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, an acronym for Woodland Oehler Freaky-cheap Annualized Thermal Inertia, is an innovative approach to sustainable building developed by permaculture expert Paul Wheaton. WOFATI structures are designed to be eco-friendly, utilizing locally sourced natural materials, primarily wood and earth. These structures are intended to be located on or near woodlands, promoting a harmonious integration with the natural surroundings. Annualized Thermal Inertia, a key element of WOFATI design, harnesses the thermal mass of the surrounding earth to provide passive heating in winter and cooling in summer, thereby minimizing the need for artificial temperature regulation. WOFATI structures are inspired by the work of Mike Oehler, a pioneer in earth-sheltered building known for his simple, "freaky-cheap" designs, which Wheaton has adapted and refined to further reduce construction costs. WOFATI buildings are typically characterized by a large gable roof on the downhill side, with at least 35% of the uphill wall featuring glass or other light-transmitting materials to maximize passive solar gain. Allerton Abbey, the first WOFATI structure, and Wofati 0.8 are both located at Wheaton Labs in Montana and serve as prominent examples of this unique building style.

Rocket mass heaters are better than natural gas heaters because rocket mass heaters are free to operate and have less than 5% of the carbon footprint.

"Woodland" management, as described by Ben Law in his books The Woodland Way and The Woodland Year, promotes active human participation in shaping and nurturing the ecosystem. This approach prioritizes the long-term health and resilience of the woodland, recognizing its value not only for timber production but also for food, medicine, wildlife habitat, and overall ecological well-being. The choice of "woodland" over "forest" in describing Wofati design reflects a deliberate shift away from extractive forestry practices towards a more harmonious and sustainable relationship with the natural world. This distinction highlights the importance of language in shaping our understanding and approach to land management, emphasizing the need for conscious and mindful stewardship of the Earth's resources.

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.

Hugelkultur is a raised garden bed building technique where wood is buried ("soil on wood") under soil. Hugelkultur, which means "hill culture" in German, can be implemented on a small scale in backyards or on a large scale, as demonstrated by Sepp Holzer, a renowned permaculture practitioner who uses hugelkultur in his terraced gardens. This technique involves layering logs, branches, twigs, and even whole trees, creating a foundation for the bed. This buried wood becomes "a sponge to hold water", reducing or eliminating the need for irrigation. As the wood decomposes, it attracts beneficial microorganisms and creates air pockets, leading to nutrient-rich, fertile soil. Hugelkultur helps gardeners "grow a typical garden without irrigation or fertilization". This technique can be used to grow garden plants like "rhubarb", "potatoes", and more. Hugelkultur is an example of permaculture design, which emphasizes sustainability, self-sufficiency, and working with natural systems
