Question:
How do I generate electricity using no moving parts. (like using dripping water)



Replies:
There are many ways to generate electricity with no moving parts. Batteries do it constantly. Another of the many ways is a device called a thermocouple. This device generated electricity by differences in temperature. There are many other ways. I just thought of another way -- I suppose that there are actually dozens, so as you also think of some, write to my login name and we can discuss how each works -- how about solar energy as in solar cells?

A way to use your dripping water to generate electricity is to use the piezoelectric effect. The piezoelectric effect uses pressure on amaterial to create a current of electricity in that material. Quartz or Rochelle salt generates a current across it when a mechanical pressure (such as dripping water) is applied. Granted dripping water will not cause a large current, but a current none the less. The piezoelectric effect is mainly put to use in your mom or dad's record player. By rubbing the needle (a small piece of quartz probably) over the rough edges of the phonograph record, a small current is produced. That small current goes to an amplifier which increases the current level. That current is then sent to the speakers and then sound is created by the speakers. I too am glad to see your interest in science at an early age. Stick with it. Science is fun even when you get older.
