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 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

A berm shed is an innovative, earth-sheltered structure designed for storage, blending seamlessly into the landscape while offering practical benefits. This natural building technique utilizes readily available materials like logs and earth, minimizing environmental impact and cost. The berm shed's design, as described in the sources, features a sloping roof covered with soil, creating a natural berm that provides insulation and helps regulate temperature. The round wood timber framing techniques used in its construction, relying on logs rather than dimensional lumber, further enhance its sustainability and aesthetic appeal. The berm shed is often incorporated into permaculture designs, serving as a visual and sound barrier, enhancing privacy, and creating a microclimate for plant growth. Its construction involves earthworks, carefully shaping the surrounding landscape to create the berm and ensure proper drainage. The berm shed's unique design, combining natural materials and earth-sheltering principles, offers a durable, cost-effective, and aesthetically pleasing storage solution that integrates harmoniously with the surrounding environment.

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 "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.
