The PupStove is a bi-fuel fan-free stove with flame control and offers a carbon-negative cooking experience for car and motorhome campers. Sturdy, stainless steel construction, no assembly required. 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. Using the PupStove 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.
