Tom Reed can provide some history. I have four of them that we evaluated for Tom in about 1990.

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.
