About this model
This hydroelectric power generator has many possibilities for a school science fair project. Here are a few independent variables that can be adjusted in an experiment * Gear ratio -- I have included four different gears for the generator and turbine to try * Load resistance -- Drive a set of resistors ranging from 1 Ohm to 1 kOhm * Water flow rate * Water height * Turbine design -- Design your own turbine! We used this design for my daughter's 7th grade science fair project. This design remixes the turbine designed by Victor Barahona at and the parametric gears by Droftarts at We drove a 3W RGB LED in series with a 3.3 Ohm resistor (wear your sunglasses, these LEDs are bright!)
