The lorena cooktop is a highly effective design for rocket stoves, as it maximizes heat transfer and cooking efficiency. This specialized cooktop, featuring a metal plate with a central hole positioned above the burn chamber, enables rapid heating of large pots through direct exposure to the intense flames. The lorena's design prioritizes efficient heat utilization from the rocket stove, resulting in faster cooking times and reduced fuel consumption. Additionally, the metal plate surrounding the central hole serves as a secondary cooking surface, offering versatility for various culinary tasks. Once a large pot reaches the desired temperature, it can be moved to the surrounding cooktop, and the central hole can be covered with a piece of metal to maintain heat. This dual functionality makes the lorena a practical and energy-efficient cooking solution, suitable for both large-scale and smaller cooking needs. The integration of a lorena into an outdoor kitchen setting is often proposed, further enhancing its practicality and convenience.

he willow feeder system is a sustainable and "freaky-cheap" approach to human waste management developed by permaculture expert Paul Wheaton. This system utilizes a dry environment inside sealed garbage cans to mummify human waste, which prevents composting and the release of pathogens. The system is designed to be a safe and effective alternative to conventional septic systems and sewage treatment plants. A small amount of sawdust is added to each can, mainly for aesthetics. After two years, the resulting pathogen-free material, referred to as "willow candy," can be safely used as fertilizer for trees that can handle its high nutrient content, known as "poop beasts." These trees include willow, cottonwood, poplar, and bamboo. The willow feeder system embodies permaculture principles by transforming human waste into a valuable resource for growing beneficial plants while minimizing environmental impact.

Hugelkultur, is a permaculture garden bed technique where wood is buried under the soil. It can be built in a variety of shapes and sizes, and can be used for growing a variety of "garden plants". The decomposing wood acts "like a sponge to hold water", making hugelkultur ideal for areas that receive little rainfall. Over time, the wood shrinks and creates air pockets, resulting in a self-tilling garden bed. This "soil on wood" technique helps to retain moisture and nutrients in the soil, which benefits the plants. Hugelkultur is an environmentally sustainable gardening technique because it uses wood that might otherwise be discarded.
