How To Build A Five Gallon Bucket Hydroelectric Generator

How To Build A Five Gallon Bucket Hydroelectric Generator

hydroelectric bucket

The power of the generator is dependent on the load that is connected to the system. The maximum power of 90W was achieved when a resistive load of 5 ohms was connected to the generator. As an example, a power of this magnitude is sufficient to power three 30W UV water treatment systems. Alternatively, it could power up to 80 one watt LED lights (dependent on line losses and draw from the inverter used).

Here is a list of materials that you will need ( i know the list is large but i bet you have most of them in your workshop already πŸ™‚
