Aerofoils on fridges

I was at an event in Glasgow yesterday where Williams Advanced Engineering (a spin off from the FI Team business) were talking about a company that had approached them with the idea of fitting aerofoils onto fridges - which seemed mad but had turned out to be a genius idea. By controlling the flow of cold air on supermarket refrigerators a saving of 30% on electricity costs can be achieved and the "cold" aisles are generally about 4 deg warmer. Easy to fit and practically invisible that are now popping up on fridges all over. I'm going to look out for them now.

As an aside; apparently the front wing of a F1 car takes, on average, 2000 hours to design and build and has a life span of 7 weeks or two races before needing to be redesigned and built again.
