Why doesn't this render?!

This model, made in Rhino, doesn't have a very high poly count (9,159 faces). It renders when I use a solid material (31 seconds), but if I try to make the fins 50% transparent, the rendering starts up, but takes ages to go anywhere! I can see it starting to calculate the light cache, but it is SO SLOW.

I'm not an expert on this, but what machine are you running on? How many CPUs or cores and how much RAM would be the first relevant questions.

I'm on a quad core machine with 6GB of RAM and I notice a significant slow down in performance when turn on shadows for example. So, it may just be that your model is taking a lot of processing power.
