Hello Stoves;

Jeremy Warfluft was certainly doing some interesting research in 1984.  One
of the stoves mentioned in his document was the Z-stove, developed by the
Hottenroths.  They hold a number of very interesting patents:

Hottenroth, FW Sr.; Jacoby, HD.  1966.  Forced Draft Solid Carbon Fuel
Burning Cooker  US Patent 3,279,452
Hottenroth, FW Sr.; Hottenroth, FW Jr..  1975.  Portable forced draft solid
fuel burning cooker.  US Patent 3,868,943
Hottenroth, FW Sr.; Hottenroth, FW Jr..  1976.  Portable forced draft
cooker.  US Patent 3,982,522 A
Hottenroth, FW Sr.; Hottenroth, FW Jr..  1984.  Compact stove for emergency
and other uses.  US Patent 4,471,751
Hottenroth, FW Sr.; Hottenroth, FW Jr..  1988.  Biomass Stove.  US Patent
4,730,597
Hottenroth, FW Sr.; Hottenroth, FW Jr..  1991.  Portable Stove.   US Patent
5,024,208

Some of their stoves look like modern TLUDs, although I suspect that they
didn't have top-lit operation in mind, but where thinking of burning chunky
fuel with large pore-spaces, which would produce a fire at many levels down
to the grate.

The Z-stove in Warfluft's document was probably an earlier version of the
Hottenroths'1988 patent, http://www.google.com/patents/US4730597

Their 1966 patent looks strikingly like a flattened version of a modern
forced draft TLUD: http://www.google.com/patents/US3279452

Has anyone ever heard of, or see a "Z-stove"?

Cheers,
Julien.
