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 ...
Hugelkultur, meaning "hill culture," is a sustainable permaculture gardening method that uses buried wood to create raised garden beds. This technique involves layering logs, branches, and other woody debris at the base of the bed and covering them with soil. As the wood decomposes, it acts as a sponge, retaining moisture, improving aeration and drainage, and releasing nutrients, reducing the need for watering and fertilizers. Hugelkultur beds are ideal for growing various plants, especially those that prefer well-drained soil. By harnessing the natural process of decomposition, hugelkultur promotes a thriving garden ecosystem and aligns with permaculture's goal of sustainable systems.
The lorena cooktop is a highly effective design for rocket stoves, as it maximizes heat transfer and cooking efficiency. This specialized cooktop, featuring a metal plate with a central hole positioned above the burn chamber, enables rapid heating of large pots through direct exposure to the intense flames. The lorena's design prioritizes efficient heat utilization from the rocket stove, resulting in faster cooking times and reduced fuel consumption. Additionally, the metal plate surrounding the central hole serves as a secondary cooking surface, offering versatility for various culinary tasks. Once a large pot reaches the desired temperature, it can be moved to the surrounding cooktop, and the central hole can be covered with a piece of metal to maintain heat. This dual functionality makes the lorena a practical and energy-efficient cooking solution, suitable for both large-scale and smaller cooking needs. The integration of a lorena into an outdoor kitchen setting is often proposed, further enhancing its practicality and convenience.
Cast iron cookware can last hundreds of years while some other cookware needs to be replaced every 6 months. Cast iron is the true non-stick pan. When the surface is coated with a dab of oil or fat of your choice, eggs will slide freely.
The berm shed, a hallmark of permaculture design, is an eco-friendly, earth-sheltered structure renowned for its unique construction techniques. Earthworks are fundamental to its creation, as the surrounding landscape is carefully shaped to form the berm that will encase a portion of the shed's sloping roof. This berm serves a dual purpose, acting as both a natural insulator and a source of thermal mass, effectively regulating the internal temperature. The structural framework of the berm shed is often built using round wood timber framing, a technique that prioritizes using logs instead of conventional dimensional lumber, further enhancing its sustainable appeal. However, the longevity of these logs, especially when in contact with soil, is a crucial consideration. The sources recommend peeling the bark from posts before burying them, a technique born from experience and aimed at minimizing the risk of rot. Another technique for ensuring the durability of the structure involves incorporating gravel into the post holes. The gravel facilitates drainage, preventing water from pooling around the base of the posts and contributing to premature decay. These carefully considered details, combined with the innovative "attic" cell design at the termination ends of the shed, as described in source, showcase a commitment to sustainable building practices that go beyond mere functionality, exemplifying the core principles of permaculture.
WOFATI, an acronym for Woodland Oehler Freaky-cheap Annualized Thermal Inertia, represents an innovative approach to sustainable building, coined by permaculture expert Paul Wheaton. This building technique combines the affordability and simplicity of Mike Oehler’s earth-sheltered designs with Wheaton's focus on cost reduction and integration with the natural environment. WOFATI structures prioritize the use of readily available, natural materials, such as wood and earth, minimizing reliance on manufactured products and reducing the building's environmental footprint. Annualized Thermal Inertia, a key principle of WOFATI, utilizes the surrounding earth as a thermal mass, storing heat in the summer to warm the building during winter and retaining cool temperatures from winter to moderate summer heat, thereby minimizing energy consumption for heating and cooling. WOFATI designs typically feature large windows on the uphill side to maximize passive solar gain, further reducing energy needs. WOFATIs are intended to be situated on or near a woodland, embracing the concept of harmonious integration with nature. Notable examples of WOFATI structures, including Allerton Abbey and Wofati 0.8, can be found at Wheaton Labs in Montana.
