Near the base camp in the district of Tsugaru passes along with the tourists, I have built mini-hydroelectric power plant with a capacity of 15 W and voltage 220 V. This is sufficient for night camp lighting energy-saving lamps or LEDs. Day also can charge batteries of cameras and camcorders that can connect a radio or tape recorder.
Mini-hydro — damless type. Scale rotor blades — 1700 mm, width 800 mm, height -250 mm blades rotational speed of 14-16 rpm. The multiplier transmitting rotation from the rotor to the generator (tractor DT-54) — three-stage V-belt transmission with a total gear ratio i = 130. 220×8 transformer In a power of 250 watts.
