'thab' stove by liz to
canadian designer liz to has repurposed unwanted wire hangers from north america as an opportunity for remote communities to build their own stove.
the 'thab stove' is a template based on the portable dung stove used by tibetan nomads, created through a weaving of
wire hangers to produce a vessel-like framework. this design can then be filled with stones and boulders to fabricate -
from inexpensive rudimentary materials - a workable cooking stove that reduces the amount of smoke produced from burning fuel,
reduces cooking time, reuses waste, and provides local jobs.
due to its cylindrical form and cross-strut design, 'thab' becomes durable and sturdy, also featuring an L-shaped combustion chamber
which becomes imperative in reducing heat lost, and lessening the amount of smoke that is produced during cooking.
the design is an effort to improve the traditional thab burner for the tibetan nomads who live and cook inside tents,
created specifically for portability and easy disassembly due to the traveling lifestyle of her user.

Where are these Remote Communities in the U.S.? ..and, Jesus, is everyone a politician; ‘Creates local jobs’. For Chinese laundries or rock breakers at the local jail?
I do like the thinking, the design.
The Rocket Stove is a great way to learn the difference between Thermal Mass and Insulation–which this stove gets wrong.
Rocket Stoves burn cleanly and efficiently because they burn very hot, so more of the material that would become particulate pollution or gases is burned.
One of the design aspects of rocket stoves is the firebox is insulated, usually with ash, vermiculite, rock wool etc.
Rocket Mass Heaters have thermal mass placed around the stove exhaust AFTER the insulated firebox. This way the insulation helps raise the temperature for effective burning, but the hot gases can be used to warm mass, which will radiate heat over time.
So, this stove, while it may be an improvement over the three-rock fire, will not quickly achieve the burn temperatures needed for clean burning.
The design is really cool, description looks unnecessary though.
+1 what ruben said. This isn’t design, this is someone reverse engineering a design without comprehending it.
It looks cool, and I’m very fond of the objective of creating more sustainable methods of cooking and heating in devolping cultures, but I think a proper design for that purpose needs to rely on locally sourced materials, not american coat hangers.
Bottom line: c- for functionality, but A+ for looks and ethics!
