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

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.

WOFATI, an acronym coined by Paul Wheaton, stands for Woodland Oehler Freaky-cheap Annualized Thermal Inertia. It defines a type of earth-sheltered, passive building that blends affordability with energy efficiency. Inspired by the work of Mike Oehler, a pioneer of earth-sheltered building, WOFATI designs use locally sourced, natural materials, such as wood and earth, to minimize both cost and environmental impact. Central to the WOFATI concept is Annualized Thermal Inertia, which utilizes the surrounding earth as a thermal mass to moderate temperatures year-round. This means that the building stays warm in the winter by storing heat from the summer, and cool in the summer by retaining the coolness of the winter, greatly reducing the need for artificial heating and cooling. WOFATI structures typically have a large gable roof on the downhill side, and at least 35% of the uphill wall is made of glass or other light-transmitting material to maximize passive solar gain. WOFATI buildings are ideally situated on or near a woodland, emphasizing a harmonious integration with nature. Allerton Abbey, the first WOFATI, along with Wofati 0.8, are examples of this building style and can be found at Wheaton Labs.

Some people have experienced greater health, better skin and more luxuriant hair by going "pooless" (no soap or shampoo in the shower). Also known as "pure water showers". Save money on buying stuff, plus shorter showers means saving money on hot water. And best of all, shorter showers means a few extra minutes on busy mornings.

The lorena cooktop, a specialized component of rocket stoves, is designed for optimal heat transfer and cooking efficiency. It features a metal plate with a strategically placed central hole situated directly above the rocket stove's burn chamber. This central hole allows for the placement of large pots, facilitating rapid heating through direct contact with the intense flames generated by the rocket stove. The metal plate surrounding the central hole serves as an additional cooking surface, providing versatility for a wider range of cooking needs. This dual-purpose design is meant to maximize heat utilization from the rocket stove, contributing to both energy efficiency and reduced cooking times. Discussions about the lorena often involve integrating it into an outdoor kitchen setup, further enhancing its practicality. The lorena embodies the continuous innovation within rocket stove technology, aimed at improving heat transfer and enhancing cooking performance.
