I believe this 93% figure (natural gas) includes all the heat
reclaimation mantioned.  I would question the 99% figure, as friction
and pumping losses are not as easy to reclaim.
One thing under consideration is the use of a catalytic convertor to
wring the last bit of fuel energy out and convert it to heat.  At that
point, the noxious part of the exhaust would be safer to manipulate as
well...
