Today only - Special invite for Appropedians to the Buckminster Fuller Institute Celebration in San Francisco on April 16th. If you are in the San Francisco Bay Area, check it out, this celebration will be quite excellent. |
We began with a very small flock of 175 birds and decided to try two different models of raising them on pasture to see which model worked the best for our situation. We compared the two models by looking at efficiency, loss to predators, land impact cost, fossil fuel use and mobility which strongly effects efficiency, land impact and fossil fuel use. After working with both models for a couple of months we came to the conclusion that the Chicken Tractor (CT) model is most appropriate for raising meat chickens and the Hoop House (HH) model is more appropriate for raising laying hens. The CT is better for meat production because it is more cost effective and mobile and there is less predation. The CT is also important for pasturing laying hens for their first few months since there are less predator risks. The Hoop House is better for egg production because it accommodates nest boxes and roosts.

The basis of natural building is the need to lessen the environmental impact of buildings and other supporting systems, without sacrificing comfort, health or aesthetics. To be more sustainable, natural building uses primarily abundantly available, renewable, reused or recycled materials. The use of rapidly renewable materials is increasingly a focus. In addition to relying on natural building materials, the emphasis on the architectural design is heightened. The orientation of a building, the utilization of local climate and site conditions, the emphasis on natural ventilation through design, fundamentally lessen operational costs and positively impact the environmental. Building compactly and minimizing the ecological footprint is common, as are on-site handling of energy acquisition, on-site water capture, alternate sewage treatment and water reuse. |
ENGR 215 Introduction to Design projects – Spring 2010: RCEA: Two labs of the Spring 2010 semester of Engineering 215 worked with the Redwood Coast Energy Authority to build energy education boxes for classrooms in Humboldt County. These boxes are designed for different K-12 grade ranges and cover one of three topics: energy conservation, renewable energy or climate change.
