Transcript of Engineers Without Borders

Electricity Generation Project Engineers Without Borders - Boston University What's the need for Electricity? Naluja health clinic - refrigerator

Cell Phones

Light bulbs Sustainable Designs Hydro Power

Photovoltaic Panels

Wind Power

Mechanical Power

Biomass Hydro Power Not feasible due to seasonal rains Solar Power Lack of local technical knowledge

Spare parts issue Cultural Considerations EWB - Tufts faced problems in Uganda

Community was very receptive to our design Mechanical Power Wind Power Not feasible for us due to lack of wind in the area Various methods to generate electricity - from soccer ball to bike

Various Bike Designs
Charge as you pedal
Stripped down bike
Roll on/Roll off

Wide variety of applications - water pump
Easy to fix/ maintain Challenges in building/implementing Community Contributions 5-10% contribution

Draw up manual and teach them how to build one (local materials only) Load : Still unsure (not 100% solution)

Overcharge Indicator for Battery

Cost of materials/ amount community can afford Cost and Materials Major Cost Materials :
Car Battery

Low Cost Materials:
Belt Pulley
Nuts and Bolts

Estimated Total Cost : <130 USD Usage For the health clinic, then community

Motivation to pedal? Updates for Second Semester Redesign of Bike Frame
Successful 501B

Universal frame design proves challenging

Chain vs belt Goals for summer and fall semester Travel Team to Naluja - better data about Naluja, gauge willingness of the community, materials available

Engineering is the easy part - cost to the community and their needs are the only priority

Over the summer - continue prototyping of bike stand
Start prototyping in the fall
