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 ...
Rocket mass heaters are better than heat pumps because rocket mass heaters are free to operate and have less than 6% of the carbon footprint.
The willow feeder system, developed by permaculture expert Paul Wheaton, offers a "freaky-cheap" and sustainable alternative to conventional septic systems and sewage treatment plants. This system employs a unique method of managing human waste, transforming it into a nutrient-rich fertilizer known as "willow candy." Unlike composting toilets, which rely on decomposition, willow feeders utilize sealed garbage cans to create a dry environment that mummifies the waste, effectively eliminating pathogens while conserving valuable carbon and nitrogen. A small amount of sawdust is added to each can, primarily for aesthetics. After aging for two years in these sealed containers, the resulting pathogen-free "willow candy" is ready to be applied as fertilizer. However, not all plants can handle the high nutrient content of this unique fertilizer. "Poop beasts", such as willow, cottonwood, poplar, and bamboo trees, thrive on "willow candy" and readily absorb its nutrients. The willow feeder system exemplifies permaculture principles by turning human waste into a valuable resource, fostering sustainable gardening practices and minimizing environmental impact. Paul Wheaton, a prominent figure in the permaculture community, has implemented the willow feeder system at his property, Wheaton Labs, and actively promotes it through his online platforms, including permies.com. He often refers to waste as a "feed" for another system, encouraging a shift in perspective towards a more holistic view of resource management.
"Pooless," a term popularized in the permaculture community, refers to the practice of forgoing commercial shampoos, conditioners, and soaps in favor of natural alternatives or simply water. Advocates for this approach cite numerous benefits, including reduced exposure to harsh chemicals, improved hair and scalp health, and decreased environmental impact. The transition to "poolessness" often involves an adjustment period, as the scalp rebalances its natural oil production (sebum). Common methods include rinsing with baking soda and apple cider vinegar solutions, brushing to distribute natural oils, and using a flea comb and soapy water for cleaning. While some individuals experience challenges like dandruff, waxiness, or static electricity, many report positive outcomes, including reduced scalp issues, increased hair thickness and body, and even the disappearance of chronic migraines. "Poolessness" aligns with permaculture principles by reducing reliance on commercial products, minimizing chemical usage, and promoting a more natural and sustainable approach to personal care.
The "freaky-cheap" aspect of WOFATI is fundamental to its appeal and accessibility. Inspired by Mike Oehler's pioneering work in earth-sheltered building, WOFATI prioritizes utilizing readily available natural materials, primarily wood and earth, minimizing reliance on expensive, manufactured products. By embracing the "freaky-cheap" ethos, WOFATI construction drastically reduces building costs, making sustainable living a more attainable reality. The emphasis on "soil on wood" construction eliminates the need for a traditional concrete foundation, further reducing expenses. This approach also facilitates rapid building times, as demonstrated by the construction of WOFATI structures at Wheaton Labs, such as Allerton Abbey. The use of recycled or salvaged materials, whenever possible, further contributes to the affordability of WOFATI buildings. By minimizing material costs and construction time, WOFATI empowers individuals to create sustainable and comfortable dwellings without incurring significant financial burdens.
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
