One word.......WOW! Fantastic to have come across your forum! Much kudos for coming up with the idea guys. Thanks so much for sharing your innovations. Name's Henk and I've been avidly reading about and watching vid's on rocket stoves and RMH's for probably about 5 years now. Haven't really had to get into serious builds as yet, since our winters down here don't get nearly as cold as our northern friends. I do however find the topics insanely interesting and can not go to youtube or instructables or the like without first looking up the new rockety ideas that have come about. Looking forward to reading about your endeavors and hopefully share ideas as well.
