Solar Greenhouses, Chinese Style

Chinese-style solar greenhouse.“Another alternative is a greenhouse design developed in northern China in the mid-1980s that relies primarily or entirely on solar energy for heat. By 2000 these greenhouses already covered about 260 thousand hectares (650 thousand acres) in northern China, and by 2004 they were supplying residents of northern China with 90% of their fresh produce in winter… That’s when Manitoba vegetable farmer Wenkai Liu first brought the technology to North America. Other Manitoba growers have adopted the design since then, but, to my knowledge, it has yet to be tried in other regions of Canada or the United States.”
