Or run a deep space probe.
The Voyager spacecraft were run with a thermo-pile heated by a
nuclear core.

  You can increase a wood fire's efficiency dramaticly, by
enclosing it on three sides, with large stones.  Even more
so with a chimney.

Look, just forget it. It ISN'T going to happen commercially. End of story. A
high pressure steam generator driving a turbine like they use in coal fired
power stations is vastly more efficient. Gas Turbines running from natural
gas, better still too. GE hold the record with about 60% thermal efficiency
on those.
