How can I build a water turbine for my Science project?
If you notice that on your link there is a disclaimer which states that the watermill shown doesn’t generate electricity. Its just a landscape decoration driven by an electric water pump and it would turn slowly and with not enough enery to light a bulb even if it did. You know electrical generation is a conversion of mechanical movement into electrical power. How that motion is created is independent of the conepts of how electricity is produced. Meaning you can still show that an electric generator works no matter how you spin it. (by hand, wind, water, a bicycle, a motor, or an engine) Generally the only difference between a wind vs water turbine is the dirving fluid, air vs water. If your really dead set on a water powered system then get a hold of a small centrifical pump and pass water through it which will cause the shaft to spin. Look at this months issue of Nuts and Volts magazine http://nu
