Solar house promises greener heating for Tibetans http://apocadocs.com/s.pl?1231865693
Chinese engineers have designed a solar house for Tibetans that aims to reduce their dependency on cattle dung for warmth.
A typical Tibetan family living in a remote mountainous village burns 300 sacks of dung -- around 2,000 kilograms -- each year, half of which it must purchase. But burning dung is inefficient and, in winter, temperatures plunge indoors.... Zeng Yan, chief architect of the Institute of Solar Building Technology, part of CNECHS, said that the experimental house, to be built in May, is supported by three core techniques: insulation, energy collection and energy storage.
The 100 square-metre house has an embedded greenhouse that collects the sun's energy, which can be transferred to the surrounding bedrooms and living room by opening connecting windows and doors.... But Xie Yuan, head of the Department of Science and Technology of Qinghai Province said that the houses might be unaffordable for local Tibetans. The annual personal income in a typical village is less than 1,700 Chinese yuan (around US$249), but the new house costs nearly 40,000 yuan (around US$5,850).

I suspect this is a price point that would allow overnight shipping to the US.
