PROPOSED EWB BOSTON PROFESSIONALS PROGRAM IN TANZANIA SIEMENS VAI, WORCESTER MAY 2011

IDEA FOR EWB PROGRAM Central hub for a group of families Biogas plant and distribution - $1000 Cooking Refrigerator? Solar panels and distribution – $5 per watt Light Battery charging Water pump? Water well?

BENEFITS Clean indoor air Health No deforestation Improved light Reading etc. in evening Savings Time for gathering wood (dung is closer) Time of recharging cell phones Cost of kerosene

CHALLENGES Efficient cheap design Proof that it’s of benefit to the families Funding (until self-sustaining) Maintenance after EWB leaves Business development Local and national politics Fitting in with tribal culture

IN 5 YEARS (OR MAYBE 10) 500 installed systems, with every one being used Ten teams of EWB Boston engineers, each working in one village, responding to the unique requirements of that village Local businesses supplying parts for new hubs and for maintenance Good relationships with local and national governments and other NGO’s Smooth supply of funding
