Why have these efforts not borne fruit in Indian Sub-continent? Technical Feasibility….1 Mind set : Village sites are remote & bound to be un-competitive –low productivity & quality –Maximum people socially illiterate, suspicious of modern technology No systematic efforts by technical institutions to innovate technologies, management practices for decentralized production---limited expertise Technical education oriented towards organized sector alone

Conceptual Design & Layout towards Farm Profitability & Energy Management Integrating RCTs and Hydro Power Water shed Micro Hydro Water Wheel

HISTORY The first reference to its use dates back to about 4000 B.C., where, in a poem by an early Greek writer, Antipater, it tells about the freedom from the toil of young women who operated small hand mills to grind corn. As early as the first century, waterwheels of the vertical design were replacing the horizontal waterwheel. An early horizontal-wheeled watermill used for grinding grain in Greece was the called Norse Mill. In Syria, the watermills were called "noriahs". They were used for running mills to process cotton into cloth. Of the three distinct types of water mills, –The simplest and probably the earliest was a vertical wheel with paddles on which the force of the stream acted. –Next was the horizontal wheel used for driving a millstone through a vertical shaft attached directly to the wheel. –Third was the geared mill driven by a vertical waterwheel with a horizontal shaft
