Here is a pull-out from the article:
Since 2004, the Barefoot College, in Tilonia, India, has trained about 250 illiterate and semiliterate women from rural, unelectrified villages in 41 countries to be solar engineers. After six months of training, these women have provided more than 15,500 houses with solar electricity in their home countries. The government of India covers all expenses—245,000 rupees (about $4,400) per woman, plus airfare. The college has trained an additional 700 men and women from rural India, including Moceiwasa's teachers.Is that freaking amazing, or what?! Imagine spending just 4400-dollars on each person in the US who wanted to learn how to build solar grids for their communities.
