FREE HYDRO ENERGY - OWN PELTON

this is a home made hydro powered 12volt battery charger which charge 3 tractor batterys .
the 12 volt batterys feed a invertor which supplys 230v ac to all our house lights and tv.
i am posting this to be a aid to anyone else that may try to generate mini hydro power .
the water head hight is 2.75 meters its 400mil diamater pipe and its 90 meters length.
the toatal output is 9 amps 12v dc 24/7.
the pma generator is a 3kw 36volts 3ph ac output at 3000 rpm.
the reason i get only 9 amps is my rpm are aprox 900 rpm .
