The use of motors as generators is now well proven and promises to be an important element in establishing self sustaining local capacity for village scale hydro in developing countries micro hydro is a valuable source of energy for rural industries and village electrification schemes. This micro hydro installation uses pumps as turbines and 3 phase motors as single phase generators yes you can there is 210 feet of head 92 psi and 550 ft of 8 inch welded steel penstock. The generator type associated with microhydro power is normally either a permanent magnet a wound field or induction most smaller turbines use permanent magnet generators some of which have adjustable gaps between the magnets and the windings for tuning the output. This video covers the installation of a microhydro system in a mountain stream the goal is to be able to charge a 24v battery bank and produce about 10000 watts of power a day. Small scale hydro micro hydro is the cheapest way to power an re home the price per watt hour is far cheaper than photovoltaics pv and even less than wind streams run twenty four hours a day seven days a week and often 52 weeks per year the resource is much more site specific than solar
