Rocket Stove to the Sky

Rocket Stoves (rocket mass heaters) are heaters; they heat the house. They’re “super efficient furnaces.”

FURNACES INFORMATION: The efficiency of furnaces is measured in AFUE, which is a number that shows the percentage in efficiency (A greater AFUE results in a greater efficiency). High efficiency furnaces range from 90 to 97%, while low efficiency furnaces range from 80Image% and less.

90-97% is already pretty efficient for a furnace, so how can rocket stoves beat that? I don’t even know. The efficiency of rocket stoves haven’t been professionally analyzed yet, so there’s not really a specific number that shows it; not in the AFUE (if someone can tell me otherwise, please do! I’ve been looking for an answer from many sites now, but I can’t seem to find a proper answer). Guaranteed however, rocket stoves are a very efficient way to heat up one’s house (efficient as in the amount of fuel – wood – put in will bring you a lot of heat, and for a long time too – which is up to 4 days).

In the picture on the right: Wood and oxygen go in on one side to be burned in the burn chamber and then transferred into the steel drum. The steel drum brings out some of the heat directly out into the house for immediate heating, while the rest of the heat is transferred through a long, airtight duct to keep the heat circulating around the house to have constant heating. The duct is usually covered with clay, mud, stone and many other materials and then covered with a ceramic spray to keep everything together. This clump of clay, mud and stone (and many more materials) that covers the duct can be used a furniture; a couch; a bed; a table; anything.

This is the only website I’ve seen so far that sells rocket mass heaters:

Functions for a Cabin (and any other house)

Wouldn’t it be nice to escape from the city; go to somewhere quiet and secluded; to be one with nature. I’m not talking about a camping trip; more like a cabin in the woods.

To be one with nature; you gotta have the look: Those new-looking houses won’t really fit in the whole “nature” theme and it won’t really fit in middle of a bunch of trees either. The overall look of the cabin has to be rustic, with mainly from Victorian-style aesthetics (your choice actually; it’s just that I’d prefer Victorian-style over other rustic designs) with additional adjustments from our new-day technology, such as having side-sliding windows and electricity generating systems like wind turbine generators or pico-hydro generators so that we’ll do as little harm to the environment as possible (net zero energy footprint, net zero carbon footprint…). The cabin (and any other house) would need to have these functions:

volumetric space design – smartly using the space given to us, including space for sleeping, the living room and a bathroom (in this case, a small cabin would be around 500 square feet)

energy system – a way to generate, distribute and store energy for use (for small things like lighting or the composting toilet)

water system – to gather, store and distribute water (this includes having a rain barrel and having a grey-water system. A greywater system is something that reuses the water that’s used for bathing, washing hands or from the toilet for use for watering plants – NOT FOR DRINKING)

waste management system – get rid of all types of waste, like human excreta and compost. Food wrappers and other non-compostable things should be carried out with you back to the city to be disposed of there (includes things like a composting toilet and a composting area)

climate control system – keeps the temperature warm during cold temperatures and cool during hot temperatures
