Do you remember what section you found that in the Brittanica? I have an
edition in my office and spent some time without success trying to find the
data you quote.

Is fusion significant because electricity will be cheap (as in for
electrolysis), or is it because fusion is so hot it decomposes everything? If
that is the case, would not fusion power be the cure-all for *all* mineral
extractions?
