35 results about "Appropriate technology" patented technology

Appropriate technology is a movement (and its manifestations) encompassing technological choice and application that is small-scale, decentralized, labor-intensive, energy-efficient, environmentally sound, and locally autonomous. It was originally articulated as intermediate technology by the economist Dr. Ernst Friedrich "Fritz" Schumacher in his work Small is Beautiful. Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered.
