Works for me.  I was merely pointing out that the trick worked because ambient 
air could be used to cool the compressed air.  But, as has been said, it's a 
nit and a tiny one at that.  The ideal, as used in blast furnaces, is preheated 
_and_ compressed air.

I'm not in the Brighton area, though I did post a story about being stopped by 
the police from tackling an incline in bad weather because "only 4WDs are being 
allowed through".  That was in Saltdean, which is about three miles from 
Brighton to the east.  I'm actually around 70 miles due north of London, 
between Kettering and Wellingborough - for those who have detailed maps.
