However, since the energy provided by CF would for the most part *replace*
carbon based fuel consumption, it is mostly an offset . . .
This all assumes the efficiency of CF is similar to heat enigines, or that
waste heat is used effectively.
I think those are very safe assumptions. It is easier to use cold fusion heat effectively than it is to use other sources of heat such as combustion, because these other sources produce poison gas, and they are much too hot (i.e., there is an impedance mismatch). Also, efficiency is bound to improve in the future. It could hardly be worse than it is now!
As I said, I discussed this in the book in some detail.
