflow over  a fast moving 
object - now normally the fluid dynamics CFM is crap and it is cheaper 
and more accurate to throw it in a wind tunnel.

The wind tunnel is not measuiring data to any high accuracy but its 
using atomic level measurement cells in enormous quantities in parallel.

The problem with CFM is you cant have too may 'cells' or you run out of 
computer power. Its a step beyond 3D modelling where the more triangles 
you have the closer to real everything looks, but its a similar problem .

But a wind tunnel built out of analogue 'cells' might be quite simple in 
concept. Just large in silicon scale.

And it wouldn't need to be 'programmed' as its internal logic would be 
constructed to be the equations that govern fluid dynamics. All you 
would then do is take a 3D surface and constrain every cell in that 
computer on that surface to have zero output.

If I were a graduate again that's a PhD project that would appeal...
