DIY Heat Recovery Ventilator (HRV) Plans Search The Renewable Energy site for Do-It-Yourselfers DIY HRV Plans This is an article that was published in the 80's and provides good detail on building a Heat Recovery Ventilator from Coroplast sheets. The HRV is not an easy environment for materials in that water and even ice may be present at times. I think that the Coroplast sheets should stand up well to this environment, but the plywood housing may have a limited life.

Step-by-Step Earthbag Building This Instructable explains each main step of construction for building vertical earthbag walls. Videos on my Earthbag Natural Building YouTube channel demonstrate the process. For those who don’t know, earthbag building uses polypropylene rice bags or feed bags filled with soil or insulation that are stacked like masonry and tamped flat. Barbed wire between courses keeps bags from slipping and adds tensile strength. MoSan- Mobile Sanitation Donkey vs. push cart Today we modified the collection service of feces containers. Donkeys need time to get used to a new area. Since we currently don’t have the time, we decided not to go with the donkey again.

Setting Up a New Worm Bin In my last post I discussed dumping out my ‘Coffee Cup Challenge” bin due to excess moisture levels in the bottom of the bin. That same day I started preparing the empty bin for my next round of worm composting As always, I started the process by focusing on bedding. The Jean Pain Way - PermacultureNews.org In the book Another Kind of Garden, the methods of Jean Pain are revealed. He spent his entire short-lived life studying brush land and forest protection, specifically fire prevention, alongside his wife Ida. These studies led to an enormous amount of practical knowledge for composting, heating water, as well as harvesting methane, all of which are by-products of maintaining a forest or brush land with fire prevention techniques. While this knowledge is applicable in many instances, it is worth remembering that the root of all of this knowledge lies in forest preservation. All of the activities described below are by-products of that process. The book goes into detail with the economics of such an operation.
Building technologies: Precast concrete pavement lights Technical author Kevan Brassington introduces these ubiquitous units, described in the NBS work section, H14. Used to allow light to basement areas, pavement lights first appeared in London in the late 1880s in the form of cast iron frames glazed with cut squares of glass. Plain glass fenestration was quickly superseded by pressed glass lenses, which in turn were succeeded by pressed glass prism lenses designed to transmit as much light as possible. Reinforced concrete, patented in France by Joseph Monier in 1867 (for the production of garden ornaments), and the introduction of machine-made glass in 1903, allowed French architect Joachim to build the first glass and concrete dome a year later.
How to Build a Food Dehydrator - DIY When I first took up self-reliant country living in the 1960s, I tried drying foods in a sandwich of old window screens laid at a sun-facing angle across a pair of sawhorses, but found that Mother Nature dries slowly in our changeable New England weather. I also tried an antique sheet-metal wet-heat corn dryer designed for wood-stove-top use, but its single, rusty-hardware cloth tray left barbecue-marks on the apple slices. Plus, it was too small to keep up with our kids' hearty appetite for dried delicacies. In the 1970s I gave in to progress and got one of the MacManniman's big yard-square electric food dryers. For two decades, its gentle electric heat preserved apricot halves and apple sections for babies to teethe on, along with other fruits, fishes and meats.
Adding the center yogurt cup. With the inner and outer buckets assembled, insert the yogurt cup into the center hole and determine how much, if any, needs to be removed from the bottom of the cup.

Wood Burning Electricity Generating Stove INDIGIRKA-2 During the process burning the stove generates the direct current of 12 volts and power not less than 60 watts, which is transferred to the control block and then to the external clamp outlets. The electricity generators enter stable operation mode 12 – 15 minutes after fire starts. Generators supply enough energy to light 2-3 energy-efficient bulbs, charge notebooks, cells, tablets, cameras, watch a portable TV or listen to radio, and so on. It’s not very much – but in emergency situations it will allow you to operate vital and lifesaving devices, and use ordinary wood, pellets, charcoal as fuel. You may want to keep it safe in your backyard, just for a case. The small weight and dimensions allow transportation of the stove and installation in any accessible place.
Eurban solid timber panels are from sustainably managed forests and minimise on-site construction waste at Sustainable Guernsey January 31st, 2011 by Sustainable Guernsey Atelier BasMooArc designed the new home at Portelet using Eurban solid timber panels. Eurban sourced their laminated pine panels for the Portelet home from a manufacturer in Switzerland. The panels were manufactured from slices of glued laminated timber or glulam (as opposed to layers of board) which changes the grain direction and makes the panels more dimensionally stable.
