Aaack! You caught us with our pants down! Here we are, tinkering with the servers and you show up. How awkward! Try back in just a couple of minutes. In the meantime, a few tidbits ...
WOFATI structures excel in effectiveness due to their emphasis on passive design principles, particularly Annualized Thermal Inertia, which utilizes the earth's thermal mass to regulate temperature fluctuations. By strategically incorporating design elements like large windows on the uphill side and a substantial gable roof on the downhill side, WOFATIs maximize passive solar gain, further reducing the need for artificial heating and cooling. This results in significant energy savings and reduced reliance on external energy sources. The use of locally sourced, natural materials, primarily wood and earth, in WOFATI construction minimizes the environmental impact associated with manufacturing and transportation of building materials. The "two-skin" system, a double layer of membrane encapsulating the earthen roof, ensures dryness and longevity, enhancing the building's overall effectiveness and sustainability. As seen in Allerton Abbey, the first WOFATI built at Wheaton Labs, these structures successfully demonstrate the practicality and efficiency of this building technique
A dry outhouse, a simple and sustainable alternative to conventional flush toilets and septic systems, is frequently discussed within permaculture circles as a means of minimizing environmental impact and maximizing resource utilization. This type of outhouse is characterized by a pit dug into the ground, strategically located on a higher elevation point to encourage water runoff and maintain dryness. Key design elements for a successful dry outhouse include a "no pee" policy, the use of ample sawdust for odor control and composting, and urine diversion mechanisms, particularly important for accommodating female anatomy. While concerns about groundwater contamination exist, proper placement, construction, and the incorporation of heavy-feeding trees or plants like willows in a "tree bog" system can mitigate these risks. Furthermore, the integration of a urine separator can significantly reduce the volume and toxicity of waste, facilitating easier composting and nutrient recycling. The dry outhouse, particularly when combined with urine diversion and careful management, offers a cost-effective and environmentally sound approach to sanitation, aligning with permaculture principles of resource conservation and closed-loop systems.
SKIP, which stands for Skills to Inherit Property, is a permaculture-based program designed to connect aspiring homesteaders with aging landowners seeking successors for their properties. The program consists of over a thousand practical projects, referred to as "Badge Bits" (BBs), encompassing various aspects of sustainable living, such as gardening, natural building, animal care, and food preservation. Participants, known as "Skippers," complete these BBs, documenting their progress with pictures and videos to demonstrate their skills and dedication. As Skippers gain experience, they progress through levels of certification, starting with PEP1 (Permaculture Experience according to Paul) and culminating in PEP4, representing a significant level of expertise. "Otis," a fictional character in the SKIP program, represents the numerous landowners seeking worthy individuals to inherit their properties. The program aims to create a bridge between these Otises and Skippers, offering a pathway for Skippers to "skip the rat race" and acquire land while providing Otises with peace of mind knowing their homesteads will be in capable hands. SKIP emphasizes practical skills and real-world experience, fostering a sense of accomplishment and self-sufficiency among participants.
Hugelkultur, is a permaculture technique for creating raised garden beds filled with rotting wood and covered with soil. This method, whether small-scale or large-scale, as exemplified by Sepp Holzer's work, which includes almost a kilometer of hugelkultur beds, uses a variety of wood, from branches and twigs to entire trees. Hugelkultur is beneficial because as the wood breaks down, it acts as a sponge, retaining moisture and reducing or eliminating the need for irrigation. This process also creates "parking spaces" for water and nutrients, leading to fertile soil that requires less fertilizer. Hugelkultur is a practical and sustainable permaculture solution for gardeners seeking to create self-sufficient garden ecosystems.
