There are a few charities that help African communities become self-sufficient by teaching farmers sustainable farming techniques, but, as far as I’m aware, there isn’t one that teaches how to power a generator with wind.

This truly inspirational tale also follows the aftermath: how Kamkwamba copes with the subsequent speaking tours, media attention, and being the leader of his south-east African village.
