What I saw the steam as was a replacement for an electric fan. Most
TLUD units use a fan to get the flow high enough for maximum heat
out. Steam meant no electricity needed.

That is quite possible. Would you (as a person struggling to
survive) trade off a few extra twigs for another 15 minutes to gather
food? I would bet you would rather than not having enough calories
to stay alive. If someone gave me a super-hot stove which took an
extra few twigs, but heated the water in 1/2 the time under those
conditions, I would, and I wouldn't care about pollution one bit.
In a survival situation the extra time has to be traded off against
the extra fuel. A 12 foot high pile of rice husks won't feed me, but
an extra 300 calories might let me survive an extra day.
