Waves and power generation
Our hypothesis that wave cycles at a higher frequency and at a higher amplitude will produce higher electrical voltages, is proven to be true.
Wave energy is produced by placing electric power generators on ocean surfaces. There are several methods such as the Pelamis wave energy converter, Anaconda wave energy converter and the Wave Dragon energy converter. The world’s first wave farm was built off the shores of Portugal using three 750kVA Pelamis wave converters.
This science fair project may be repeated, to evaluate the impact of using water of a different density (eg. sea water). You could also try to make waves by blowing wind across the surface of the water using a large fan, and then changing the direction of the fan.
