Vertical turbine hydro generator system. Low rpm permanent magnet generator, home made

As seen on "America Unplugged" season 1 episode 5 now on netflix . I rebuilt my 13 year old hydro system. Charges a battery bank that powers a inverter that runs two refrigerators. I added adjustable turbine height for different water volumes. I used #18 wire and 40 wraps on the windings. I get higher voltage at even lower RPM. I show how I true up the stator and do the windings. Here is a link to the magnets: http://amzn.to/2n5hsCL Drill press: http://amzn.to/2o6t7pX
