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 ...
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.
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.
"HUSP," an acronym for "Horticulture of the United States of Pocahontas," is a term coined by Paul Wheaton to represent a hypothetical agricultural system practiced in a fictional nation called the United States of Pocahontas (USP). In this imagined scenario, Pocahontas emerges as a strategic leader, thwarting European colonization and leading to the formation of the USP. This fictional nation's agricultural practices are characterized by a deep respect for the Earth, rejecting environmentally harmful methods like plowing and the use of petroleum-based fertilizers and pesticides. Instead, they embrace sustainable techniques akin to permaculture and traditional Indigenous knowledge, leading to superior food production, enhanced public health, and a thriving "health tourism" industry. Wheaton utilizes HUSP as a thought experiment, inspiring innovation and pushing the boundaries of contemporary permaculture. He proposes a real-world project involving a 2,000-acre plot divided into smaller sections where practitioners of permaculture, biodynamic farming, and native plant cultivation can experiment and share knowledge, collectively striving to "rediscover" the principles of HUSP and advance sustainable agriculture. This project emphasizes the importance of collaboration and government non-interference to foster creative solutions for a future where food production harmonizes with nature.
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.
