This is a stylized reproduction of a functioning hydroelectric plant. It can get about 3/4 volt with 0.9 A .
I created it for a contest in my school and I used only:
- A plexiglass cylinder;
- Some pipe;
- A resistant glue;
- Some BallBearings and rods;
- A dynamo (without internal resistance to get more energy);
- A wood base;
- Water (obviously).
At the end I can light some Leds (6 or 7).
