Alternative Power Source Investigation for Kinkajou Projectors
[attachment=36583]
Background
Illiteracy Problem
One in five adults worldwide cannot read.
In rural regions of West Africa, up to 75% illiterate.
Causes for Illiteracy (according to Barbara Garner of the World Education Organization)
The lack of resources: access to books and lighting
Design that matters (DtM), a Massachusetts nonprofit, has tackled this particular problem by designing the Kinkajou Portable Library and Projection System.
Current Power System is Expensive
DtM’s working power system
a motorcycle battery and solar cells combination
Not viable based on cost constraints (target $25)
Power system costs $130
Solar panel $80
Battery + rest of package $50
