rocketstoves - www.ErnieAndErica.info Ianto Evans, Leslie Jackson, Ernie Wisner, Kirk Mobert, Paul Wheaton, and other friends are among the researchers developing efficient, clean-burning, affordable stoves for a variety of heating and cooking needs. This group developed and published the current editions of Rocket Mass Heater, or Rocket Masonry Stove, designs. The technology combines an innovative clean-burning combustion chamber, with an earthen masonry thermal mass, resulting in extraordinary heat capture and low waste from an incredibly small amount of wood. The goals of Rocket Stove researchers include - meet human needs for food, warmth, comfort, and safety - conserve fuel (over-harvesting of firewood affects droughts, famine, and climate), - clean air, reduce smoke-related health and environmental problems - turn wastes into resources, e.g. find new uses for junk & scrap - encourage resourceful thinking and hands-on problem solving - offer affordable, clean alternatives to conventional technologies
Particulate Emission in Rocket Mass Heaters... Looking for Data!!! (rocket mass heater forum at permies) I was looking for scientific publications on anything closely relating a rocket mass heater just the other day. The closest thing I could find were journal publications on particulate emissions for masonry heaters. The studies were typically performed in Europe. How I found the articles (abstract only typically): scholar.google.com did a search on 'masonry heaters' To my knowledge, I don't think anyone has done any particulate/aerosol studies on RMH. A quick solution maybe an electrostatic precipitator. Yet, in the greater picture forest fires are way more polluting/particulate generating than residential fireplaces.
How to Build a Simple Rocket Cook Stove « Canadian Dirtbags December 13, 2010 by cdndirtbags Rocket (cook) stoves are as cheap and easy or as expensive and full on as you want them to be. Our first one was made using materials on hand: a coffee can, two progressively smaller cans, and a couple of handfuls of diatomite. It was never intended to be anything more than an experiment, as evidenced by the fact that I left it outside to rust for the last year, though it did come in handy when we lost power and wanted hot tea. The basic idea behind the rocket stove is to use minimal (wood) fuel to heat a concentrated area. The stoves are generally meant for outdoor use as they don’t include a chimney. For those of you who just want to get started though, and intend to use the stove outdoors, here is a list of what you’ll need: a large can, and two progressively smaller cans, some scrap metal, clay (optional), and some nonflammable material for insulation like industrial vermiculite, perlite, or diatomite. Then make a hole in your mid-sized can. Like this:

Wood Burning Stoves 2.0 - the DVD(s) by paul wheaton The stretch goals ... If we hit $100,000: I pointed the video camera at all the cool stuff at the workshop, just like I said i would. The crown jewel here is the rocket mass heater, based on rocket stove technology. Ernie and Erica Wisner have built over 700 rocket mass heaters and what was shown at this workshop is the result of their most advanced work to date. Here are Ernie and Erica showing off an earlier rocket mass heater: The first DVD will be "Fire Science". fire burning sideways and upside down bare hands bonfire tricks rumford effect fireplace designs flammable chimney demonstrations stump stove diagrams and physics and math, oh my! The second DVD is called "Sneaky Heat". The third DVD is called "Boom Squish" - named after a series of podcasts where we discuss the dangers and strategies of alternative hot water. The final DVD is called "Hot Rocket". The four DVD set will be called "Wood Burning Stoves 2.0". Thanks for PR help from Hartke Communications. Thanks for the bump from:

Construction d'un chauffage à bois Rocket de masse. Du bois. (Vidéo) Image credit: Paul Wheaton From rocket stoves aiding relief in Haiti, to building your own cookstove, ultra-efficient rocket stove designs have been around for some time. But this one is a little different. Should we be nervous? Admittedly, Paul—who brought us videos on how to build Hugelkultur raised beds, and how to use moldy hay as lawn fertilizer—is not crazy enough to build the whole stove out of wood. Still, it's an interesting and attractive spin on the traditional rocket mass heater.

Dream Dictionary | SmartGirl The significance of dreams has probably been debated since people first developed the ability to communicate. Despite this, there's still no agreement on why we dream. It's hard to believe that dreams have no meaning at all, though, especially when it's so much fun to try to figure out what they're trying to tell us. To help you interpret your dreams, we've developed a dictionary you can use to look up some of the images and feelings commonly found in these night time visions. Choose a letter: Accident Dreaming of an accident is a warning to pay attention to a certain situation in your real life before it gets out of control. Achievement To dream of an achievement denotes that you will be greatly satisfied with the outcome of a situation or project. Acne Dreaming of having acne symbolizes self-esteem issues and your insecurities. Actor/Actress To see an actor or actress in your dream represents your pursuit of pleasure.

Bekijk onderwerp - Rocket stove ontwikkeling Met dank aan Gandalf voor het terugvinden van de tekst na de servercrash van 24 juni 2011. Berichttitel: Rocket stove ontwikkelingGeplaatst: di jun 14 13:42:49 Na de cycloon avonturen had ik me voorgenomen om een oud idee uit te werken. Het zal wel weer te maken hebben met gelaagdheid, in de heatriser dit maal. Verder heb ik het testbed naar binnen verhuisd en aan de bestaande schoorsteen aangesloten. Om kort te gaan, de constructie is eenvoudig. De metingen waren aanvankelijk geen verrassing: de verwachting was dat het ding een heel onrustige grafiek op zou leveren en dat deed het ook. De bovenste rij cijfers achtereen volgens: zuurstof, rendement, koolmonoxide en eind temperatuur. Ik ben gaan knoeien met hoeveel hout er tegelijk in gepropt kon worden zonder hem de hik te laten krijgen. Het is heel eenvoudig om de 2e stroom praktisch te laten stoppen door het hout tegen de kant van de burn tunnel te laten leunen. Voorlopig heb ik nog wel wat te doen! peterberg schreef: Dutch John schreef:
Particules en suspension Visualisation des catégories de particules en suspension dans l'air ou aéroportées (contaminants biologiques, ou particulaires minéraux ou organiques, ou gazeux)... par nature et taille (en micromètres ; μm) Les particules en suspension sont toutes les particules (solides ou en aérosols) portées par l'eau ou par l'air, quantifiables par filtration ou par d'autres procédés physiques. Elles sont - dans leur ensemble - désormais classées cancérigènes pour l'homme (groupe 1) par le Centre international de recherche sur le cancer (CIRC)[1]. Les PM (pour matières particulaires d'après l'expression Particulate Matter(en)) désignent les particules en suspension dans l'atmosphère terrestre[2]. Un taux élevé de particules fines et ultrafines dans l'air est facteur de risque sanitaires (maladies cardio-vasculaires, altération des fonctions pulmonaires, cancer du poumon).

Le Rocket Stove WINIARSKI (four-fusée) Le Rocket Stove WINIARSKI (four-fusée) Durant ces 13 dernières années, des variantes du Rocket Stove ont été construites dans plus de 20 pays. Efficacité : 12-42%. L’efficacité dépend du type d’échangeur de chaleur utilisé. Le coude du fourneau peut être fait à partir de différents matériaux afin d’améliorer sa longévité. Chacune de nos cuisinières à bois comprend une unique chambre de combustion. Ce coude est alors placé à l'intérieur d'un conteneur complètement isolé. Le fourneau-fusée (Rocket stove) est un perfectionnement du feu de camp avec trois pierres, mais constitue seulement une partie de l'équation. Ce dessin montre une mince pièce de métal ( une jupe) enveloppant la marmite.

Styles of Thinking "How do people think about things?" 1. 2. 3. 4. 5. Synthesists "Synthesists are apt to appear challenging, skeptical, or satirically amused, even when you can see no cause for any of that." A Synthesist can juggle both arguments and counter arguments mentally and recognize the validity of each and form new ideas from that conflict. The first common strategy of the Synthesist is that of "Open Argument and Confrontation." Their second common strategy is "Asking Dumb-Smart Questions." Synthesists like to be observers of conflict. The ability to look at opposing viewpoints and not pass judgement is indicative of a Synthesist. Synthesists like to speculate. Even when Synthesists make recommendations, such thinkers challenge their own ideas. Idealists Summary
Bekijk onderwerp - Rocket-stove of een batch-rocket? Zie zo, gisteravond net voor ik naar het werk ging nog vlug de batch rocket zelf uitgetekend met de maten, die ik had van de tabel.Eigenlijk is dit goed in 3 delen te gieten.De boven zijde van de vuur kamer.De riser zelf.En de grond plaat met de zij wanden met schuine zijde in de vuurhaard.Deze laatste zou die in een stuk mogen of zou het beter zijn om de grond plaat en de zij panelen apart te gieten, dit om barsten tegen te gaan. Hier de foto van de batch 177 versie. De riser word 108cm hoog. Met een diameter van 15 a 16 cm naargelang de diameter van de buis. Ik vind om de mal te maken eventueel nog de vuurhaard iets verschalen indien nodig moest de buis 16 cm zijn (binnen diameter). Met deze maat kan de binnen-diameter van de kachel ook al een heel stuk verkleinen om zo op die manier zo dicht mogelijk bij de m² oppervlak te raken zoals de rocket/bell. mvg pedro
Le poêle à bois : danger ou alternative ? Alliant véritable confort de chauffe selon l’isolation de la maison et besoins de chauffage, le poêle à bois est particulièrement simple à installer, puisqu’il suffit qu’il soit raccordé à un conduit d’évacuation. Offrant des performances de chauffe exceptionnelles qui permettent d’élever la température d’une pièce en très peu de temps, jouissant d’une installation facile et modifiable, le poêle à bois reste-t-il un bon moyen de passer l’hiver au chaud ? Le rendement d’un poêle à bois est de 60 % à 80 %, en moyenne par rapport aux cheminées à foyer ouvert, dont le rendement ne dépasse pas 20 %. Il permet en effet, une combustion rapide et diffusion rapide de la chaleur. Toutefois, depuis quelques temps, la question des émissions de particules générées par les poêles et leur impact sur l’environnement et la santé est vivement débattue. Un poêle à bois non certifié émet autant de particules fines en neuf heures d’utilisation qu’une voiture au Canada qui parcourt 18.000 km dans une année
