Juabar provides solar powered charging kiosks in off-grid areas of Tanzania.
They lease the kiosk to entrepreneurs who then make money by providing electricity to their communities.
Aside from the fact that they designed the service using participatory design methods, the service is great because it allows for both infrastructure and economic development in the region.
A service offering a much-needed infrastructure, and much-needed economic opportunities, designed with the community it is for. Lovely.
