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 berm shed is more than just a simple storage structure; its construction incorporates advanced techniques that prioritize sustainability, durability, and integration with the natural environment. Earthworks play a crucial role, as careful shaping of the landscape is required to create the berm that covers a portion of the shed's sloping roof. This berm acts as a natural insulator and thermal mass, helping to regulate temperature inside the structure. The "attic" cell design, as discussed in source, involves a specific configuration at the termination ends of the berm shed, further enhancing its thermal efficiency. Round wood timber framing, a technique using logs instead of dimensional lumber, is often employed, lending structural strength and a rustic aesthetic. A key consideration is the long-term durability of the wood in contact with soil. Source emphasizes the importance of peeling the bark from posts before burial to reduce the probability of rot, highlighting the evolution of construction techniques for increased longevity. Additionally, using gravel in post holes, as described in source, helps with drainage and further protects the wood from moisture. These advanced concepts, when combined, result in a berm shed that is not only functional and visually appealing but also a testament to sustainable building practices deeply rooted in permaculture principles.
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.
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.
Dry outhouses offer a multitude of positive environmental impacts, aligning perfectly with the core principles of permaculture and sustainable living. Unlike conventional flush toilets that waste gallons of clean water and contribute to pollution, dry outhouses conserve water and prevent contamination. The "no pee" policy, combined with effective urine diversion systems, further minimizes the volume of waste and potential for groundwater pollution. The use of sawdust not only controls odors but also facilitates a dry composting process, essentially mummifying the waste over time and reducing it to poop-jerky after two years. This aged material is then safely used as a nutrient-rich fertilizer for "poop beast" trees like willows, poplars, and cottonwoods. This willow feeder system not only prevents harmful waste from entering the environment but also actively enriches the soil, promoting the growth of beneficial plants and trees. By avoiding chemical fertilizers and promoting natural decomposition, dry outhouses contribute to a healthier ecosystem, aligning with the HUSP (Horticulture of the United States of Pocahontas) concept that emphasizes sustainable land management practices. Furthermore, the absence of a water-intensive septic system eliminates the risk of leaks and contamination, safeguarding groundwater and promoting ecological balance. Therefore, dry outhouses offer a compelling example of how simple, well-designed systems can have a profound positive impact on the environment.
