here is a list of all the rocket mass heaters and rocket stoves at wheaton labs. there are links to their individual threads as well, some of them have great, super-detailed threads, some of them don't. feel free to start a thread about an individual one if you think it necessary and post a think to it in this thread. and there are some videos too!
The person that created this tried too many new things at once and ended up with something that didn't work. Peter van den Berg modified it to work in the short term as a "rocket heater" but then created the double shoe box rocket cook stove to replace it.
So I bought the dvd sets and Love the info off of them.
As I'm going through these i don't see something that I'm curious if anyone has tried. Most of the piping runs on an incline then to the stack.
And all the pipes run in a mass for sitting on , etc. Has anyone tried to do a vertical mass against a wall?
My thinking is if someone had a basement like a dirt floor basement, running the pipes so they zig zag up the sides of the wall, then packed in with cob, masonary work or what have you creating a radiant heat in the basement that warms the floor above or something to that effect.
kinda....but i was thinking with the duct work starting at the bottom and winding its way up to the top inside kinda like an old wooden marble machine toy, then filling in the wall with stone or something. instead of an giant open center.
Every turn in the chimney is like adding feet to the length. After a few turns the chimney is in danger of not drawing. Thus the stove develops an airlock and the fire goes out (or smokes into the room). I don't know the formula for determining the maximum amount of chimney the stove could support, but in my early years of heating my home with a wood stove I made the mistake of putting too many bends in the stove pipe.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
