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 ...
The lorena is an innovative cooktop design specifically for rocket stoves, aimed at enhancing heat transfer and overall cooking efficiency. It functions by incorporating a metal plate featuring a central hole positioned directly above the rocket stove's burn chamber. This central hole allows for direct heat application to large pots, ensuring rapid heating. Furthermore, the metal plate itself serves as an additional cooking surface, offering versatility for various cooking tasks. The lorena's design seeks to maximize the utilization of heat generated by the rocket stove, making it an energy-efficient cooking solution. Proposed implementations of the lorena often include integration into an outdoor kitchen setting, enhancing its practicality. The sources mention the lorena as an example of the continuous innovation and improvement within the realm of rocket stove technology.
HUSP, an acronym for "Horticulture of the United States of Pocahontas," represents an advanced, nature-centric agricultural system envisioned by Paul Wheaton. It goes beyond contemporary permaculture, envisioning a future where food production systems have undergone centuries of optimization, inspired by traditional Indigenous practices that existed before European colonization. HUSP posits a hypothetical United States of Pocahontas (USP), where agriculture prioritizes harmony with nature, rejecting environmentally harmful practices like plowing and the use of petroleum-based fertilizers and pesticides. This system would not only produce abundant, nutritious food, but also lead to improved human health and a thriving health tourism industry within the USP. Achieving HUSP in the real world necessitates collaborative experimentation and knowledge exchange between permaculture, biodynamic farming, and native plant cultivation practitioners. This would involve a 2,000-acre plot divided into smaller sections, where experts can develop and refine HUSP principles, fostering innovation and leading to a future where food production systems are deeply integrated with natural ecosystems. Crucially, this project requires a supportive environment with minimal government regulation to encourage creativity and accelerate progress toward a truly sustainable agricultural future.
Hugelkultur, is an advanced permaculture technique for creating self-sufficient, raised garden beds by burying wood beneath the soil. Hugelkultur beds can be built in various shapes and sizes, from small backyard gardens to large farm-scale operations. This technique utilizes a variety of wood, from small twigs to whole trees, which decompose over time to create a beneficial environment for plant growth. The wood acts as a sponge, holding water and reducing or eliminating the need for irrigation. As the wood decomposes, it attracts beneficial microorganisms and releases nutrients, creating a fertile "soil on wood" environment that requires minimal fertilization. Hugelkultur is an environmentally sustainable technique that utilizes organic materials that would otherwise be discarded, embodying the permaculture principles of working with nature and reducing waste.. This technique is also applicable to diverse climates and has been proven effective even in desert environments
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.
WOFATI, an innovative sustainable building technique coined by permaculture advocate Paul Wheaton, stands for Woodland Oehler Freaky-cheap Annualized Thermal Inertia. The design utilizes readily available natural materials like wood and earth to create a "soil on wood" structure that harmonizes with the surrounding woodland. The "freaky-cheap" construction methods pioneered by Mike Oehler and further developed by Wheaton significantly reduce building costs. WOFATI structures are characterized by a double layer of membrane, a "two-skin" system that encapsulates the earthen roof, ensuring dryness and longevity. The principle of Annualized Thermal Inertia is key, using the earth's mass to regulate temperature, providing passive heating in winter and cooling in summer. WOFATI houses feature large windows on the uphill side for optimal passive solar gain, while the downhill side typically boasts a large gable roof, also incorporating glazing for natural light penetration. Allerton Abbey, located at Wheaton Labs, serves as a prime example of a WOFATI house
