“The annual cost of a rocket mass heater is less than a tenth of the annual cost of natural gas – and that’s if you buy the fuel instead of harvest it yourself. And a rocket mass heater emits less than a tenth of the greenhouse gasses. Many rocket mass heaters will heat a home with a tenth of the wood of what a conventional wood stove will use.
“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.”
This design will convince people to buy the rocket stove because you heat the water while cooking. Also, this design will enable someone to have hot water for another pot while heating up a single pot.
“Stan Leopard used to spend nearly two hours in the car each day commuting from his home in Mill Valley, CA to his office in San Francisco. Since he runs a small business and can choose where to locate the office, bought a live/work townhouse in a neighboring town and cut his commute to a flight of stairs.”
Fuel Efficient Cooking with an Insulated Box
“What a great example of using a retained heat cooker! Cooking beans is the perfect example of the strength of using a thermal type cooker. All the goodness with 80%-90% of the fuel being saved.”
