Pico hydro is hydro power with a maximum electrical output of five kilowatts. Hydro power systems of this size benefit in terms of cost and simplicity from different approaches in the design, planning and installation than those which are applied to larger hydro power. Recent innovations in pico hydro technology have made it an economic source of power even in some of the worlds poorest and most inaccessible places. It is also a versatile power source. AC electricity can be produced enabling standard electrical appliances to be used and the electricity can be distributed to a whole village. Common examples of devices which can be powered by pico hydro are light bulbs, radio’s, televisions, refrigerators and food processors. Mechanical power can be utilized with some designs This is useful for direct drive of machinery such as workshop tools, grains mills and other agro-processing equipment.
