Tutorial: how to build a 100W hydro-power-plant from scrap-material only 

This is the result of bachelor-theses in mechanical engineering at the ZHAW school of engineering (Winterthur, Switzerland)
Autors: Robin Vetterli and Fabian Mohnen
The tutorial explanes how you can build a 100W hydro power plant based on the archimedes screw principle.
Building time: 80 to 100h
Skills: Metal cutting, welding
Material:
- 200L oil barrel (see details in film)
- bycicle (steal frame)
- spiral tube (d = 30cm)
- car alternator (see details in film)
- 2 wheels with funcional bearings
- 2.5 m2 of sheet metal or corrugated iron
- 10m steel tube for frame
How to start:
- watch video
- find a small river with 50 L/sec flow, a 0.5 m high step and that you are allowed to use for your powerplant
- find accoring materials in you nearby scrap-yard
- find somebody who has a welder
- start building
- place the plant 30° to the horizontal into the river (be careful the screw will start immediatly and can harm you
- connect the wires according to the video
- use the electicity
- maintain the power-plant if needed
