Does anyone have any definitive numbers on the efficiency of
transformers?  in particular, the ones on the poles outside the house.
I was having a discussion with a friend the other day and he was
claiming that upcoming improvements in core material would increase the
public power distribution system efficiency by large (10%,20%) amounts.
I was under the impression that the gadgets were already so efficient
that there wasn't that much headroom to play with.  

But I don't have any real numbers.  Who does?
