In poorer countries, where blackouts are common and supply lines are tenuous, people have to be inventive if they want to heat and light their homes. One way they do this is by building their own biogas generators. You would think this would be very complicated, but it’s a lot simpler than you might think.
Biogas is great because it’s made from things you wouldn’t use anyway–food waste, chicken poop, cow manure, etc. The generator turns this stuff into biogas (mostly methane and carbon dioxide) which you can use as fuel for cooking, lighting, heating, and so forth.
In this article on The Prepping Guide, you’ll learn how to make a simple biogas generator. You only need about ten things including PVC piping and hosing, a T-valve, a funnel, a gas tap valve, a gas holder, and a container such as a water cooler bottle. Follow the link below to check it out.
