Permaculturist Paul Wheaton just sent me a link to this new video featuring the extremely fuel-efficient build-it-yourself rocket stove / mass heater. It offers, in Paul’s words, “A compilation of 12 rocket heaters, 8 video clips of rocket mass heaters, 2 video clips of pocket rockets, 1 picture from the cover of the book on rocket mass heaters and one drawing from me making a feeble attempt to explain what these look like. And look! A peek at the author Ianto Evans!”

You can watch several other rocket stove videos on YouTube here.
