Windmillprint-crop.jpg As part of a 3-D printing class, graduate students will be designing printable open-source appropriate technology for sustainable development. If you want a technology designed to be 3-D printed, post your ideas here. Chosen designs will be made and open-sourced for the global community. Deadline Nov. 13, 2014


Sarah the hardest worker who is always chuggin' away.
CCAT yurt rainwater catchment. The long history of rainwater collection, can be traced (in recorded history) as far back as ancient times some 3,000 years ago (850 BC) if not even farther. The need for water is a basic human essential for maintaining life, without it, no civilization could have prospered. Rainwater collection in ancient Constantinople is one of the last megalithic structures of its kind.

The CCAT Rainwater Catchment Group consists of: Sean Colley, Matt de Young, Jessica Radtkey, Sarah Shimizu, and Tiesha Whittaker. Our project for ENGR 114 was to build a rainwater catchment system around the yurt at CCAT on campus at Humboldt State University. The purpose of the rainwater catchment system is to capture and store rainwater in a large storage drum for use to water plants on the CCAT grounds. Water is a resource that is always present around us but not always in an immediately useful form. Therefore, it is necessary that we use innovative and appropriate techniques to capture and transform the water that we have into a useful form of water for our needs.

Greywater, sometimes also spelled as graywater, grey water or gray water, is all of the effluent water from a household, such as water discharged from lavatories (bathroom sinks), bathtubs, showers, clothes washers, and laundry trays. Greywater is not wastewater from a sink used for food preparation, or water closet (toilet) wastewater.

The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it. However, it is not a great risk compared to blackwater (sewage).

Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants.

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.
