Technology for the Poor, a non-profit charitable organization based in Westerville, Ohio, discuss their design for low cost wind energy in this excerpt from their manual:
"In recent decades due to the search for renewable energy, many efficient wind generators have been developed and tested. Today, we see enormous wind generators dotting the landscapes of many states. Wind generators, especially the recent ones, are quite sophisticated, costly and needs expertise to maintain and operate. The most appropriate wind machine for use in less income countries was found to be a simple machine invented by a Finnish Engineer, Savonius."
