Transcript of Engineers Without Borders
Light bulbs Sustainable Designs Hydro 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 :
Low Cost Materials:
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
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
