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. Now it is time for you all to pony up for the DVD's. Once funded, the raw footage will be massaged into stuff that will fit into DVD-like thing-a-ma-jigs. 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.
countryside - homesteading - self-reliance - simple life Most homesteaders get their water from private, drilled wells. Most private wells use electric pumps. Ordinary buckets wont fit in a (commonly) 6″ well casing. Therefore, without electricity, most homesteaders wont have water. ... Stone Construction, with and without mortar: build stone walls, houses, barns fireplaces, entryways, bridges, seats, steps, walls, waterfalls, or a stone barbecue. Stone HouseA Guide to Self-Building with Slipforms by Tomm Stanley Born and raised in the USA, author Tomm Stanley hopped around the world working in Antarctica, Australia, southeast Asia and New Zealand, where he found a partner and settled down. Tomm and Sabrina had lots of rocks available on their land, and so slipforming was the obvious choice for building their dream home. The slipforming method they used is largely to early slipforming methods used in North America, with one significant improvement: Instead of wire ties to hold the forms together, Stanley ran threaded rod through plastic sleeves, and used wingnuts on the outside of the forms to tighten the forms. This book is most appropriate for builders in mild climates since Stanley used only the thermal mass of the walls to moderate hot and cold temperature extremes, much like adobe houses in the southwest. The author uses both Imperial and metric measurements in the book, which makes it useful to readers anywhere.
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. Ook weer in een oude Nederlandse vuilnisbak met een 60 liter olievat er op bij wijze van bell om de geproduceerde hitte op de vangen. Bronnen in de U.S.A. zeggen dat het lastig is om een kleine rocket goed te laten werken. Op de een of andere manier werkt een 150 mm systeem niet altijd goed, het wordt pas leuk als het groter wordt. 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. Voorlopig heb ik nog wel wat te doen! peterberg schreef: Dutch John schreef:

Hempcrete Can Change The Way We Build Everything CNN report on eco friendly sustainable hemp house built in Asheville, NC. Benefits include carbon negative construction, breathability, and reduced cost of heating and cooling. Imagine you had a building material that was energy-efficient, non-toxic and resistant to mold, insects and fire. The material may even have a higher R-value, or thermal resistance, than concrete, a claim that is still being investigated. The only problem? The base of the Hempcrete creation is hemp, which comes from the cannabis sativa plant -- the same one that produces marijuana, which is a federally banned substance. Still, the Hempcrete mixture of hemp, lime and water is being used to some extent for construction jobs across America. Throughout Europe, the use of hemp for construction purposes has spread across many countries. Seeing Hempcrete as a more efficient and sustainable building material has led to some dubbing it as a gateway product. Source: Huffington Post Related:
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. 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

What about Cob Building Codes and Cob Permit Requirements When people first learn about building homes and structures out of cob they get really excited and their imaginations go wild with creative ideas and all the possibilities that the material offers for creating things. Then at some point in our excitement we get a rude awakening to the thought of how we might actually go about building a cob building in our bureaucratic, twisted society. We tend to worry about how we’ll make it past all the laws, regulations, and building codes required to build according to our own imaginations. Not to mention the expensive inspections! In the United States, we follow the International Building Code. The fact is that our current scale system is flawed, behind the microscopic codes money has become the ultimate measure for everything. According to the International Code Council (ICC), the purpose of the International Building Code is to “safeguard public health, safety and general welfare… from hazards attributed to the built environment.”
Houtvergassing Beelden van moderne Finse installaties uit RVS, professioneel gebouwd door amateurs, waren het laatste duwtje in de rug. Deze units zijn efficiënter en gebruiksvriendelijker dan de installaties uit de tweede wereldoorlog en kunnen bovendien gehakseld en relatief nat hout aan. Ondanks het feit dat de meest houtgassers eenlingen zijn, is het niet mogelijk om alles zelf te fabriceren. Mobiele houtvergassing zal de wereld echter niet redden van de ondergang. Het was, is en blijft een methode voor crisistijden en voor idealisten. Wat is houtvergassing? Houtvergassing is een chemisch proces, waarbij met behulp van hitte de vaste bestanddelen omgezet worden in brandbaar gas. We onderscheiden vier processen tijdens de vergassing: 1. Oxidatie, produceert energie: Reductie, ontneemt energie: Grofweg bestaat houtgas uit: 20% koolmonoxide CO 18% waterstofgas H2 4% methaan CH4 8% kooldioxide CO2 50% stikstof N2 De kooldioxide en de stikstof dragen niet bij aan de latere verbranding van het gas.
