Participatory Methods for Sustainable Community Development

Saturday, April 9th, 10am to 3pm
Stephens Lounge in the MLK Student Union

Join us for this exciting workshop to learn and practice participatory methods. We all know that we're supposed to include the community in planning and implementing projects, but how do we actually put this into practice? Come learn how to use pictures, open-ended stories and other simple but powerful activities to encourage learning. Develop your skills to open up dialogue around community problems and empower people to solve their own problems. We will come prepared with examples from water and sanitation, but also focus on how to modify the basic techniques for use in different situations. Bring your favorite teaching/learning activity to share!

Saturday, February 26th, 10am to 4pm
3107 Etcheverry Hall, UC Berkeley
Number of participants: 25

This homebrew workshop is a quick-moving, hands-on class, where you will make several small batches of biodiesel, learn safety and basic lab processes, test oil and biodiesel for quality, and work with ethanol and discuss acid-base biodiesel processes.

Students will also make a full size batch of biodiesel in a homebrew reactor, we will demonstrate washing processes, demonstrate purification of glycerol and it's uses, discuss biodiesel reactors and demonstrate methanol recovery equipment, discuss solar heating for the process, discuss heat exchangers, use of vacuum for energy savings, dewatering of waste vegetable oil, safe glycerol/waste oil burners for process heat, biodiesel co-ops and production groups, and more.

Water Filter Design

Sunday, November 21st: 1-4pm
RAEL (4152 Etcheverry Hall), UC Berkeley
          Number of participants: 10

A team of Berkeley students is designing a low-cost water filter for the Bheram Slum community in Bombay, India.  We are looking for your expertise or simply your creativity and motivation to help us generate some design ideas.

At the Workshop We Will:
-Present background on the project and the community
-Give a short tutorial on available low-cost filters and how they work
-Breakout into design teams
-Reconvene to present ideas and develop a bill of materials for the best designs

Solar Desalination

Saturday, October 30th: 11am
RAEL (4152 Etcheverry Hall), UC Berkeley
          Number of participants: 15

Fermin Reygadas (ESW-B Agua SALud project member) will give a brief presentation on the current state of the technology, its potential applications and barriers.

Then students will form groups and participate in designing and building Solar Distillation Units.
The Agua SALud team plans to go back to Baja California Sur next summer to asses the viability of introducing Solar Distillation Units in remote communities.

During the workshop, Mouhsine Serrar (smile@sunsmiles.org) a member of RAEL, will give a brief presentation of some project opportunities in Solar Cookers and Water Desalination for next summer in Morocco.
