Liz To has designed a coat-hanger-based disassemblable stove for Tibetan nomads who cook indoors. It's a clever way of recycling one of the more pernicious waste products of western society (coat hangers) and relieving one of the worst health problems faced by Tibetan nomads (indoor pollution from dung fires). Apart from the rather unfortunate orthography (it's called "thab." — all lower case, with a superfluous period), this is just great.
thab. is designed for Tibetan Nomads who live and cook inside tents. For cooking, they usually use the three stone cooking method however that causes health issues. They use yak dung as their cooking fuels.
They often boil water or soup therefore thab. must be strong, durable, efficient, safe and inexpensive.
Tibetan Nomads travel from one place to another every few months therefore thab. is designed to be disassembled so it can be portable.
