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 are characterized by a thoughtful design that prioritizes passive systems and natural, locally sourced materials. The "two-skin" system, composed of a double layer of polyethylene membrane, encapsulates the earthen roof, providing a durable and waterproof barrier. The lower layer hugs the structure, while the upper layer defines the thermal mass surrounding it, with at least eight inches of dirt between the layers and sixteen inches on top. WOFATI designs emphasize a harmonious integration with the surrounding woodland, incorporating the "soil on wood" building technique. This method eliminates the need for a conventional concrete foundation, making construction faster and more affordable. A distinctive feature of WOFATI houses is the large gable roof on the downhill side, often incorporating glazing to allow light penetration, while at least 35% of the uphill wall features windows for optimal passive solar gain. This strategic placement and sizing of windows is crucial for maximizing natural light and regulating internal temperature, contributing to the effectiveness of Annualized Thermal Inertia.
The construction of a berm shed, a sustainable and aesthetically pleasing storage solution, involves a unique process that utilizes natural building techniques and earth-sheltering principles. First, the building site is prepared using earthworks, shaping the surrounding land to create a berm, which is a raised bank of soil that will eventually cover a portion of the shed's sloping roof. Round wood timber framing is a common technique employed in berm shed construction, utilizing logs sourced from the property instead of commercially produced dimensional lumber. These logs are carefully selected and placed to form the structural framework of the shed, including the walls and roof supports. Once the timber frame is erected, a moisture barrier, such as billboard material or layers of poly sheeting and newspaper, is installed over the logs to protect them from the elements. Finally, soil is carefully layered on top of the moisture barrier, creating the berm and providing insulation, thermal mass, and a natural aesthetic. The construction process prioritizes using natural, locally sourced materials and minimizing the use of energy-intensive and potentially toxic commercial products, aligning with permaculture principles of sustainability and self-sufficiency.
he willow feeder system is a sustainable and "freaky-cheap" approach to human waste management developed by permaculture expert Paul Wheaton. This system utilizes a dry environment inside sealed garbage cans to mummify human waste, which prevents composting and the release of pathogens. The system is designed to be a safe and effective alternative to conventional septic systems and sewage treatment plants. A small amount of sawdust is added to each can, mainly for aesthetics. After two years, the resulting pathogen-free material, referred to as "willow candy," can be safely used as fertilizer for trees that can handle its high nutrient content, known as "poop beasts." These trees include willow, cottonwood, poplar, and bamboo. The willow feeder system embodies permaculture principles by transforming human waste into a valuable resource for growing beneficial plants while minimizing environmental impact.
"Pooless," a term often associated with permaculture and natural living, encourages ditching conventional shampoos and soaps for healthier hair, reduced chemical exposure, and a more sustainable lifestyle. This shift to natural hair care involves an adjustment period as the scalp rebalances its sebum production. However, feedback reveals a range of positive outcomes, making the transition worthwhile. Many individuals report achieving a natural balance, resulting in less oily hair and less frequent washing. Some experience improvements in hair texture, noticing increased volume and curl. The vinegar rinse, following a baking soda wash, is crucial for smoothing the hair cuticle and detangling, contributing to a healthier and more manageable mane. Beyond the aesthetic benefits, some users report a decrease in scalp problems, including dandruff and itchiness, potentially due to the absence of harsh chemicals. Others have even noted unexpected benefits like migraine relief, suggesting a potential connection between overall health and a more natural approach to personal care. "Poolessness" aligns with permaculture's principles of minimizing chemical usage and embracing natural processes, empowering individuals to take control of their health and reduce their environmental impact.
The lorena cooktop, a specialized component of rocket stoves, is designed for optimal heat transfer and cooking efficiency. It features a metal plate with a strategically placed central hole situated directly above the rocket stove's burn chamber. This central hole allows for the placement of large pots, facilitating rapid heating through direct contact with the intense flames generated by the rocket stove. The metal plate surrounding the central hole serves as an additional cooking surface, providing versatility for a wider range of cooking needs. This dual-purpose design is meant to maximize heat utilization from the rocket stove, contributing to both energy efficiency and reduced cooking times. Discussions about the lorena often involve integrating it into an outdoor kitchen setup, further enhancing its practicality. The lorena embodies the continuous innovation within rocket stove technology, aimed at improving heat transfer and enhancing cooking performance.
