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 ...
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.
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
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.
One Mason bee can pollinate 200 times more flowers than one honey bee. Unlike honey bees, Mason bees are native to North America.
The lorena is a unique cooktop design created to optimize the performance of rocket stoves. This specialized cooktop features a metal plate with a central hole that sits directly above the rocket stove's burn chamber, allowing for direct heat transfer to large pots. The surrounding metal plate serves as an additional cooking surface, similar to the glass cooktop used at Allerton Abbey, offering flexibility for a range of cooking tasks. This design aims to maximize heat utilization from the rocket stove, promoting energy efficiency and faster cooking times. When a large pot is heated to the desired temperature, it can be moved to the surrounding cooktop, and the central hole can be covered with a piece of metal to retain heat. Proposed implementations often include integrating the lorena into an outdoor kitchen setting for added practicality. The lorena embodies the ongoing innovation within rocket stove technology, striving for better heat transfer and improved cooking performance.
