If you can make something rotate, you can convert that to power using a DC motor. But using water power has some caveats. What will happen if your machinery freezes during the winter? How damaged will your equipment be? Will you have to dismantle the generator during freezing temperatures?
Here are some interesting ways to generate power with flowing water.
- Very simple generator made with DC motor and an LED. Good to understand the concept.
- USB charger and battery bank, charged by faucet water. Uses a very tiny DC motor.
- Hydropower generators in 5 gallon buckets. Easily portable.
