This is by far the most technically advanced innovation I’ve found for a five gallon bucket so far. Sam Redfield developed this design to provide a source of electricity that can be built cheap and hooked up to any source of flowing water – including irrigation systems, creeks and streams, or even sewage systems.

If you are very mechanically capable, you can download the full 35 page design manual and attempt to build your own five gallon hydroelectric power plant.

The following video shows some of the assembly, as well as the generator in action.
