Homemade Low RPM Generator

I made this powerful electric generator from scratch using cheap ferrite magnets, iron cores were cut out of sheet iron, 18 coils 40 turns each hand winded around the cores i made from those iron pieces..

it Generates 12 Volts 8 Amps AC at 120 RPM, this alternator i need to connect it to some thing like a wind turbine or steam engine or a pedal to generate electricity when the power is out.

u can charge 12 Volts Lead acid battery and use a buck converter and a usb port to charge smart phones with it, charge your flashlight or even use a iron core transformer to make 220/110 volts AC and charge your laptop or turn on your computer or a electric fan.
