This is a cross-flow turbine, basically a water wheel turned by stream to produce energy. This provides energy without the cost of fossil fuels; while the only time and energy used to work on it is occasional maintenance and set up. This would used in developing areas around the world because it is much cheaper and less time consuming to make. The material cost of this turbine itself is significantly reduced using 3D-printing.
Bill of Materials[edit | edit source]
- PLA or ABS Filament (1.75mm)
- All of the STL files and the SCAD files are here.
- Hexagon axle shaft
Tools needed[edit | edit source]
- MOST Delta RepRap or similar RepRap 3-D printer
- Exacto Knife
Skills and knowledge needed[edit | edit source]
Technical Specifications and Assembly Instructions[edit | edit source]
- Place 3/8" hexagon shaft through printed turbine.
- Connect shaft to electric generator.
Common Problems and Solutions[edit | edit source]
- Poorly fitting axle shaft, or broken vanes are both fixable with a small amount of epoxy
Cost savings[edit | edit source]
- The micro-turbine is about $1.00
- Cost savings depend on the size of the wheel.
- Micro-turbine plants can cost up to $20000.
