In 2016, honeycomb coal, along with projects such as the Beidou navigation satellites and the Nanjing Yangtze River Bridge, received a nomination for the Classic Design award at the Beijing International Design Week. We have been using coal for a long time, but lighting it and burning it completely has always been a major problem. To light a coal ball, about 1 jin of firewood is needed; just for this purpose, Beijing consumes over 200 million jin of firewood per year. So, coal dealer Guo Wende came up with an idea: to create \"ventilated coal balls\" by giving the coal a fixed shape and making several holes in it. When these coal balls were stacked together with their holes facing each other, they burned more efficiently. Thus, in 1949, honeycomb coal was invented. Later, some coal production sites introduced technological innovations; workers began using machines to produce honeycomb coal, doubling the output, and honeycomb coal started to reach more and more households. As a child, I never paid attention to briquettes; they were something commonplace, and I had no idea there was such a history behind them.
The days of lining up to buy coal cakes are gone forever: lol
Conditions are improving, standards of living are rising, and there is more availability of goods
Well, first we ruled out buying coal balls, then switched to coal cakes, after that used a small tricycle to deliver liquefied gas, and now it’s delivered directly to the home via pipelines……
There is information online saying that this thing might have been invented in the East around the 1940s
