The idea of converting organic household waste into energy for cooking is certainly an appealing one, but getting a biogas system up and running in your own backyard can be quite an undertaking. Israeli company HomeBiogas is out to make this a more realistic proposition for eco-conscious households, and has just introduced a third-generation model it says produces 30 percent more clean fuel than its previous system, along with fertilizer to give your plant life a boost.

HomeBiogas first emerged in 2015 by way of a crowdfunding campaign, offering families a way of producing cooking gas by feeding food scraps into a digester chamber. Here, live colonies of bacteria naturally break down the organic matter and produce gas that can be piped back to the kitchen for stovetop cooking, along with liquid fertilizer for the garden. 

The team has since reworked its design based on customer feedback to result in a simplified machine, which is not only easier to assemble but makes is also far more efficient. The company credits a reimagined digester shape, which allows for a larger bacteria biodome, for the 30-percent boost in biogas production, enough for two hours of cooking each day (...) Read more
