I recently came across this Article which talks about how Solar Power is being used for teacher training purpose. If the Program is successful then plan is to scale it further.
The cost of training each teacher would be as low as $150 per year.
Train for Tomorrow, a program run by the non-profit Varkey Foundation with $2 million funding from Dubai Cares, a philanthropic organization, might have a high-tech, low-cost answer: interactive distance learning that can reach schools all over the country thanks to satellite connection, and solar-powered computers which don’t fear power cuts.
