 Hugh Piggott’s manual has been translated into more than ten languages and it has been estimated that more than 1,000 locally manufactured small wind turbines have been constructed based on Piggott’s design, and currently many of them are in operation around the world.The open nature of these designs has given rise to a global community of designers, builders and users that continue to apply and further develop the technology in a bottom-up innovation process, resembling an open-source hardware community.Since 2012, the Wind Empowerment association has managed to network most of the organizations involved with locally manufactured small wind turbines in the world, aiming at empowering the activities of these organizations and at performing joint research and projects while openly sharing knowledge.
