Wild Chick Farm
Wild Chick Farm. In the fall of 2005 Sarah Brunner and Shail Pec-Crouse, started a commercial pastured chicken operation in Arcata, California. The first four months see update of business were spent learning from other successful models, experimenting with different equipment, suffering through trials and tribulations, getting our hands bloody and planning improvements to our system. Throughout it all we have been guided by our core values of humane husbandry and sustainability.

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.

"It can be built as a : Do-It-Yourself (DIY) project where expert masonry skills are not required" and "by using common and inexpensive materials available anywhere."

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

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.
