I'd like to see a thermodynamical analysis of this, too. Because when 
you grind down a harddisk, very finely, it's not just that you make it 
into confetti. You also raise its temperature the higher your you go in 
the grinding. Presumably you can reach Curie temperature by friction 
alone.

So do you, and when do you?
