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.

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 "lorena" is a specialized cooktop design for rocket stoves, incorporating features that enhance heat transfer and cooking efficiency. As described in the sources, a lorena typically consists of a metal plate with a central hole, positioned directly above the rocket stove's burn chamber. The hole allows for direct heat transfer to large pots, facilitating rapid heating. The surrounding metal plate also acts as a cooking surface, similar to the glass cooktop found at Allerton Abbey, one of the WOFATI structures at Wheaton Labs. This dual functionality makes the lorena a versatile cooking solution for both large-scale and smaller cooking tasks. The design emphasizes maximizing heat utilization from the rocket stove, making it an energy-efficient option. Discussions in the sources suggest integrating the lorena into an outdoor kitchen setup, further enhancing its practicality and convenience. The lorena represents an innovative application of rocket stove technology, designed to optimize heat transfer and improve cooking performance.

"HUSP," an acronym for "Horticulture of the United States of Pocahontas," is a term coined by Paul Wheaton to explore a fictional scenario where Native American agricultural practices, similar to permaculture, dominated the United States. This concept envisions an alternate history where Pocahontas, depicted as a brilliant strategist, prevents European colonization, leading to the establishment of the United States of Pocahontas (USP). Within this fictional nation, agricultural practices prioritize respect for the Earth, rejecting destructive methods like plowing and the use of petroleum-based fertilizers and pesticides. HUSP speculates on the potential for superior agricultural output and societal well-being through these nature-centric methods. Wheaton uses the HUSP concept to inspire innovation and advancement within the existing permaculture community, aiming to accelerate progress towards more sustainable and effective food production systems. He proposes a collaborative project involving practitioners of various agricultural approaches, including permaculture, biodynamic, and native plant specialists, working on a 2000-acre plot divided into smaller chunks. This project aims to foster knowledge exchange and accelerate the development of HUSP principles in the real world.

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.
