African "Kulibin" and homemade power

As they say, necessity is the mother of invention. In one of the poorest African countries - Malawi, the guy at the age of 15, he built a wind farm of debris. The energies of this station enough to power the whole house.
Only one thing I do not understand - from a guy in one of the poorest countries in Africa such knowledge?
