The Hot Ash rocket stove is designed with primary and secondary burns so they burn hot and efficient. Boil a cup of water with just a handful of sticks, wood pellets, or most other biofuels.
“The SilverFire® Mini Mongolian Dragon is a natural draft single burner chimney stove. This stove is heavy, with a refractory ceramic combustion chamber, to provide mass for radiant heat in addition to cooking in a small footprint. Cost: $380”
“British company Anevay’s portable wood-burning Frontier Stove was first conceived and built for humanitarian aid use in disaster zones around the world. But the stove appealed to camping enthusiasts, and the company began retailing the compact, durable, lightweight stove suitable for heating and cooking.
“The challenge of the design of the Cabin Stove was to come up with something that was very compact but also still resembled and functioned like a masonry heater. The design criteria included heating the small space, an efficient and clean fire, utility for cooking, heating water, combining some quick/immediate-release heat with slower retained radiated heat, relative ease of construction, not too expensive, aesthetically pleasing, and being as compact in size as possible. A very interesting process to try to combine all of these together.”
I love rocket stoves and mass heaters and have been recommending them for years. However, there are limitations to everything. Here’s a report from frigid Canada where a rocket mass heater wouldn’t work.
Rammed Earth for Everyone has some very interesting rammed earth cookstoves and wood stoves with lots of photos that show how they’re built. Looks simple enough for any do-it-yourselfer. Cost would be negligible if the forms were reused to build additional stoves.
