Manufacturer's Description

The Beaner is a bi-fuel fan-free stove without temperature control. Created for backpackers as a carbon-negative camping stove, it’s also currently being used in developing countries as a small cookstove. It can be used with dry biomass (pine needles, wood, etc.) or with any alcohol (ethanol, alcohol, vodka, etc.). It is also possible to add waste plant oil, such as sunflower seed oil, jatrovha oil or olive oil, to dry biomass for a 21% increase in energy. Campers need only add a 8oz soda can as a consumable item. Using the Beaner creates biochar, which enriches the soil and sequesters carbon. This means that you can bury your biochar in the soil where you cook and leave it richer than you found it.

This is a low-cost introduction to micro-gasification which allows you to begin experimenting with turning biomass into clean, blue-burning gas.
