what is the smallest hydroelectric system?

seth

i was thinking about taking a water pump and trying to light an LED using a small stepper motor or something. what is the smallest application of this. today i bought a small dc motor and got it to light an LED by putting the spindle to a spinning wheel (bike tire) but there is no way i could get enough power from a water pump to turn that little motor fast enouph to light an led. so maybe i need a bigger dc motor and turbine? anyway...basically what is the smallest application possible to light the smallest energy using light. thank you!

Answer
Pico hydro power. It is a term used for hydroelectric power generation of under 5 kW. It is useful in small, remote communities that require only a small amount of electricity - for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes. Even smaller turbines of 200-300W may power a single home in a developing country with a drop of only 1 meter. Pico-hydro setups typically are run-of-stream, meaning that dams are not used, but rather pipes divert some of the flow, drop this down a gradient, and through the turbine before being exhausted back to the stream.
