Piec rakietowy
Piec rakietowy jest piecem podwójnego spalania. Oznacza to że oprócz drewna spala się również gaz drzewny, który w normalnych piecach, kominkach i kotłach opalanych drzewem wylatuje przez komin. Materiały: Przy budowie pieca rakietowego potrzebne są materiały należące do trzech zasadniczych grup:I. Elementy składowe pieca rakietowego (rysunek) Piec rakietowy w wersji grzewczej (mass heater) składa się z dwóch zasadniczych obszarów konstrukcyjnych – spalającego i odprowadzającego spaliny. Konstrukcja spalająca składa się z trzech elementów:1) pionowy podajnik paliwa (symbole A i B na rysunku), -2) pozioma komora spalania (symbol C na rysunku).3) wewnętrzny pionowy komin spalający – ang: heat riser (E i F na rysunku). Elementy 1) i 2) najlepiej zbudować z cegieł szamotowych ale dopuszczalny jest każdy materiał odporny na działanie wysokiej temperatury (kamień, gruba stal, itp.)

DIY Naturally Scented All-Purpose Citrus Vinegar Cleaners
I've been on a quest to rid our home of toxic chemicals for both health and environmental reasons. Did you know? According to the Environmental Protection Agency, indoor air can be 10 times to 100 times more polluted than outdoor air. UGH! After my recent post about using fruit, herbs, and spices for making natural home fragrances, it occurred to me that I could use some of those same scent combinations for making natural cleaners with vinegar. These scented cleaners don't completely eliminate the vinegar scent when first sprayed. THESE MAKE COOL, INEXPENSIVE GIFTS. HOW TO MAKE NATURAL CLEANERSwith vinegar, citrus, herbs, and spices Assemble these ingredients: view on Amazon: essential oils, bulk pricing on cinnamon sticks, whole cloves Assemble these supplies: Jars or other sealable containers. view on Amazon:half gallon mason jars, quart mason jars, spray bottles,jar funnel, mason jar lid strainer, wire mesh strainer view on Amazon: citrus scorer/peeler OOPS ALERT!

Casting in hypertufa is fun and not at all difficult. Hypertufa is a mixture of Portland cement, sand and peat moss. If you want you can replace the sand with perlite, it makes the pots and trays a lot lighter as perlite weighs almost nothing. Tufan takes a little longer to harden than ordinary concrete. When casting bigger things it is a good idea to reinforce the castings. A concrete mixer is very useful and makes the casting so much easier. When casting larger pots and trays, I use buckets of different sizes ordinary cardboard boxes and plastic tubs as molds.

How to Sharpen Tools: The Family Handyman
Sharpening your tools Years ago, I drove by a storefront with a hand-painted plywood sign. It read “Tool Sharpening.” Curious, I gathered a boxful of dull old handsaws and circular saw blades in my garage and carried them up to the store with the hope of getting them sharpened. Inside I saw a lean old fellow with wisps of gray hair curling from the backside of an old hunting cap. A week later when I walked into the store, he asked me what my name was and started rummaging through a pile of bags and boxes. The next day I gathered my garden tools and brought them down to the same shop. A moment passed, then he looked me in the eye and said, “Why don’t you do it yourself?” That afternoon changed forever how I look at tools. Do It All with Three Simple Tools A Grinding Wheel, a Mill File and a Sharpening Stone You can sharpen most garden tools with a simple 10-in. mill bastard file (Photo 5). A grinding wheel (shown in Photo 4) is good only for removing larger amounts of steel. 1 of 7 2 of 7
Recent Research on Rocket Mass Heaters (and Bell Design) | Hand Print Press
There appears to be a huge amount of traffic and discussion through different internet forums about rocket mass heaters and reports from the authors on sales of the book on the subject confirm this incredible surge in interest. I am quite certain that this excitement stems from the tangible possibility that the rocket mass heater concept offers to individuals and families to build their own affordable efficient wood-fired heating system. I thought it would be interesting and useful to offer the following synthesis of recent research I have been directly involved in and links to information that others have provided to feed more fuel to the fire of this interesting global conversation. Article Table of Contents: The Difference between Rocket Stoves and Rocket Mass Heaters First, a clarification regarding terms may be useful. The Book on Rocket Mass Heaters There is a wonderful book on Rocket Mass Heaters. The MHA Experience Construction Processes with Commentary Conclusion: Suggest a link!
Why Trees Matter
TREES are on the front lines of our changing climate. And when the oldest trees in the world suddenly start dying, it’s time to pay attention. North America’s ancient alpine bristlecone forests are falling victim to a voracious beetle and an Asian fungus. In Texas, a prolonged drought killed more than five million urban shade trees last year and an additional half-billion trees in parks and forests. In the Amazon, two severe droughts have killed billions more. The common factor has been hotter, drier weather. We have underestimated the importance of trees. For all of that, the unbroken forest that once covered much of the continent is now shot through with holes. Humans have cut down the biggest and best trees and left the runts behind. What we do know, however, suggests that what trees do is essential though often not obvious. In Japan, researchers have long studied what they call “forest bathing.” Trees also release vast clouds of beneficial chemicals.
