Donkey’s dual rocket stove

I’m thinking about my next rocket stove, planning, drawing, scrounging and researching rocket stove mass heaters. While surfing the interweb I visited rocketstoves.com to see if there was anything new. I found a link to the rocket stove forum at Rocket Stoves… Experimenters corner. Thanks to Donkey for setting this up. I look forward to reading through the posts.
