Build a hydro generator!


People have been using the power of moving water to supply energy for almost as long as we've used wind. Archaeologists have discovered descriptions of water wheels used for grinding grain that date back more than 3,000 years. Today, the energy of falling water is maily used mainly to drive electrical generators. As long as snow and rainfall continue to fill streams and rivers, water can be a renewable source of energy.

Build your own water-powered electrical generator with plastic spoons! With the construction plan, you use plastic spoons and other simple supplies to build a model of a simple micro-hydro system. Your model will generate a surprising amount of electricity, providing you have a supply of pressurized water, such as from a lab sink.
