I remember as a kid, in India, solar, gobar/bio gas and alternative ways of cooking and heating were all the rage. Then liquified petroleum gas became cheaper and everything just died. Here’s[1] an example of what I’m talking about. It was mostly for rural areas without reliable ways of delivering cooking fuels.

- yegle 4y agoOh wow I vividly remember in the second grade there's a story of grandma cooking noodles using a solar cooker (it was in the Chinese textbook for Mainland China circa 1998). Searching for a couple keywords on Taobao and apparently you can still buy those things. E.g. https://www.taobao.com/list/item/wap/595475929092.htm https://www.taobao.com/list/item/wap/595475929092.htm
- jxramos 4y agoah it's gobar gas, I kept searching for bogar gas in futility just like 2 days ago from an idea an Indian colleague of mine shared with me some 10 years ago. Seems like bio-gas has become the preferred term for this technique.
