The actual mass that will be fused is in the noise...due the difference
between chemical and nuclear energy.  One source is that the mass ratio for
the fuel is 10^7 to 1.  So, to replace the 4 trillion metric tons of oil
burned every year, we'd use up 40,000 metric tons of deterium and tridium,
and have, roughly, the same mass of neutrons and helium as a result.  The
first is a number that actually matters on a world scale; the second isn't.
